Dyskeratosis congenita, or DC, is a rare, inherited disease for which there are limited treatment options and no cure. Typically diagnosed in childhood, the disorder causes stem cells to fail, leading to significant problems including bone marrow failure, lung fibrosis, dyskeratosis of the skin and intestinal atrophy and inflammation.

Cancerous tumors must be fed. Their unregulated growth requires a steady stream of blood flow and nutrients. Thus, one way that researchers have tried to wipe out cancer is to target cells undergoing the metabolic shifts that enable a tumor’s rapid growth.

Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, ageing and disease.  In tissues that turn over rapidly, such as the intestines, the self-renewing nature of stem cells and their susceptibility to cancer-causing mutations has led researchers to postulate that

Patients who are critically ill, be they dog, cat or human, have a tendency toward blood clotting disorders. When the formation of a clot takes too long, it puts them at risk of uncontrolled bleeding. But the other extreme is also dangerous; if blood clots too readily and a clot travels to the lungs, brain or heart, it can lead to organ failure or even death.

A doctoral student at the University of Pennsylvania has identified a new species of fossil dog. The specimen, found in Maryland, would have roamed the coast of eastern North America approximately 12 million years ago, at a time when massive sharks like megalodon swam in the oceans.

The human placenta is an organ unlike any other. During the course of nine months it is formed by the embryo, sustains life and then is shed.

Three graduate students from the University of Pennsylvania have been selected as Medical Research Fellows by the Howard Hughes Medical Institute.
