Thermo Fisher Scientific Inc. introduced the Thermo Scientific HyClone HyCell-STEM and HyCell-STEM-FF stem cell culture media, designed to optimize the expansion rate of human embryonic stem cells (hESCs) and induced pluripotent stem cells (hiPSCs) per passage for cell culture applications including cell signaling, drug discovery and therapeutic research. HyCell-STEM is designed for use with stem cells on feeder layer cultures, and HyCell-STEM-FF is designed for stem cells in feeder-free conditions. Both products offer an increased expansion rate compared to market competitors based on internal testing, yielding as many as twice the cells on every passage. The media systems require no adaptation and hESCs and iPSCs can be thawed or seeded directly into the systems. Additionally, robust hESCs and iPSCs grown in HyCell-STEM do not have to be fed daily, saving time, resources and weekend demands for researchers. For feeder-free culturing with the HyCell-STEM FF, the need of feeder cells is eliminated entirely, and stem cell culture preparation is simplified. Other key features and benefits of the media systems include:

• Optimized expansion rate of human embryonic stem cells (hESCs) and induced pluripotent stem cells (hiPSCs) per passage
• Healthy stem cell morphology demonstrated by tight clustering and smooth borders of cultured cells
• Preservation of stemness and pluripotency over multiple passages
• Superior post-thaw recovery of stem cells from cryopreservation with cells thawed directly in the systems, yielding more cells faster
