Human induced pluripotent stem cell culture on polyvinyl butyral-based substrate compared with other synthetic chemical substrates. (A) 253G1 and 201B7 colony morphology on PVB, PVA, PEGMA and PNIPAM in TeSR-E8 medium. 253G1 cells show the state on day 4, and 201B7 cells show the state on day 7. TeSR-E8 medium was used for both. (B) 253G1 colony morphology on CPB scaffold during five days in TeSR-E8 medium. All scale bars are 200 µm.
