Where Do Your Cells Go? A Patient-Friendly Explanation of Collection, Processing, and Administration

For autologous stem cell therapy, your cells go through three stages after collection — culture and purification at a cell-processing facility under clean-room conditions, quality testing, and finally administration by IV infusion — and you can ask any clinic to explain each stage plainly, without relying on unverifiable certification claims.

Collection

A small volume of your own adipose (fat) tissue is collected from the abdomen under local anesthetic, in a brief outpatient procedure designed to minimize physical burden. Before this happens, you undergo an infectious-disease blood screening, and your physician reviews your history for conditions that would make collection inappropriate.

Culture and purification

Your cells are then cultured and purified at a cell-processing facility under clean-room conditions, typically over several weeks. This is why autologous stem cell therapy is usually planned across two visits to Tokyo rather than a single trip — most patients return home during this window, since nothing further is required from you personally until the second visit. Our International Patient Guide covers this timeline in more detail.

Quality checks before release

Only cells confirmed sterile and genetically stable are released for use. This checking step exists specifically so that cells that don't meet those criteria are not used, rather than being a formality applied after the fact.

Administration and follow-up

Purified cells are reintroduced to your body by intravenous infusion, followed by scheduled reviews to monitor your condition and response. Follow-up continues remotely with your physician after you return home, for as long as your treatment plan requires — this doesn't replace local emergency care, so urgent symptoms should go to a local provider first, with your StemCellor physician informed afterward.

What "clean-room" and "certified" claims should and shouldn't mean

We describe our processing conditions as controlled, clean-room conditions, deliberately in these general terms. We don't claim a specific third-party facility certification, a named partner facility, or an affiliation with another institution unless that relationship has been independently confirmed — a specific-sounding certification claim isn't automatically more trustworthy than a plainly described one. If you have questions about processing standards for a specific treatment, asking your physician directly during consultation is a reasonable, expected question. Full treatment detail is on our Stem Cell Therapy page, and published pricing for every stage described above is on our Pricing page.

Frequently asked questions

How long does the culturing and purification stage take?

Typically several weeks. Most patients return home during this window and come back to Tokyo once cells are ready for administration.

What happens if a batch of cells doesn't pass quality checks?

Only cells confirmed sterile and genetically stable are released for use — this is the specific purpose of that checking step, not a formality.

Is the cell-processing facility certified?

We describe our processing conditions as controlled, clean-room conditions. We don't claim a specific third-party facility certification or a named partner facility unless that relationship has been independently confirmed.

Is the infusion itself painful or invasive?

The infusion is delivered intravenously, similar to any standard IV procedure. Your physician reviews the specific risk profile relevant to your case before you consent.
