Serum-Free Cultivation of Primate Embryonic Stem Cells


INVENTORS -

James Thomson

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing methods for stably culturing primate embryonic stem cells in serum-free media.
OVERVIEWAll known media for the stable cultivation of embryonic stem cells (ES cells) require serum; however, batches of fetal bovine serum vary dramatically in their ability to support ES cell growth. Cloning efficiency is approximately ten-fold higher in serum-free media, but cells in these media differentiate in seven to ten days.
THE INVENTIONA UW-Madison researcher has developed methods for stably culturing primate embryonic stem cells in serum-free media. The researcher discovered that adding basic fibroblast growth factor (bFGF) to serum-free media allows undifferentiated ES cells to proliferate in culture for long periods of time.
APPLICATIONS
  • Culturing primate ES cells
KEY BENEFITS
  • Allows stable proliferation for over one year
  • Cells maintain ability to differentiate into all cell types.
  • Supports clonal derivation at a higher efficiency than serum-containing media
  • No animal serum required
