Neural priming of adipose-derived stem cells by cell-imprinted substrates.
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 substrates on fixed differentiated neural progenitor cells (ReNcellTM VM). The ReNcellTM cell line consists of immortalized human neural progenitor cells that are capable to differentiate into neural cells.
