The authors of this study show that fibroblast feeders synthesize laminin-511 and that this is the main protein responsible for the maintenance of hESC pluripotency. This strengthens the already known biological function of laminin-511 and laminin-521 as the main cell-adhesion molecules for pluripotent stem cells.
