Human induced pluripotent stem cells (hiPSCs) are considered as a promising tool in medicine, with the potential to unlock treatments for many health conditions such as neurodegenerative diseases and disorders. However, producing large amounts of hiPSCs remains a challenge. Researchers from the Fraunhofer Translational Center for Regenerative Therapies TLC-RT at the Fraunhofer Institute for Silicate Research ISC have now developed a bioreactor that can be used for automated long-term culturing of hiPSCs.
