Each part of the human body has its own specific type of stem cells. For example, blood cells originate from stem cells (hematopoietic cells). They are in every adult person and are in the bone marrow. However, their stock is relatively small and, unfortunately, in many cases, the body is not able independently regenerate the lost cells. For example, when the body is weakened (by virus, harmful bacterium, etc.), the area of damage is very big. This is also true for elder people. However, transplanting millions of stem cells allows you to repair damaged tissues.
Stem cells collection
For stem cells collection the patient are connected to the apheresis device. It divides blood into various components and collects stem cells. This procedure does not cause anemia and lasts 4-6 hours.
Cultivation and freezing
Collected stem cells are delivered to the stem cell laboratory. There, the number of cells is determined, the correlation of cells and plasma is corrected, divided into doses for transplantation and frozen (-150 °C).
Transplanted stem cells are moved from the bloodstream to the bone marrow, where new red blood cells, leukocytes and platelets start to produce. New cells enter the bloodstream after 10-14 days.
Within 2-3 weeks after transplantation, the adoption process by the body occurs. During this process, the immune system of the body is weakened, therefore, it is necessary to stay in the special conditions of the hospital.
