Mesenchymal stem cells may eventually be able to grow and strengthen muscles in humans, according to researchers at the University of Illinois. In mice, an injection of such stem cells helped rejuvenate skeletal muscle after exercise.
Researchers have figured out a way to identify stem cells in tissue from deceased human donors and use them to regrow anatomically correct, fully functional human corneas in mice.
Scientists at the University of Missouri have successfully transplanted and grown stem cells in pigs, pointing the way to a similar method that could eventually be used in people.
Despite the promise that stem cell technology has shown for regenerative medicine, heart attack patients who receive an injection of stem cells to regenerate damaged heart tissue may not actually benefit from the therapy.
By injecting mice with a signaling protein, researchers from the Harvard Stem Cell Institute were able to repair failing hearts and improve brain and skeletal muscle function in aging mice so that the animals resembled young, healthy mice.
Scientists report that they have replicated a method of growing stem cells from adults using cloning techniques--a discovery that could help propel patient-specific regenerative therapies for a myriad of medical conditions and diseases.
A softer, plusher environment made of a key ingredient in Silly Putty may allow embryonic stem cells to grow faster and produce more specialized cells than traditional methods of making stem cells.
In another step toward using stem cells for regenerative medicine, investigators from the University of Wisconsin-Madison have discovered a new way to make skeletal muscle cells and muscle progenitors in bulk from human pluripotent stem cells.
Researchers have found a way to transform skin cells into fully functioning mature liver cells that grow on their own after being transplanted into mice.
An experimental gene therapy developed by investigators at the Icahn School of Medicine at Mount Sinai successfully regenerated heart muscle in pigs following a heart attack.
