General description

A cell-permeable compound that acts as a selective, potent, and reversible inhibitor of non-muscle myosin II. Inhibits the ATPase and gliding motility of human platelets (≤100 µM) without affecting myosin light chain kinase (MLCK) activity. Has been shown to block cell blebbing and to rapidly disrupt directed cell migration and cytokinesis in vertebrate cells. Does not disrupt mitosis or affect contractile ring assembly.

Biochem/physiol Actions

Cell permeable: yes
Primary Target
ATPase
Product does not compete with ATP.
Reversible: yes
Target IC50: <100 µM inhibiting the ATPase and gliding motility of human platelets

Packaging

Packaged under inert gas

Warning

Toxicity: Harmful & Carcinogenic / Teratogenic (E)

Physical form

A 50 mM (5 mg/342 µl) solution of (±)-Blebbistatin (Cat. No. 203390) in 90% DMSO.

Reconstitution

Following initial thaw, aliquot and freeze (-20°C).

Archetypal human pluripotent stem cells (hPSC) are widely considered to be equivalent in developmental status to mouse epiblast stem cells, which correspond to pluripotent cells at a late post-implantation stage of embryogenesis. Heterogeneity within hPSC cultures complicates this interspecies comparison.

Tissue homeostasis and disease states rely on the formation of new blood vessels through angiogenic sprouting, which is tightly regulated by the properties of the surrounding extracellular matrix. While physical cues, such as matrix stiffness or degradability, have evolved as

The mechanical properties of the extracellular environment are interrogated by cells and integrated through mechanotransduction. Many cellular processes depend on actomyosin-dependent contractility, which is influenced by the microenvironment's stiffness. Here, we explored the influence of substrate stiffness on the proteome

In solid tumours, the abundance of macrophages is typically associated with a poor prognosis. However, macrophage clusters in tumour-cell nests have been associated with survival in some tumour types. Here, by using tumour organoids comprising macrophages and cancer cells opsonized
