Protein-coated dental implants could improve bone regeneration

... "For the past 20 years, there has been a quest to regenerate tissues around teeth that are lost due to periodontal disease," he says. "I've looked at multiple approaches to achieve regeneration, including bone grafts, root conditioning and membrane devices for directed tissue growth, all resulting in some rege...

Scientists identify gene involved in stem cell self-renewal in planaria

...eshwater planarian possesses an amazing ability to regenerate lost body parts. Chop one into pieces, and each piece can grow into a complete planarian. The flatworm relies upon a population of stem cells to accomplish this remarkable feat; recent work sheds light on how planarians maintain these stem cells thro...

Fat stem cells being studied as option for breast reconstruction

...nter. The use of stem cells to treat disease or regenerate tissue is believed to hold promise because of their potential to develop into different specialized cell types. Indeed, when exposed to specific conditions in the laboratory, fat-derived stem cells have been shown to differentiate into cells characte...

Fragmentation rapidly erodes Amazonian biodiversity

...t and knock down a lot of trees.? The trees that regenerate in their place are very different from the trees that died. “When you fragment a forest, the winners are common pioneer and generalist species that like forest disturbance,?said Laurance. “The losers are rare, slow-growing tree species that provide...

Cancer stem cells linked to radiation resistance

...s cells, a small fraction of them remain and often regenerate into even larger masses of tumor cells. Until recently, scientists knew little about what made these resistant cells different from those that succumb to radiation treatment. It was clear, however, that the cells shared characteristics similar to ...

Getting to the heart of the heart

...o bring researchers a step closer to being able to regenerate tissues to repair congenital heart defects in children and damage caused by heart attacks in adults. The two laboratories are now trying to determine the relationship between the two types of progenitor cells discovered. Both papers will appear i...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...how from diverse disciplines to repair, replace or regenerate cells, tissues or organs impaired by congenital defects, disease, trauma and other causes. It moves beyond traditional transplant and replacement therapies to include the use of stem cells, soluble molecules, genetic engineering, tissue engineering,...

From managing sugar to managing healing

...f topical insulin on keratinocytes, the cells that regenerate the epidermis after wounding, and on microvascular endothelial cells, the cells that restore blood flow. Using various cell and molecular techniques, the researchers discovered that insulin stimulates human keratinocytes in culture to proliferate ...

Inheritance outside DNA

... behavior of the adult stem cells that continually regenerate the colon in mice. This probably plays a role in the increased risk of colon cancer, says Feinberg. Spotting epigenetic markers like lost IGF2 in humans could be used in future cancer-prevention strategies. Says Feinberg, “It could be possible to ...

First Quantum Grant to fund stem cell repair of damage from stroke
