General description

A 5 mM (500 µg/296 µl) aqueous solution of Y-27632 (Cat. No. 688000). A highly potent, cell-permeable, selective inhibitor of Rho-associated protein kinase (Ki = 140 nM for p160ROCK (ROCK-I). Also inhibits ROCK-II with almost equal potency. Inhibition is achieved by competing with ATP for binding to the catalytic site. Exhibits 10- to 50-fold lower affinity for PKCε than p160ROCK. Does not affect the activity of p21-activated protein kinase (PAK) even at high concentrations (~100 mM). Also acts as a potent inhibitor of agonist-induced Ca2+ sensitization of myosin phosphorylation and smooth muscle contractions (IC50 = 700 nM for phenylephrine-induced contractions in aortic strips).

Once human photoreceptors die, they do not regenerate, thus, photoreceptor transplantation has emerged as a potential treatment approach for blinding diseases. Improvements in transplant organization, donor cell maturation, and synaptic connectivity to the host will be critical in advancing this

Nephrons differentiate from the cap mesenchyme of the fetal kidney. Nephron progenitor cells that populate the cap mesenchyme efficiently balance self-renewal and epithelial differentiation to enable repeated rounds of nephron formation during development. Here we describe a method to isolate
