A stem cell is an extraordinary type of cell that has the ability to self-renew for
long periods of time and to differentiate into specialized cells under appropriate physiological or experimental conditions. Traditionally, stem cells have been classified as either embryonic, adult (tissue-specific or cord blood) stem cells. Recent understanding of stem cell biology may provide new approaches for the treatment of a number of diseases as well as tissue/organ injuries, including cardiovascular disease, neurological disease, musculoskeletal disease, diabetes and hematopoietic disorders. Stem cell fate is determined by both intrinsic regulators and the extra-cellular environment (niche), and their expansion and differentiation ex vivo are generally controlled by growing them in a specific configuration (monolayer or three-dimensional culture). This process, which is vital to enable stem cells to be used for therapeutic purposes, is called differentiation. Differentiation is a process involving unspecialized cells progressing to become specialized cells with restricted developmental potential. The purpose of this TriMark Publications report is to describe the specific market segments of the medical research space using stem cells for research and development (R&D) purposes. This study reviews all of the generally accepted analytical methods that are currently in use today for preparing and using stem cells. It examines the use of stem cells in developing new therapies for disease.
