From: Two-dimensional material-based bionano platforms to control mesenchymal stem cell differentiation
The osteogenic differentiation of human mesenchymal stem cells (hMSCs) induced by electrical release of differentiation factor, dexamethasone (DEX). (a) Schematic diagram represents the fabrication process of DEX-loaded bioelectrode array. (b) Immunofluorescence images of OCN expression in hMSCs cultured on various sizes of rGO-PEDOT (rGO-PEDOT-20, rGO-PEDOT-50, and rGO-PEDOT-100). (c) Schematic representation for rGO-PEDOT behavior.
