Significant racial discordance between nurses and patients in Black-serving hospitals

Significant racial discordance between nurses and patients in Black-serving hospitals

A new Penn Nursing Center for Health Outcomes and Policy Research study reveals a significant underrepresentation of Black nurses compared to the Black patient populations they serve, particularly in hospitals that care for a higher proportion of Black patients. The study, led Eileen T. Lake, the Edith Clemmer Steinbright Professor in Gerontology, Professor of Nursing and Sociology, and CHOPR associate cirector, is set to be published in Nursing Research.

Key to improving survival of transplanted retinal cells
Microscopic view of transplanted human cells.

Photomicrograph shows a small number of transplanted human cells (in red) that survived the stress of transplantation and were able to integrate and differentiate into cone photoreceptors in a partially degenerated canine retina.

New device could streamline vision-saving therapies

New device could streamline vision-saving therapies

A new study by a team of vision scientists from the Division of Experimental Retinal Therapies at Penn Vet, led by William A. Beltran, have worked to demonstrate that a novel surgical tool used previously in gene and cell therapy clinical trials can place therapies directly beneath the retina using a minimally invasive approach.

Stem cell secretions show promise in boosting oral tissue regeneration

Stem cell secretions show promise in boosting oral tissue regeneration

A preclinical study from researchers at Penn Dental Medicine shows that the molecular secretions of stem cells taken from human gum tissue could someday be used to speed the healing and regeneration of damaged tissues in the mouth.
