| Serum-Free Cultivation of Primate Embryonic Stem Cells |
| INVENTORS | • | James Thomson |
OVERVIEW
All 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 INVENTION
A 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
