[PAR] [TLE] Benjamin Alman [SEP] Benjamin Alman, MD, FRCSC, was the head of the division of Orthopedic surgery at the Hospital for Sick Children in Toronto, Ontario, senior scientist in developmental and stem cell biology at Sick Kids, and vice chair of the department of surgery at the University of Toronto.  He has given many speeches and lectures throughout the world, and has won many awards and prizes, including the Premier’s Research Excellence Award, the Huene Award, the OREF Research Award, and the Royal College Medal in Surgery.  .  As of June 1, 2013, he is the head of Orthopedics at Duke University Medical School in Durham, North Carolina. [PAR] [TLE] Stem cell [SEP] 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.
