The purpose of these studies was twofold: to reduce the level of nonhuman, potentially immunogenic sialic acid N-glycolylneuraminic acid (Neu5Gc) in human embryonic stem cells (hESCs) through culture of the cells in the absence of feeder layers; and to determine whether directed differentiation was preserved under these conditions, that is, using exclusively human-derived products.
