Biological Activity for Chroman 1
Chroman 1 is a highly potent and selective ROCK2 inhibitor (IC50 values are 1 and 52 pM at ROCK2 and ROCK1, respectively). Exhibits selectivity over a range of related kinases including PKA, AKT1 and MRCK (IC50 values are >20000, >20000 and 150 nM respectively). Improves cell survival after cryogenesis. Also promotes survival of stem cells in culture.

Stem Cells Scientific Review
Written by Kirsty E. Clarke, Victoria B. Christie, Andy Whiting and Stefan A. Przyborski, this review provides an overview of the use of small molecules in the control of stem cell growth and differentiation. Key signaling pathways are highlighted, and the regulation of ES cell self-renewal and somatic cell reprogramming is discussed. Compounds available from Tocris are listed.
Stem Cell Workflow Poster
Stem cells have potential as a source of cells and tissues for research and treatment of disease. This poster summarizes some key protocols demonstrating the use of small molecules across the stem cell workflow, from reprogramming, through self-renewal, storage and differentiation to verification. Advantages of using small molecules are also highlighted.
Stem Cells Poster
Written by Rebecca Quelch and Stefan Przyborski from Durham University (UK), this poster describes the isolation of pluripotent stem cells, their maintenance in culture, differentiation, and the generation and potential uses of organoids.
