Selected Annotated Bibliography on Stem Cell Research and Cloning
Abstract
More questions than answers exist surrounding the powers and potential of stem cells. A great deal of uncertainty abounds about both embryonic and adult stem cells, much of which has been furthered by a flurry of recent publications and a loose set of definitions. Rigorous definitions in stem cell research are necessary; a true stem cell must satisfy the following criteria:
1. It must be clonogenic, capable of unlimited self-renewal by symmetric division.
2. It must be able to divide asymmetrically, one daughter resembling its mother, the other daughter giving rise to multiple types of differentiated cells representing all three primitive embryonic germ layers (the ectoderm, mesoderm, and endoderm).
3. It must originate from an embryonic or adult stem-cell source.
