Johns Hopkins University biologists have found that a protein that plays a key role in the lives of stem cells can bolster the growth of damaged muscle tissue, a step that could potentially contribute to treatments for muscle degeneration caused by old age and diseases such as muscular dystrophy.

A Johns Hopkins University biologist has led a research team reporting progress in understanding the mysterious shape-shifting ways of stem cells, which have vast potential for medical research and disease treatment.
A Johns Hopkins engineering professor who is coaxing stem cells into forming blood vessels that can nurture healthy tissue or starve cancer cells is the first recipient of a new university award that provides $250,000 in research funding. The inaugural President’s Frontier Award was announced Jan. 28 during a surprise presentation at recipient Sharon Gerecht’s lab on the university’s Homewood Campus in Baltimore. Gerecht is an associate professor in the Whiting School of Engineering’s Department of Chemical and Biomolecular Engineering.
Growing new blood vessels in the lab is a tough challenge, but a Johns Hopkins engineering team has solved a major stumbling block: how to prod stem cells to become two different types of tissue that are needed to build tiny networks of veins and arteries. The team’s solution is detailed in an article appearing in the journal Cardiovascular Research. The work is important because networks of new blood vessels, assembled in the lab for transplanting into patients, could be a boon to people whose circulatory systems have been damaged by heart disease, diabetes and other illnesses.
Johns Hopkins researchers have discovered that a single protein molecule may hold the key to turning cardiac stem cells into blood vessels or muscle tissue, a finding that may lead to better ways to treat heart attack patients.
Johns Hopkins graduate students have invented a system to significantly boost the number of stem cells collected from a newborn’s umbilical cord and placenta, so that many more patients with leukemia, lymphoma and other blood disorders can be treated with these valuable cells.
