Do stem cells really hold the key to understanding and curing many diseases? What's the connection between embryonic development and tissue regeneration? Doug Melton and Nadia Rosenthal are leaders in stem cell research, working primarily with mouse and human tissue. They will discuss where embryonic and adult stem cells come from and the biology of how they supply the cells the body needs. Stem cells are fundamental to biology. In the course of embryonic development, stem cells generate all the specialized cells that populate body tissues like muscle, the nervous system, and blood. In adults, reserves of stem cells repair and regenerate tissues damaged by disease and wounding. Because of the potential of stem cells to generate fresh, healthy cells, there is a huge interest in cultivating them to treat various diseases. This year's Holiday Lectures will explore exciting progress toward the goal of harnessing stem cells to treat diabetes, nerve damage, and heart disease.

Portrait of When Nadia Rosenthal donned the scientist’s white lab coat she became the black sheep of the family. Rosenthal’s father is an Emmy Award-winning composer; her mother was a concert pianist. Her sister became a potter. Rosenthal herself is a serious painter. But while growing up in New York City, Rosenthal was inspired by a high school teacher to choose a life in science. Read more... Stemming Disease What is the best way to get from the Midwest to Harvard University? For Douglas Melton, the optimal route to Cambridge, Massachusetts, passed through Cambridge University in England. Stops that he made there prepared him in a unique way for the subject matter that became his research focus: stem cells. Read more...
