Mechanisms of Mineralization of Vertebrate Skeletal and Dental Tissues (PDF)

Irving M. Shapiro, B.D.S., M.Sc., Ph.D., is the Gertrude and Anthony DePalma Professor of Orthopaedic Surgery and Vice-Chair (Basic Science) in the Department of Orthopaedic Surgery in the Sidney Kimmel Medical College of Thomas Jefferson University, Philadelphia, USA. Dr. Shapiro earned his dental qualifications from the (Royal) London Hospital and received the degree of Ph.D. from the University of London. During his career, Dr. Shapiro has authored over 350 publications, co-edited four books, including The Intervertebral Disc, chaired two Gordon Conferences, and co-chaired meetings on the Growth Plate and the Spine. His investigations of the growth plate have lent new understanding to the basic mechanisms responsible for bone growth, as well as the role of ionic constituents, local nutrition, and oxygen tension during the maturation of cells of growth plate cartilage. More recently, his studies have focused on the intervertebral disc and events that lead to its degeneration. He established the importance of hypoxia inducible factor in maintenance of disc cell function and signaling pathways involved in the conservation of osmotic pressure in the disc. Continuing work initiated at the University of Pennsylvania, he created a class of new antimicrobial surfaces for use in joint replacement therapy and very recently, working collaboratively, he has helped to define new approaches to combat septic arthritis.
