Abstract
After completing this article, readers should be able to: 1. List the three cells from which mouse pluripotential stem cells can be derived. 2. List the types of specific cells that have been differentiated from murine embryonic stem cells in laboratory investigations. 3. Delineate the potential methods of using human stem cells to minimize immunologic rejection after transplantation. 4. Describe some of the issues requiring resolution before human stem cells can be used in therapies. The dream of one day being able to provide an unlimited supply of human tissues for transplantation came one step closer 2 years ago when two teams of scientists from Johns Hopkins University and the University of Wisconsin announced the successful derivation of human pluripotential stem cells (PSCs). This research immediately caught the public’s eye because of its enormous impact on transplantation therapies and the sources of tissues. Human stem cells are renewable in culture and are capable of differentiating into a wide variety of tissue types. The unlimited ability to divide and the capability to form into almost every cell type provide the source of replacement cells for transplantation and raise the hopes of numerous patients who have debilitating conditions, such as Parkinson disease, Alzheimer disease, stroke, and type I diabetes. Human stem cells will be important for in vitro studies of human gene discovery, for pharmaceutical research such as drug toxicology studies for screening and testing, and as a renewable source of cells for tissue transplantation and gene therapies. In addition to clinical applications, human stem cells provide a powerful tool for biomedical research into human embryogenesis, specific gene functions, and lineage development. PSCs, primarily embryonic stem (ES) cells, have been used extensively in studies of embryogenesis, gene function, and development in the mouse. Present in the early stages of embryo development, PSCs can generate all of …
