Figure 1. Morphology of iPSCs.
(A) iPSCs were grown in KSR complete medium with KnockOut™ SR Growth Factor Cocktail on Geltrex™-coated dishes; cells exhibited morphology similar to hESCs, characterized by large nuclei and scant cytoplasm. (B) iPSCs were grown in KSR XF complete medium with KnockOut™ SR Growth Factor Cocktail on Geltrex™-coated dishes; cells exhibited morphology similar to hESCs, characterized by large nuclei and scant cytoplasm.
Figure 2. Pluripotent marker expression of iPSCs.
Immunostaining of iPSCs for the expression of pluripotent marker OCT4 cultured on KSR medium with KnockOut™ SR GF Cocktail. Green color indicates Oct4 expression; blue color represents DAPI nuclear staining of the same field.
Figure 3. Morphology of hESCs in a feeder-free culture.
BG01V cells were cultured under feeder-free conditions, using KnockOut™ SR XenoFree directly with KnockOut™ SR GF Cocktail on CELLstart™ Matrix in Knockout™ DMEM. At passage 15, BG01V cells were cryopreserved in the same medium and placed in liquid nitrogen storage. Photos show attachment and growth of BG01V when cryopreserved cells were recovered in feeder-free KnockOut™ SR XenoFree Medium, from day 1 (A) through day 3 (B) post thaw.
