Sticky gel helps stem cells heal rat hearts

September 28, 2015 by · Leave a Comment 

A sticky, protein-rich gel created by Johns Hopkins researchers appears to help stem cells stay on or in rat hearts and restore their metabolism after transplantation, improving cardiac function after simulated heart attacks, according to results of a new study.

Johns Hopkins researchers engineer custom blood cells

March 9, 2015 by · Leave a Comment 

Researchers at Johns Hopkins have successfully corrected a genetic error in stem cells from patients with sickle cell disease, and then used those cells to grow mature red blood cells, they report. The study represents an important step toward more effectively treating certain patients with sickle cell disease who need frequent blood transfusions and currently have few options.

Researchers use human stem cells to create light-sensitive retina in a dish

June 22, 2014 by · Leave a Comment 

Using a type of human stem cell, Johns Hopkins researchers say they have created a three-dimensional complement of human retinal tissue in the laboratory, which notably includes functioning photoreceptor cells capable of responding to light, the first step in the process of converting it into visual images.

stem cells derived from human body fat uman fat: A trojan horse to fight brain cancer?

May 1, 2014 by · Leave a Comment 

Johns Hopkins researchers say they have successfully used stem cells derived from human body fat to deliver biological treatments directly to the brains of mice with the most common and aggressive form of brain tumor, significantly extending their lives.

Lost stem cells naturally replaced by non-stem cells, fly research suggests

April 18, 2014 by · Leave a Comment 

Johns Hopkins researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies: When a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them.

Stem cells may do best with a little help from “helper cells”

August 28, 2013 by · Leave a Comment 

Like volunteers handing out cups of energy drinks to marathon runners, specially engineered “helper cells” transplanted along with stem cells can dole out growth factors to increase the stem cells’ endurance, at least briefly, Johns Hopkins researchers report. Their study, published in the September issue of Experimental Neurology, is believed to be the first to test the helper-cell tactic, which they hope will someday help to overcome a major barrier to successful stem cell transplants.

Johns Hopkins researchers return blood cells to stem cell state

August 22, 2012 by · Leave a Comment 

Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

Adult stem cells take root in livers and repair damage

May 11, 2011 by · Leave a Comment 

Johns Hopkins researchers have demonstrated that human liver cells derived from adult cells coaxed into an embryonic state can engraft and begin regenerating liver tissue in mice with chronic liver damage.
