The Stem Cell: " Its Revolutionary Impact & Controversy "

(Häftad)
Beskrivning:

Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cells-ectoderm, endoderm and mesoderm (see induced pluripotent stem cells)-but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.There are three known accessible sources of autologous adult stem cells in humans:1.Bone marrow, which requires extraction by harvesting, that is, drilling into bone (typically the femur or iliac crest).2.Adipose tissue (lipid cells), which requires extraction by liposuction.3.Blood, which requires extraction through apheresis, wherein blood is drawn from the donor (similar to a blood donation), and passed through a machine that extracts the stem cells and returns other portions of the blood to the donor.Stem cells can also be taken from umbilical cord blood just after birth. Of all stem cell types, autologous harvesting involves the least risk. By definition, autologous cells are obtained from one's own body, just as one may bank his or her own blood for elective surgical procedures.This book discusses the latest information on the biology and use of stem cells and is designed to be a state of the art, superb academic reference work and provide an overview of the topic and give the reader a structured knowledge to familiarize yourself with the topic at the most affordable price possible.The accuracy and knowledge is of an international viewpoint as the edited articles represent the inputs of many knowledgeable individuals and some of the most current knowledge on the topic, based on the date of publication.
