General description

A cell-permeable indolopyridine compound that acts as a selective, reversible, and ATP-competitive inhibitor of Rho kinase activity with an IC50 of 25 µM. Does not inhibit the activation of Rho kinase nor does it affect the in vitro activities of MLCK, PKCα, and SAPK2a/p38α. Shown to be 5-fold less potent than Y-27632 (Cat. No. 688000; IC50 = ~5 µM), and display a similar specificity profile as H-89 (Cat. No. 371963). Affects cell migration, inhibits blebbing (IC50 = ~ 12 µM in M2 cells), and decreases stress fibers in Bulb 3T3 cells at 50 µM.

T cells in vivo migrate primarily via undirected random walks, but it remains unresolved how these random walks generate an efficient search. Here, we use light sheet microscopy of T cells in the larval zebrafish as a model system to

The assembly of the embryo's primary axis is a fundamental landmark for the establishment of the vertebrate body plan. Although the morphogenetic movements directing cell convergence towards the midline have been described extensively, little is known on how gastrulating cells

Membrane curvature recruits Bin-Amphiphysin-Rvs (BAR)-domain proteins and induces local F-actin assembly, which further modifies the membrane curvature and dynamics. The downstream molecular pathway in vivo is still unclear. Here, we show that a tubular endomembrane scaffold supported by contractile actomyosin stabilizes
