Creeping crinoids! Sea lilies crawl to escape predators, new video shows

...hers found that some sea lilies regularly shed and regenerate the ends of their stalks. Interestingly, the stalks don't break off just anywhere, but at particular nodes, just below clusters of flexible, finger-like appendages. Baumiller and Messing speculated that the sea lilies might be shedding the ends of th...

MIT researcher finds neuron growth in adult brain

... While scientists have focused mostly on trying to regenerate the long axons damaged in spinal cord injuries, the new finding suggests targeting a different part of the cell: the dendrite. A dendrite, from the Greek word for tree, is a branched projection of a nerve cell that conducts electrical stimulation to ...

New understanding of regeneration gained by Forsyth scientists

...e worm's cells communicate to correctly repair and regenerate tissue. Forsyth scientists have found that gap-junction (microscopic tunnels directly linking neighboring cells) communication contributes to this signaling. This research, led by Dr. Michael Levin, underlies principles that can potentially offer in...

New study identifies key gene in development of connections between brain and spinal cord

...duction could be essential in understanding how to regenerate connections to the spinal cord that are severed during injury, which results in paralysis. "The discovery of Fezl is a critical finding in unlocking the intricacies of human brain development," noted McConnell. "However, there is still much resea...

Liver cancer linked to cellular repair pathway

... study. The liver's attempts to repair itself and regenerate new tissue after injury can trigger the Hedgehog pathway. During embryonic development, Hedgehog tells cells where and when to grow. In adult tissue, it signals the body to grow new tissue. "If the liver is injured badly, it uses some of the same mec...

New research demonstrates bone-marrow derived stem cells can reverse genetic kidney disease

... discovery that bone-marrow derived stem cells can regenerate damaged renal cells in an animal model of Alport syndrome provides a potential new strategy for managing this inherited kidney disease and offers the first example of how stem cells may be useful in repairing basement membrane matrix defects and rest...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...ogists are hoping that transplanted stem cells can regenerate damaged heart muscle in those who experience a first heart attack. The study involves an intravenous infusion of adult mesenchymal stem cells from healthy donor bone marrow that might possibly reverse damage to heart tissue. A unique benefit of the ...
