Before these clearances, platelets had been limited to a shelf life of five days before expiration due to the risk of bacterial contamination.
These new product clearances allow the extension of platelet dating when platelets stored in these containers are tested with a bacterial detection device labeled as a "safety measure.
Blood cells, such as platelets, are made in bone marrow.
Bioreactor-derived platelets theoretically have several advantages over conventional, donor-derived platelets in terms of safety and resource utilization," said William Savage, MD, PhD, medical director, Kraft Family Blood Donor Center at Dana Farber Cancer Institute/Brigham and Women's Hospital, who did not contribute to the study.
Platelets are tiny cells in the blood which help to stem blood loss by enabling clotting and can be used to help cancer or leukaemia sufferers undergoing chemotherapy or patients with certain types of anaemia.
Reticulated platelets have clinical utility because they can help distinguish bone marrow failure from peripheral destruction in thrombocytopenia.
It has been postulated that the use of SDP instead of pooled platelets would decrease donor exposures and thus reduce the risks of infection and alloimmunization.
11-13) If platelets are being destroyed in the periphery, then platelet production by the healthy bone marrow increases in kind, resulting in high levels of immature platelets circulating in the blood.
Platelets play an important role in thrombus formation in injured blood vessels.
The inclusion of bacteria-derived ristoce-tin is motivated since it stimulates the otherwise flow-dependent interaction between von Willebrand factor (vWf) and gly-coprotein (GP)-Ib-IX-V on platelets (19).
Thrombocytopenia is the medical term for having too few platelets (also called thrombocytes), a clotting agent in blood.
The physiology of platelets has been reviewed extensively elsewhere (13-15) and only a brief summary is provided here.
