Stem Cell Collection for Transplantation

Hematopoietic stem cells are the primary cells of the blood-forming system, from which all blood elements originate. Under normal conditions, they reside in the bone marrow; however, following administration of specific mobilizing agents, they temporarily enter the peripheral bloodstream. At this stage, stem cell collection from peripheral blood is performed.

 Stem cell transplantation is widely used for the treatment of various hematological and oncological diseases. 

The procedure is similar for both allogeneic and autologous transplantation. In autologous transplantation, the patient serves as their own donor, whereas in allogeneic transplantation, the donor is another individual.

The collection process is carried out using specialized equipment: the required cells are separated from the blood, and the remaining components are returned to the patient’s circulation. The procedure typically lasts several hours and is performed under continuous medical supervision.

Collected stem cells may be used immediately or cryopreserved under specialized conditions for future transplantation.

 Stem cell collection is performed at the “Yolyan” Hematology and Oncology Center.

 The introduction of this method, along with bone marrow transplantation, represents a significant advancement for healthcare in Armenia.

 In modern medicine, stem cell collection and preservation enable more effective treatment and significantly improve patients’ chances of recovery.
