Kit Containing Stem Cells and Cytokines for Use in Attenuating Immune Responses

Stem cells have two distinct characteristics that distinguish them from other cell types. First, they are unspecialized and can self-renew for long periods without significant changes in their general properties. Second, under certain physiologic or experimental conditions, stem cells can be induced to differentiate into various specialized cell types. Thus, stem cells hold great promise for regenerative medicine. There are two major types of stem cells: embryonic stem (ES) cells and adult stem cells. Adult stem cells exist in many types of mature tissues such as bone marrow, muscle, fat, and brain.
