(Harvard Medical School) Researchers have developed a simple method for making a certain class of adult stem cells more therapeutically effective. By attaching a molecule called SLeX to the surface of human cells extracted from bone marrow, researchers have altered how the cells travel through vessels. This might enable the cells to more effectively reach sites of injury and replace damaged tissue.

In a promising finding for the field of regenerative medicine, stem cell researchers have identified a source of adult stem cells found on the walls of blood vessels with the unlimited potential to differentiate into human tissues such as bone, cartilage and muscle.

Adult Stem Cells Activated In Mammalian Brain

Adult stem cells originate in a different part of the brain than is commonly believed, and with proper stimulation they can produce new brain cells to replace those lost to disease or injury, a new study has shown.

In an approach that could become a new treatment for the 10 to 20 percent of people whose broken bones fail to heal, researchers have shown that transplantation of adult stem cells can improve healing of fractures.

(University of California - Berkeley) When UC Berkeley bioengineers tweaked how adult stem cells reacted to biochemical signals regulating cell division, they gave muscle in old mice a shot of youthful vigor. The research sets the path for research on new treatments for age-related degenerative conditions, including muscle atrophy and Alzheimer's disease.

Bone Repair Using Patient's Stem Cells Comes Closer

Enzyme induces adult stem cells to grow bone. Until now it has been difficult to induce adult human stem cells to produce bone, e.g. in order to repair bone tissue. Researchers have just shown that if the enzyme PKA is previously activated in the stem cells in the lab, following implantation this results in substantial bone formation. This opens up new ways of repairing bone tissue using cell material from the patient.

Stem Cells Found For The First Time In The Pituitary

Scientists have for the first time identified stem cells that allow the pituitary glands of mice to grow even after birth. They found that, in contrast to most adult stem cells, these cells are distinct from those that fuel the initial growth of this important organ. The results suggest a novel way that the hormone-secreting gland may adapt, even in adolescents and adults, to traumatic stress or to normal life changes like pregnancy.

Researchers have made an important step towards the use of adult stem cells to repair damaged tissue. University of Manchester scientists report that they have uncovered a messaging system that instructs adult stem cells to contribute to tissue repair in response to chemical signals in the body.

Researchers in the United Kingdom are investigating a mechanism that normally drives adult stem cells to repair the intestine. They have found that if things go wrong and a crucial gene called Apc is lost or damaged, then this normal function of controlling the adult stem cell population breaks down and ultimately leads to a tumour.

Power of molecular imaging reveals secrets of the heart

The extraordinary action of a new cellular therapy came to light as a result of powerful PET and SPECT imaging in a recent study reported in the April issue of the Journal of Nuclear Medicine. Researchers in Germany were able to observe the repair action of circulating progenitor cells, immature blood-derived cells capable of developing into adult stem cells, as they successfully preserved healthy heart tissue and corrected blood flow imbalance within the heart.
