StemRegenin 1 (SR1)

SKU: orb1226741

Description

StemRegenin 1 is an aryl hydrocarbon receptor (AhR) inhibitor with IC50 of 127 nM in a cell-free assay.(In Vitro):StemRegenin 1 (SR1) acts by antagonizing the aryl hydrocarbon receptor (AhR). StemRegenin 1 increases the number of CD34+ cells after 5 to 7 days with an EC50 of ~120 nM. StemRegenin 1 inhibits photoaffinity ligand (PAL) binding (IC50=40 nM) These results support the conclusion that StemRegenin 1 -induced CD34+ cell expansion is mediated through direct binding and inhibition of the AhR. An aryl hydrocarbon receptor antagonist, StemRegenin 1 (SR1), robustly promotes ex vivo expansion of human CD34+ cells. StemRegenin 1 treatment accelerates the proliferation of CD34+ cells and decreases the expression levels of VentX.
