An injectable hydrogel could aid recovery from brain injury by helping stimulate tissue growth at the site of the wound, researchers say.
Research on rats suggests the gel, made from synthetic and natural sources, may spur growth of stem cells in the brain (…)
Researchers say the advantage of the new gel, which is injected into the injury in liquid form, is that it can be loaded with different chemicals to stimulate various biological processes.

A biodegradable tissue to repair hearts after a heart attacks or to cure congenital malformations. A tissue that acts like a porous, accordion-like medium onto which cardiac stem cells are ‘implanted’ has been created by scientists from the prestigious Massachusetts Institute of Technology in Boston (MIT). This “bioscaffolding” integrates perfectly with cardiac tissue and creates a biological “band-aid” that is slowly reabsorbed and repairs cardiac muscle.
Compared to similar previous attempts, explained George Engelmayr in “Nature Materials” magazine, the advantage of the “bioscaffolding” is that it faithfully mirrors cardiac tissue structurally and mechanically, and
Cincinnati Children’s Hospital Medical Center, known for “miracle” surgeries, has completed a medically historic procedure where doctors used stem cells taken from the fat tissue of a 14-year-old boy and combined them with growth protein and donor tissue to grow viable cheek bones in the teen.
Brad Guilkey, 15, suffers from a rare kind of genetic disorder known as Treacher Collins Syndrome, where the bones and other tissues are prevented to develop in the face (…)
The medical team implanted cadaver bone into Brad’s face in May, and then they injected his own stem cells into the donor bone to fill
All those who have suffered ligament damage could benefit from artificial ligaments built biologically. But, experimentation on artificial ligaments, which could come from stem cells and naturally replace damaged tissue, will not continue. Speaking about the issue was Luigi Ambrosio, one of the researchers of the Institute of Technology of Composite Material of the National Research Council (CNR) in Naples, who contributed to the realization of this biological ligament. Two solutions were proposed by the Neapolitan laboratory.
One solution was to build a biodegradable structure out of hyaluronic acid, one of the components of ligament
