Co-culture of mesenchymal-like stromal cells derived from human foreskin permits long term propagation and differentiation of human embryonic stem cells.

Among the different parameters governing the successful derivation and expansion of human embryonic stem cells (hESC), feeder layers play the most important role. Human feeders in form of human mesenchymal stromal cells (hMSCs) and human foreskin fibroblasts (HFFs) lay the foundation for eradication of animal-derived hESC culture system. In this study we explored the potential of human foreskin derived mesenchymal like stromal cells (HF-MSCs) to support self renewal and pluripotency of hESC.
