Scientists have taken the first steps toward producing the “heart patch,” a design for a medical implement used to repair damage from heart disease, a new study suggests.
Last week, researchers from Duke University presented the results of a study which, using mouse embryonic stem cells, examined the way these cells develop into heart muscle, HealthDay News reports (…)
Viet Nam’s National Hospital of Pediatrics in Ha Noi this morning announced the initial success of its first stem cell therapy treatment of epidermolysis bullosa (EB), making it only the second medical institution in the world to successfully treat this genetic skin disease in this manner.
Children with EB lack a protein that anchors the outer layer of skin to the body, resulting in very fragile skin that peels off with minor friction or trauma. They suffer painful wounds and infections which eventually are fatal.

A procedure using stem cells may provide a more thorough regeneration of periodontal tissue around dental implants, according to a new report published in the Journal of Oral Implantology.
Dental implants closely resemble natural teeth, but an implant’s ability to react to patient growth, pressure from chewing, and future orthodontic work is diminished if it is not surrounded by sufficient periodontal tissue.
In this study, the authors engineered this periodontal tissue in a fresh socket of a goat animal model. Each of five goats was fitted with two titanium implants immediately after tooth removal. A poly DL-Lactide-co-Glycolide scaffold was
The first operations have been successfully performed at Seriate Hospital (Bergamo) using autologous stem cell transplants to rebuild a part of the breast after removing a tumor. The technique used in the operation is known as ‘lipofilling’, which calls for some of the patient’s abdominal fat to be removed in a procedure similar to liposuction. The fat is then purified and manipulated in the laboratory to concentrate stem cells as much as possible, then they are transplanted into the portion of the breast that has been removed to eliminate the cancer.
It has long been thought that damage to the heart is irreversible, but new research is challenging that assumption.
Investigators from Children’s Hospital Boston were able to reverse heart damage in mice by stimulating the growth of new heart muscle cells.
They did this by injecting the mice with the growth factor neuregulin1, which is a key player in heart cell growth.
Until recently, most experts believed that the heart muscle could not repair itself, in part because the cells responsible for its development stop proliferating after birth.
But recent studies have shown that these heart muscle cells, known as cardiomyocytes, do have
