Process- and bio-inspired hydrogels for 3D bioprinting of soft free-standing neural and glial tissues.

abstract：:Cell-imprinting technology is a novel method for directing stem cell fate using substrates molded from target cells. Here, we fabricated and studied cell-imprinted substrates for neural priming in human adipose-derived stem cells in the absence of chemical cues. We molded polydimethylsiloxane (PDMS) silicone substrate...
