- StemRegenin 1 (SR1) | Promote CD34+ cell expansion
Product Description
The compound StemRegenin 1 (SR1) is a selective, cell permeable, small molecule that promotes the self-renewal of human hematopoietic stem cells in culture. SR1 is an antagonist of the aryl hydrocarbon receptor.
SR1 is the first small molecule that promotes robust expansion/self-renewal of human CD34+ peripheral blood and cord blood hematopoietic stem cells (HSCs). Culture of HSCs with SR1 led to a 50-fold increase in cells expressing CD34 and a 17-fold increase in cells that retain the ability to engraft immunodeficient mice. SR1 can be potentially used for ex vivo expansion of normal HSCs or leukemic stem/progenitor cells.
