Autologous means the cells come from you. Allogeneic means they come from somebody else. The distinction sounds academic until you notice that it decides almost everything about how cells are produced, who they are produced for, and what the research on them is actually describing. One is made for a single person. The other is made once and divided among many. American Cell Technology is autologous only, and what follows is what the two words mean in practice, why nearly all the published research you will find is built on donor cells, and what it changes to have your own cells banked.
Cells made for one person, or cells made for many
Autologous cells are collected from a person and prepared for that same person, so every batch exists for one recipient and cannot be used for anyone else. Allogeneic cells come from a donor, and because a donor sample can be grown into a large lot, one collection can supply many recipients (BioProcess International, 2024).
| Autologous | Allogeneic | |
|---|---|---|
| Source of the cells | You | Another person |
| DNA | Yours | The donor’s |
| Who a batch serves | One person | Many recipients |
| In banking | Collected from you and held in your name | Not what ACT banks |
That asymmetry carries through to everything downstream. A donor lot is produced once and sized for a population, while an autologous batch is produced for one person and sized by what was collected from them, which is why quantity and timing on the autologous side depend on the collection itself rather than on a production schedule. How the collection works covers what that involves.
Both words describe origin and scale. Neither tells you what the cells can do, and this page keeps that distinction in place.
Why most published research uses donor cells
Because it is easier to take one donor sample and expand it at scale than to bank and process every participant individually.
A donor sample can be expanded with scalable methods, banked, and divided across every participant in a trial, which is how most biologics are produced. A study built on each participant’s own cells has to run a separate production process for each person, and one published analysis put the manufacturing cost of an autologous dose at more than double that of an allogeneic one (BioPharm International).
This matters for how you read what you find. A study describing donor cells given under a protocol is describing a different arrangement from having your own cells banked, even when the cell type is the same.
What ACT banks for you
Your own cells, in your own name. In banking, the two words answer something narrow: whose cells these are, how many of them there are, and how long they stay in storage.
American Cell Technology collects a small sample of your adipose (fat) tissue or bone marrow through your physician, isolates the mesenchymal stem cells (MSCs) from it, multiplies them in culture, and banks them in vials of 10 million live cells. Clients own their cells, and ACT holds them as custodian. Release happens at your physician’s request. What happens to them after that is decided between you and your physician.
Is one better than the other?
The published literature does not settle it. A 2021 review of both approaches in clinical practice concludes that the therapeutic benefits of autologous compared with allogeneic MSCs are inconclusive, and that immunogenicity, donor variability and cell behaviour after administration are all still being investigated (Li et al., 2021).
That is an active research question, and it belongs with your physician rather than with a laboratory. What banking settles is something narrower and more immediate: whether your own cells exist, documented and in storage, before any of that comes up.
You are choosing whether to have your own cells banked. What is eventually done with them is decided by you and your physician. ACT works with some of the top physicians in the United States, and banking with ACT gives you access to that network.
Your banked cells carry your DNA because they came from you, so there is no donor to find and no match to confirm.
Each vial holds 10 million live cells, counted and confirmed before freezing. The live cell count is confirmed again after thawing and validated by our quality department before anything is sent.
The sample is held in your name rather than in a pool. Release happens at your physician’s request, on your timeline.

Frequently asked questions
Does ACT bank donor cells?
No. ACT banks adult cells collected from the person they are stored for.
Where do the cells come from?
From your own adipose tissue or bone marrow, collected by your physician in a short in-office procedure.
How long do banked cells last?
Cells held in liquid nitrogen at minus 196 degrees Celsius are metabolically stored in time. They have no metabolic activity, are dormant and do not age, which is why there is no limit on how long they can stay banked when they are cryopreserved properly.
Does my age affect whether this is worth doing?
Less than most people assume. Stem cell banking myths, and what is actually true covers what the telomere data shows.
What does it cost?
Two parties charge separately, your physician for the collection and ACT for stem cell processing, and what the processing fee covers, and what is billed separately sets out both sides.
