Engineered Developmental Signals Could Illuminate Regenerative Medicine

Scientists are still working to understand how morphogens’ signals are broadcast over just the right distances and how cells are calibrated to respond to the proper concentration at the appropriate time. But these questions are difficult to investigate because natural morphogens interact with their environment in many complexes, hard to define ways. Instead of deconstructing […]

Big Step in Regenerative Medicine

Harvard Medical School surgeons at Massachusetts Eye and Ear have replaced the ocular surface of four patients who each experienced chemical burns to one eye. The technique, cultivated autologous limbal epithelial cell transplantation (CALEC), uses stem cells taken from a patient’s healthy eye. These four cases are part of an ongoing clinical trial supported by […]
