Protocols for maintenance of hPSCs and generation of lung cells were slightly modified from previous studies (Chen et al., 2019; Huang et al., 2014). The hESC line-RUES2 was cultured on irradiated mouse embryonic fibroblasts (Global Stem, cat. no. GSC-6001G) at a density of 20,000-25,000 cells/cm2 in a medium of DMEM/F12, 20% knockout serum replacement (Life Technologies ), 0.1 mM β-mercaptoethanol (Sigma Aldrich) and 20 ng/ml bFGF (R&D Systems), and medium was changed daily. hESC cultures were maintained in an undifferentiated … Continue reading „MCDB 131 W/O L-Glutamin“
