Currently, fetal bovine serum (FBS) is the most widely used growth factor supplement for the expansion of human cell therapy products. However, there has been a strong impetus from regulatory agencies and biomedical professionals in the field to develop methods for cell expansion that do not utilize animal products in their production process.1 Human platelet lysate (hPL) has been identified as a possible growth supplement contender—rich in growth factors and produced in most cases from expired platelets (PLTs)—that can be used to replace FBS.
