In vitro megakaryocyte production and platelet biogenesis: state of the art.
The exciting and extraordinary capabilities of stem cells to proliferate and differentiate into numerous cell types not only offers promises for changing how diseases are treated but may also impact how transfusion medicine may be practiced in the future. The possibility of growing platelets in the laboratory to some day supplement and/or replace standard platelet products has clear advantages for blood centers and patients. Because of the high utilization of platelets by patients undergoing chemotherapy or receiving stem cell transplants, platelet transfusions have steadily increased over the past decades. This trend is likely to continue as the number of adult and pediatric patients receiving stem cell transplants is also continuously rising. As a result of increased demand, coupled with the short shelf-life of platelet concentrates, providing platelets to patients can stretch the resources of most blood centers and drive donor recruitment efforts, and on occasion, platelet shortages can compromise the care of thrombocytopenic patients.
