The expansion of stem cell numbers while retaining their developmental properties is a bioprocess challenge. We compared the growth rates and embryoid body (EB) formation yields of R1 and EFC murine embryonic stem cells (mESC) cultured in two basal media (DMEM or DMEM:F12) with additions of 1.7-15% fetal bovine serum (FBS) or serum replacer (KOSR). Whereas the basal medium or KOSR dose did not have a significant effect on growth rate for either cell line, increasing doses of KOSR had a significant negative effect on the EB yield of EFC cells. Use of DMEM:F12 and increasing doses of FBS independently and significantly increased the growth rate for both cell lines. DMEM:F12 also significantly increased EB yields for both cell lines. The results show that use of DMEM:F12 and several-fold lower than conventional concentrations of KOSR can efficiently support maintenance of mESC and that KOSR should be dose as well as lot optimized.
