Wachstumsfaktoren für die Kultivierung induzierter pluripotenter Stammzellen

The use of induced pluripotent stem cells (iPSCs) in research has completely changed regenerative medicine and accelerated the research process of human diseases. The unique self-renewal characteristics and gene engineering editing ability of iPSCs can generate an almost infinite number of mature differentiated cell types, including immune cells (T cells, NK cells, macrophages, etc.), neurons, pancreatic islet cells, etc.
ACROBiosystems focuses on supporting research and CMC manufacturing process related to cell therapy. With a comprehensive cell culture platform, antibody development platform, flow cytometry validation platform, and GMP quality management system, We have developed a series of CMC production process related products for iPSCs, helping customers accelerate the production process and fully supporting the development process based on iPSC therapy.
