Changing the Cell Source in Cell Therapy?

One dream of scientists is to be able to rebuild, in vitro, “spare parts” to replace injured or diseased tissues — a notion that was once relegated to the realm of science fiction. The concept that stem cells that are ostensibly site-specific can give rise to (and maintain) mature tissues has made adult stem cells the focus of intense research designed to explore their promise for the treatment of a variety of human diseases.Adult stem cells are defined as clonogenic, self-renewing progenitor cells that can generate one or more specialized types of cells. However, major obstacles in this field . . .
