Live and dead assay of the cell-encapsulated cross-linked hydrogel samples at Day 0, 3 and 7 and H & E Day 7: (A) GelMA, (B) CNP + GelMA, (C) CNP GelMA, all samples (30% w/v) are mixed with Irgacure 2955 (5% w/w) and cross-linked with UV exposure during bioprinting. 0.5 million/ml AdMSC cells were mixed with GelMA/Irgacure solution and bioprinted before crosslinking (UV treatment). D ALP activity, (E) Gene expression study (RT-µPCR Day 8)
