New advancements in the use of adult, embryonic stem cells for tissue regeneration
...s all species. It functions throughout the life cycle to maintain or restore the normal form and function of cells, tissues and, in some cases organs, appendages and whole organisms. The roots, stems and leaves of plants, for example, have extensive regenerative capacity, and entire plants can grow from single ...How Candida albicans transforms from its normally benign form into life-threatening form
...us phase of C. albicans. The fungus starts its 'attack' on a patient by changing its oval shape into a filamentous form, which has thin, threadlike appendages emerging from the cell body. Wang's team, who has been studying C. albicans for more than seven years, was responsible for identifying the master "con...Regrowth of Zebrafish's Tail Fin may Offer Clues for Treating Human Injuries
... is a very intricate structure. It is the fish version of an arm or leg. The question of how cold-blooded animals re-grow missing tails and other appendages has fascinated veterinary and medical scientists. They also wonder if people, and other warm-blooded animals that evolved from these simpler creatures...Navigating in the ocean of molecules

... A University of Florida scientist whose interest in embryonic development and evolution led him to discover the molecular building blocks that shape appendages ranging from feet to flippers was named a Howard Hughes Medical Institute Early Career Scientist today (Thursday, March 26), a distinction given to on...Research links evolution of fins and limbs with that of gills
...rchers, the genetic circuitry that patterns paired appendages (arms, legs and fins) has a deep evolutionary origin that actually predates the origin of paired appendages themselves. "These findings suggest that when paired appendages appeared, the mechanism used to pattern the skelet...Origin of claws seen in 390-million-year-old fossil

...a gene called ephrin-A from the retina." Unlike p75, ephrin-A was a well-characterized sender and receiver of axon guidance signals, but it lacked appendages normally seen on proteins controlling axon migration. p75, however, displayed those elements, suggesting that the proteins could pair up one receivin...UT Southwestern researchers create molecule that nudges nerve stem cells to mature
... study, rodent nerve stem cells from an area of the brain called the hippocampus were cultured with Isx-9. They clustered together and developed spiky appendages called neurites, which typically happens when nerve cells are grown in culture. Isx-9 also prevented the stem cells from developing into non-nerve...Scientists discover 'dancing' algae
...roximately 1,000 cells arranged on the surface of a spherical matrix about half a millimetre in diameter. Each of the surface cells has two hair-like appendages known as flagella, whose beating propels the colony through the fluid and simultaneously makes them spin about an axis. The researchers found that c...
