Human insulin-like growth factor 1 (IGF-1) protein is used in the maintenance of human pluripotent stem cells (IPSC) and is necessary for cell growth in the absence of insulin. IGF-1 promotes the proliferation of many cell types, including embryonic stem cells (ESC) and mesenchymal stem cells (MSC).

Qkine IGF-1 is a highly pure and bioactive 8 kDa protein, Qkine growth factors are animal origin-free (AOF) and carrier-protein free (CF) for consistent stem cell culture.
