Ever since stem cells began being used for injury healing and recovery, people have asked about donor cells. It’s a question that has merit, and the implications, at least at first, seem to be positive. However, there are reasons why donor stem cells aren’t used for regenerative therapy, and at Greater Austin Regenerative Medicine & Wellness, we only use cells that are aspirated and collected from the patient’s own bone marrow. In this blog, we’ll cover some of the reasons why doctors don’t use donor cells, and hopefully some of your questions surrounding stem cells will be answered.

Donor Cells Don’t Meet FDA Standards

The Food and Drug Administration (FDA) is responsible for the protecting public health through the “safety, efficacy, and security of human and veterinary drugs, biological products, and medical devices.” Stem cells would fall in the category of “biological products,” and donor cells don’t meet the FDA requirements for minimal manipulation. This means they would have to undergo further safety testing, and may have to be classified as a “drug,” which would require even more thorough testing. If this were to happen, securing donor cells for use on humans could become very difficult, not to mention expensive.

Questions About Safety

One of the main concerns surrounding donor stem cells is safety. With organ and tissue transplantation from one person to another, there are often anti-rejection drugs that must be administered after the surgery. This is to help the recipient’s body accept the foreign organ or tissue, and avoid problems that can lead to more serious health problems. For example, if someone receives a kidney from a donor, even one that matches, there is still the risk of rejection. With donor stem cells, the same fear is present, and the rejection of these stem cells could create serious issues.

Sterile Processing

Donor stem cells, if used, would have to be thoroughly sterilized after being gathered. This process can significantly impact the cells’ viability, which could completely defeat the purpose of using them. If they’re unable to perform their regenerative processes, the recipient will basically be at the same stage they were before treatment. The FDA has recalled some donor stem cells because of their lack of sterility.

The Right Formulation

We’ve covered the types of stem cells found in bone marrow, and if the donor stem cells aren’t the right formulation (such as those needed for tissue regeneration) then their efficacy will be severely reduced. Some donor stem cells, such as those from adipose fat, have not shown to be as effective in regenerating bone formation. This of course completely defeats the purpose of stem cell therapy.
