GSK-3 Inhibitor

1

　CHIR 99021 (1) is a cell-permeable and highly selective GSK-3 inhibitor¹⁾ and inhibits GSK3α (IC₅₀=10 nM) and GSK3β (6.7 nM).²⁾ 1 is also used as a key component for mouse embryonic stem cell self-renewal.³⁾ Under cytokine-free conditions, the combination of 1 and the mTOR inhibitor, rapamycin, maintains mouse and human hematopoietic stem cells.⁴⁾ In the presence of 1, OCT4-transduced human blood CD34⁺ cells are converted into induced mesenchymal stem cells (iMSCs).⁵⁾

The product is for research purposes only.
