Fat stem cells being studied as option for breast reconstruction
...enter. 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...Earliest fungi may have found multiple solutions to propagation on land, new study infers
...ushroom varieties that "shoot out" spores that can regenerate wherever they land, said study co-author Rytas Vilgalys, a Duke biology professor who specializes in fungi and who supervised James' postdoctoral research. According to Vilgalys, what makes a fungus a fungus is not the way it propagates but how it ...Fatty acids and caveolin-1 are essential in liver regeneration

Summarising, this work makes two important contributions: On the one hand, it reveals the main vital function of lipid bodies and caveolin. This is a protein linked to the storage of lipids and cell cycle, but a situation...A plastic pill for periodontal problems

...sponsible for causing key brain cells, neurons, to regenerate and ultimately restore brain function. The research study focused on two compounds--LTB4 and LXA4.

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...Mapping system tells skin cells whether to become scalp, palm tissues, Stanford study finds
...with function in a way that will make it easier to regenerate certain parts of the body," said Rinn. "For example, if we need to grow skin in the laboratory to graft onto someone with badly burned palms, we'll know how to turn on the specific genes that make that type of skin."
