iPS-Derived EV

Don't decide on the words "iPS-derived" alone.
Review EV as something separate, calmly.

iPS cells grew out of research on returning mature cells to a pluripotent state. The iPS-derived EV discussed on this page is not an explanation of placing iPS cells themselves into the body. An EV is a small particle a cell releases. When the route is made from patient-derived personal iPS, the source, the explanation of it as single-source, the quality records, and the creation period are positioned as an area where research and commercialization are advancing, and a physician then organizes them one at a time during the consultation. We start not from the impression of a name, but from what can be confirmed.

Entry: consultation (physician review) / an explanation of the general flow and its "positioning" (kept separate from the filed plans) / confirming source, quality records, and alternatives / shared before your visit via LINE or email.

Before You Send / Where the consultation begins

What you send, what we confirm,
and which options you discuss with a physician.

iPS-derived EV is not a matter of placing iPS cells themselves into the body; it is a consultation that confirms the source and quality records of an extracellular vesicle (EV). It is not something you receive right away — creation, storage, and quality confirmation are checked in order. Even if not every record is in hand, you can begin a records consultation by sending what you have via LINE or WhatsApp.

What you can send first
  • Existing test, imaging, or health-check data
  • Your wishes (what you want to confirm), medical history, and medications
  • If iPS cells derived from your own cells have already been created and stored, those records
  • Records of consultations or treatments you have received so far

You do not need every record in hand. You can begin a records consultation by sending what you have via LINE or WhatsApp.

Options we organize
An EV is not the cell itself

iPS-derived EV is confirmed for source and quality as an extracellular vesicle. It is not an explanation of placing iPS cells themselves into the body.

Confirming source and single-source

We confirm whether it can be traced as patient-derived and single-source. Anything of unknown origin or whose records cannot be confirmed is not taken as a premise.

Kept separate from the Type-2 MSC / Type-3 NK filed plans

It is not treated in the same framework as the filed provision plans. As a medical area where research and commercialization are advancing, a physician explains it individually.

Physician explanation and consent

We separate what is understood from what is not yet understood. No outcome is taken as a premise.

Based on the records, a physician organizes which options should be considered. The schedule (an estimate for creation and manufacture) is confirmed at the consultation.

Knew / Didn't Know

Have you assumed that "iPS-derived EV"
and "iPS cells themselves" are the same thing?

Reading the phrase "iPS-derived EV" alone, people often take it to mean placing iPS cells themselves into the body. In reality it is a different matter. The EV (extracellular vesicle) discussed here is a small, sac-like particle released by a cell — it is not the cell itself. Rather than the impression a name gives, what to look at is which cell it derives from and which quality records can confirm it. Seeing that before you decide is the starting point.

Even when there are prominent names or papers in the research background, that alone does not determine the quality of an individual product or a medical outcome. The clinic positions this as an area where research and commercialization are advancing, and a physician explains source, quality records, alternatives, risks, costs, and follow-up individually during the consultation.

Source

Can the source be traced?

Which cell it derives from and whose cells it was made from — can this be traced? Particular caution is needed where the origin is unknown, multiple donors are involved, or quality records cannot be confirmed.

Documents

Can the quality records be seen?

Can lot, sterility, endotoxin, mycoplasma, particle count, size distribution, purification process and similar items be confirmed through records rather than a verbal account?

Doctor

Does a physician explain it?

Does a physician set out, within informed consent, that this differs from widely established standard care in Japan, and separate what is understood from what is not yet understood?

What To Confirm

Before the product name,
there are records to confirm.

The phrase "iPS-derived EV" alone is not enough for a medical decision. What you want to see is source, manufacturer, lot, certificate of quality, storage and transport, the points that should be explained separately from care that is widely standardized in Japan, and the physician explanation and follow-up at our clinic.

01

Not iPS cells themselves

iPS-derived EV is not an explanation of placing iPS cells themselves into the body. We confirm the source and product specifications as an extracellular vesicle.

02

Confirming standardization

We confirm the supporting records for product quality: lot, certificate of quality, particle count, protein amount, sterility, endotoxin, mycoplasma, and storage and transport conditions.

03

Boundary of responsibility

Within informed consent we make clear the boundary that product quality rests with the manufacturer, while medical judgment, explanation, and follow-up rest with our clinic.

EV Basics

An EV is a small particle of information.

EV stands for extracellular vesicle — a small, sac-like particle released by a cell. It is not the cell itself. As a particle that has left the cell, we trace its source and contents through records.

Source

Confirm it as patient-derived and single-source.

Personal iPS-derived EV is explained as a route made from the patient's own cells. Unlike products derived from multiple donors, it matters that whose cells it was made from can be traced.

Particle

Look at particle count and size.

Particle count gives a rough indication of amount, and size distribution shows the spread of particle sizes. Number or size alone, however, is not a basis for judging a medical outcome.

Filter

Recovery, purification, filtering steps.

There are steps to recover EVs from the culture medium and reduce unwanted components and differently sized material. We look at which method is used to purify and which records confirm it.

EV Cargo Literacy

Cargo means the "contents" an EV carries.

Cargo means freight. If you picture an EV as a small envelope, the cargo is the information inside it — proteins, RNA, lipids, and so on. What matters is not the size of a number alone. We look separately at what may be contained, by which method it was measured, and whether it can be confirmed in records lot by lot.

Envelope

The EV is the envelope

A small, sac-like particle released by a cell. Not the cell itself; we look at the source and quality of it as a particle.

Cargo

The contents are not one thing

Research databases report many EV-related proteins, mRNA, miRNA, lipids, and more. They are sometimes described in the thousands, but that does not mean all of them are inside a single particle.

Quality

Confirm it in records

Rather than an impression that "a lot is in there," we confirm particle count, size distribution, protein amount, purification process, sterility, endotoxin, mycoplasma and similar items as records.

Reference: public databases such as ExoCarta and Vesiclepedia organize molecular information related to EVs. These help in understanding the research background; they do not indicate the quality or treatment outcome of an individual product.

Quality Documents

Look beyond the research background
to the quality records at release.

iPS-derived EV is not something to decide on by a research name or manufacturer name alone. Even where a manufacturer or research institution has records or papers, we do not treat those as the deciding factor; we organize them as confirmation records that trace source, manufacturing, lot, release decision, and storage and transport.

Rather than relying on a verbal account, we read the determination results — sterility, endotoxin, mycoplasma, particle count, size distribution, and the recovery, purification, and filtering steps — in the per-lot quality records. This is so we can explain separately what can be confirmed and what is still not yet known over the long term.

Lot

Manufacturer & lot number

We confirm where it was made and under which lot it was shipped.

Release

Release date & expiry

We look at when it was determined and under which conditions the record applies.

Test

Sterility & endotoxin

We confirm, in the records, the determination items related to contamination risk.

Storage

Mycoplasma & storage/transport

We look at items to confirm for culture-derived products together with temperature and transport records.

Particle

Particle count & size distribution

We confirm how many particles are contained and how the size range is presented.

Process

Recovery, purification, filtering

We confirm in the records how unwanted components and differently sized material are reduced.

Source

Patient-derived & single-source

We confirm whether it is a route traceable as patient-derived rather than derived from multiple donors.

Unknown

Known vs. not yet known

We explain separately the items that can be confirmed in records and the points still not yet known over the long term.

Consent Boundary

What a physician explains is
what should be confirmed before you decide.

iPS-derived EV is not treated as the same as the Type-2 MSC or Type-3 NK filed provision plans. Positioning it as a medical area where research and commercialization are advancing, a physician organizes and explains individually during the consultation that it differs from widely established standard care in Japan, along with quality records, alternatives, risks, costs, and follow-up.

An area that needs physician explanation

Without assuming it is the same framework as widely established standard care in Japan or a filed regenerative-medicine provision plan, we organize its boundary, what is understood, and what is still not yet understood.

Product quality

We confirm the quality records provided by the manufacturer and explain them to the patient.

Medical judgment

At our clinic we are responsible for physician explanation, feasibility, follow-up, and the contact arrangements in case of an adverse event.

Informed consent

Without presupposing a result, we explain separately what can and cannot be confirmed.

iPS Background

The idea of "returning" a cell,
which grew from Professor Yamanaka's research.

This is not something to receive right away; it is a process of creating, storing, and consulting while confirming the quality records.
See the research background and papers →

The 2012 Nobel Prize in Physiology or Medicine was awarded to Dr. John Gurdon and Professor Shinya Yamanaka for the discovery that mature cells can be returned to a pluripotent state.

iPS cells emerged from research that introduces a small number of genes into cells that already have a role in the body and returns them to a pluripotent state. This idea of "returning" is called reprogramming.

However, this page does not explain "putting in iPS cells" or "the body's state being restored." It is a page for organizing the map of how to receive an explanation of iPS-derived EV as an extracellular vesicle and which quality records to confirm.

What to look at first

  • This is not a same-day matter.
  • Creation, storage, and quality records are confirmed in order.
  • Whether a consultation is actually possible is explained by a physician after reviewing the records.
Conceptual diagram explaining the difference between iPS cell research and iPS-derived EV
Step 01

iPS is research background

An idea born from research that returns mature cells to a pluripotent state.

Step 02

EV is not the cell itself

iPS-derived EV is not an explanation of placing iPS cells into the body; it is about how to confirm the small particles a cell releases.

Step 03

Confirm in records

Source, particle count, size distribution, purification, lot, and release decision are confirmed in records, separately from the name.

This is to help understanding before the consultation. Feasibility and individual judgment are confirmed by a physician with records and an examination.

Commissioned creation flow for personal iPS and personal iPS-derived EV
Step 01

Organize before consulting

Organize existing records, wishes, and medical history, and gather the points you want to confirm about personal iPS-derived EV.

Step 02

Create and store iPS

A route to create and store iPS cells from the patient's own cells; the guide time is roughly six months.

Step 03

Confirm EV manufacturing

Manufacturing iPS-derived EV is expected to take roughly two more months, with quality records, storage, and shipment conditions confirmed.

Step 04

A physician explains

Feasibility, cost, risks, and unconfirmed points are explained individually with records and an examination.

This flow is for understanding before the consultation. Actual feasibility and the content of the explanation are confirmed individually.

Personal iPS

Personal iPS is not
something to receive on the same day.

Personal iPS is a commissioned route in which your own cells are collected from urine, skin tissue, or similar and created and stored as iPS cells. Unlike products derived from multiple donors, it can be traced as patient-derived and single-source — this becomes an important point to confirm. Creation involves steps such as infection screening, sampling, reprogramming, quality confirmation, and a certificate of storage.

As a guide, creating personal iPS takes roughly six months, and manufacturing personal iPS-derived EV from there takes roughly two more months. When iPS cells are to be created from now, expect about eight months overall, and the schedule is confirmed at the consultation.

If your own iPS cells have already been created and stored, there may be the possibility of consulting from the EV manufacturing stage. The actual feasibility, timing, cost, required documents, and quality records are confirmed individually after you make an inquiry.

01

Sampling & infection screening

It proceeds from urine or skin tissue and similar. There are items that must be confirmed before creation, such as HIV, hepatitis B, hepatitis C, and syphilis.

02

Creation via mRNA and similar

In creating iPS cells there is a step that changes the cell state using reprogramming factors. We also confirm in the records that it is not something that propagates as an RNA virus.

03

EV manufacturing is a separate step

After the iPS cells are created and stored, we confirm concentration, particle count, size distribution, and the recovery and purification steps, then proceed to manufacturing iPS-derived EV.

04

Confirmed by inquiry

Detailed manufacturer information, creation timing, minimum manufacturing volume, storage, shipment records, cost, and the consent form are confirmed in records after an inquiry.

01

What an iPS cell is

A cell born from research that returns mature body cells to a pluripotent state. It forms a large background for regenerative medicine and drug discovery research.

02

Yamanaka factors

Oct3/4, Sox2, Klf4, c-Myc and others are known as the factors used in research that rewinds the cell state.

03

EV is not the cell itself

An EV is a small particle released by a cell. iPS-derived EV is not an explanation of placing iPS cells themselves into the body; as an extracellular vesicle, we confirm its source and quality records.

04

What to confirm in consultation

A physician explains its positioning as an area where research and commercialization are advancing, along with the manufacturer, certificate of quality, storage and transport, cost, risks, alternatives, and the consent form.

Before You Decide

What to know before consulting.

Does iPS-derived EV mean placing iPS cells themselves into the body?

No. The iPS-derived EV discussed on this page is not an explanation of placing iPS cells themselves into the body. An EV (extracellular vesicle) is a small, sac-like particle released by a cell, separate from the cell itself. We confirm its source and contents through the product specifications and quality records.

Can iPS-derived EV be received on the same day as the consultation?

No. In the route made from patient-derived personal iPS, there are steps such as infection screening, sampling, reprogramming, quality confirmation, and a certificate of storage; when iPS cells are to be created from now, expect a corresponding period overall. The actual feasibility, timing, cost, required documents, and quality records are confirmed individually after you make an inquiry.

Is iPS-derived EV the same framework as Type-2 MSC or Type-3 NK?

It is not treated as the same. Positioning it as a medical area where research and commercialization are advancing, a physician organizes and explains individually during the consultation that it differs from widely established standard care in Japan, along with quality records, alternatives, risks, costs, and follow-up.

If the research background has prominent names or papers, does that mean quality has been confirmed?

No. Even with a research name, manufacturer name, or papers, that alone does not determine the quality of an individual product or a medical outcome. We confirm source, manufacturing, lot, sterility, endotoxin, mycoplasma, particle count, size distribution, purification process and similar items in the per-lot quality records.

What is reviewed to confirm an EV's source?

Rather than the name, the quality records: source, donor, origin, contamination measures, shipment records and similar. Particular caution is needed where the origin is unknown, multiple donors are involved, or quality records cannot be confirmed; our clinic has a physician explain those whose source and quality records can be confirmed. For personal iPS-derived EV, we confirm whether it can be traced as patient-derived and single-source.

Consultation

Begin with records and physician explanation.

We confirm product quality, the positioning as an area where research and commercialization are advancing, the boundary of responsibility, and informed consent, and a physician explains individually.
