Cells are the building blocks of life and some cells (stem cells) have the ability to produce other cells through the processes of cell division and cell differentiation. Stem cell research has now progressed dramatically and there are countless studies published every year in scientific journals. Stem cell technology is being used to create new cell lines with edited genes and to regenerate cell based tissues for biological and medical purposes. This ebook presents a brief snapshot of clinical research in stem cell research and regenerative medicine. The concise reference is intended to be an introduction for biology students to current standards and new technologies in these field.
