Stem Cell Expansion

In order for stem cells, or even fully differentiated cell populations to be truly beneficial or useful, either therapeutically, as drug screening tools, or for core research purposes, expansion of cells is prerequisite. An appropriate culture environment is critical to stem cell expansion efforts. This environment is typically maintained by a combination of media, supplements, and reagents and may or may not involve the need for healthy feeder populations or conditioned media taken off feeder cells. This section contains products for effective expansion of stem cells from a variety of sources. The products listed in this section are our most commonly used. Other, more unique products may also be found throughout the Sigma-Aldrich website.
