Research with ES・iPS Cells

  • The efficiency of the selective ROCK inhibitor Y-27632 in ES・iPS cells has been demonstrated by several studies.
  • Bulk orders are welcome.

Y-27632 is a highly potent, cell-permeable, and selective ROCK inhibitor. As well as modulating smooth-muscle contraction by inhibiting Ca2+ sensitization, the Rho/ROCK pathway may help to regulate integrin-mediated cell adhesion and motility.
Furthermore, it inhibits the cell death of human ES and iPS cells at cell dispersion. The colony forming activity of cryopreserved human ES and iPS cells thawed and cultured in a medium comprising Y-27632 was significantly improved.
