Pyrintegrin is a cell-permeable small molecule that promotes human embryonic stem cell (hESC) survival by > 30-fold. Pyrintegrin can enhance cell-ECM adhesion-mediated integrin signaling. It can also stabilize the cell surface protein E-cadherin after cell dissociation.

How to Use:

• In vitro: Pyrintegrin was used at 3-5 µM concentration in cell culture.
• In vivo: n/a
