Scientists rid stem cell culture of key animal cells

...n use. Until now, scientists have had to grow and sustain stem cells through the tedious daily task of generating mouse feeder cells from mouse embryos. Feeder cells, or fibroblasts, are connective tissue cells that form the matrix upon which stem cells grow. The mouse feeder cells were an important ingred...
