IM-12

IM-12 is a cell-permeable indolylmaleimide that acts as a Glycogen synthase kinase 3 beta (GSK-3 beta) inhibitor, activating downstream components of canonical Wnt signaling. IM-12 significantly increases beta-catenin levels. IM-12 leads to TCF-induction and promotes neuronal differentiation in human neural progenitor cells by activating Wnt pathway. IM-12 when combined with other small molecules supports the self-renewal of naive human embryonic stem cells and maintenance of ground state pluripotency.
