Scientists at UCLA have developed what they claim is a fully chemically defined, animal-free alternative to standard mouse feeder cell- and bovine sera-containing culture systems for human embryonic stem cells (hESCs). They claim their new culture system represents a genuinely scalable single-cell passaging system for the long-term propagation and maintenance of hESCs that will help address what could otherwise represent significant regulatory and cGMP-related stumbling blocks for the future transfer of stem cell-based regenerative therapies from the lab to the clinic and commercial arena.
