I. Introduction A. Attention getting opener: There is a critical need for effective, long-term solutions for harvesting stem cells. Already there are "more than 300,000 units stored worldwide. These products have been banked under stringent quality conditions, in order to ensure their safety and efficacy," (Vladareanu, Mihailescu & Zvanca, 20070, p. 142). B. Credibility statement: Abundant research shows that harvesting stem cells from umbilical cord blood offers crucial advantages over other methods, including bone marrow and peripheral blood. C. Thesis: Although not an ideal medium for harvesting, and will not replace other types of stem cell sources, umbilical cord blood should be an integral part of the blood/tissue bank repertoire. II. Advantages of using umbilical cord blood. A. Immunology 1. "Umbilical cord blood (UCB) contains stem and progenitor cells capable of restoring haematopoietic and immunological function in vivo," (Navarette & Contreras, 2009, p. 236). 2. Umbilical cord blood stem cells "can be transplanted to regenerate a patient's immune system," (Vladareanu, Mihailescu & Zvanca, 20070, p. 142). B. Pre-frozen/cryopreservation 1. cryopreservation allows for the storage of stem cells for future use, eliminating need for searching for suitable donor 2. Especially true when minorities need transplants (Samuel, et. Al, 2007). C. Advantages over other forms of stem cell 1. Bone marrow cell harvesting "may be detrimental due to the
