A new, low-cost wound dressing developed by University of Wisconsin-Madison engineers could dramatically speed up healing in a surprising way.
Researchers at the Mainz University Medical Center discovered a new signal pathway employed by skin cancer cells to avoid attack by the immune system. In an animal model and through analysis of human tissue samples, Dr. Toszka Bohn, Dr. Steffen Rapp and Professor Tobias Bopp were able to demonstrate the significant role played by a specific protein called ICER.
By stirring crosstalk among skin cells that form the roots of hair, researchers report they have regrown hair strands on damaged skin. The findings better explain why hair does not normally grow on wounded skin, and may help in the search for better drugs to restore hair growth, say the study's authors.
Researchers at the University of New Hampshire have created an easy-to-make, low-cost injectable hydrogel that could help wounds heal faster, especially for patients with compromised health issues.
Diabetic foot ulcers can take up to 150 days to heal. A biomedical engineering team wants to reduce it to 21 days.
Fresh insights into how zebrafish repair their damaged nerve connections could aid the development of therapies for people with spinal cord injuries.
An enzyme known to help our liver get rid of ammonia also appears to be good at protecting our retina, scientists report.
The CRISPR genome editing technique promises to be a "transformative leap" in genetic engineering and therapy, affecting almost every area of medicine.
