Collagen IV outperforms alternative ECM coatings to preserve human neural progenitor properties on electrically conductive neural interfaces (opens in new tab)

Human neural progenitor cells (hNPCs) are promising candidates for neural repair, however, their in vitro expansion commonly relies on Matrigel, a tumor-derived and xenogeneic matrix that limits translational applicability. In this study, we evaluated defined extracellular matrix (ECM) coatings, including poly-L-ornithine (PLO), laminin, PLO/laminin, and collagen IV, as alternatives to Matrigel for hNPC culture under conventional and electrically stimulated conditions. We found that collagen ...
