Clinical trials are research studies performed on people that are aimed at evaluating a medical, surgical, or behavioral intervention. They are the primary way that researchers find out if a new treatment, such as a new drug, is safe and effective in people.
Autologous stem cell treatments use cells derived from the patient's own body. In practice, this often involves extracting MSCs from the fat tissue and injecting the patient with a concentrate including stem cells from the fat. This treatment option is widespread today since it is not classified as a medicinal product. This however also means that there is no control from medical authorities such as EMA and FDA.
Allogeneic stem cell treatments use the cells obtained from a donor.
There are various advantages with allogeneic MSC treatments produced by companies that follow the EU or US regulations. The quality is strictly regulated and controlled, meaning that we can be certain that the patient receives the intended amount and potency of cells. There is data indicating that MSCs from younger people are more potent than from older ones. One donor can provide enough cells to more than 100 patients.
