Cell count loss during final drug product manufacturing from cryopreserved drug substance aliquots. a Cell count loss shown by tissue donor. b Cell count loss shown by lab assistant. Cell count loss is expressed as percentage difference between the expected (as calculated from the number and the cell content of the aliquots) and the actual final cell count. Shown are means ± SD of n manufactured products; blue dotted lines indicate mean cell count loss of all 85 produced drug products. Note that the letters A–K identifying the lab assistants are arbitrarily assigned based on the order of data arrangement and do not match with those used in Fig. 3
