a Attached cell densities over two passages for the three different donor cells, 1409, 1201 and 1412 grown in bioreactors. b Harvesting efficiencies for the three different donor cells between passages and after the final passage for expansion in bioreactors using the improved harvesting procedure. Error bars represent standard error of the mean. Statistical significance compares Donor 1201 and 1412 each to Donor 1409
