MIT engineers have boosted stem cells’ ability to regenerate vascular tissue (such as blood vessels) by equipping them with genes that produce extra growth factors (naturally occurring compounds that stimulate tissue growth). In a study in mice, the researchers found that the stem cells successfully generated blood vessels near the site of an injury, allowing damaged tissue to survive.
Why it matters: Stem cells hold great potential as a way to promote tissue regeneration. However, this approach has been limited because stem cells don’t produce enough growth factors after transplantation. The researchers’ new super-charged stem cells could be used to

In the near future, hearts that have just suffered a heart attack will be able to repair themselves, according to an incredible discovery of how to reeducate cardiac stem cells to repair damaged hearts. In fact, stem cells normally perform the delicate task of repairing cardiac muscle, but after a heart attack the cells no longer carry out this highly important self-repair.
Italian scholars at the ‘Sapienza’ University in Rome and the European Molecular Biology Laboratory (EMBL) in Monterotondo, have discovered why these cells stop functioning correctly, and now understand how to induce them to
Doctors may soon be able to ‘draw’ new bone, skin and muscle on to patients, after scientists created a pen-like device that can apply human cells directly on to seriously injured people.
The device contains stem cells and growth factors and will give surgeons greater control over where the materials are deposited.
It will also reduce the time the patient is in surgery by delivering live cells and growth factors directly to the site of injury, accelerating the regeneration of functional bone and cartilage, scientists said.

A research group at Imperial College London has designed a new treatment able to significantly improve the body’s capacity to repair damage caused by a heart attack or bone fracture. The new therapy, described in Cell Stem Cell, ‘fools’ the spinal cord inducing it to ’overproduce’ stem cells which repair damaged tissues in the body. Researchers hope to test the treatment on animals by the end of the year. If testing is successful, the next step will be to experiment on human beings attempting to induce them to use their own stem cells
An international team of physicians and scientists in Florida have discovered a way to treat cardiomyopathy (heart disease) with adult stem cells, including a rare metabolic condition otherwise requiring heart transplant.
Regenocyte Therapeutic is using stem cells extracted from patients’ blood to repair damaged heart muscle, regenerate tissue, and create new vessels to improve circulation. According to the organization’s director of Cardiology and Vascular Disease, Zannos G. Grekos, M.D., by applying specific growth factors to the patient’s stem cells the team creates a new cell population which is educated to target the area of damage or deficiency when placed into
