StemRegenin 1

Key Product Details

Product Description

StemReginin 1 is an aryl hydrocarbon receptor (AHR) antagonist (IC₅₀ = 127 nM). StemReginin 1 exhibits no inhibitory activity against a panel of 61 kinases and preferentially inhibits human AHR. StemReginin 1 promotes the expansion of CD34+ cells ex vivo. In hematopoietic stem cell (HSC) culture, the compound induces a 50-fold increase in CD34-expressing cells, and HSCs cultured with StemReginin 1 show increased engraftment in mice. Combination of StemReginin 1 with DMOG (Cat. No. 4408) increases the proportion of primitive HSCs and improves long-term engraftment. The product also promotes expansion of human promyelocytic leukemia cell line NB4.
