...eye is such a unique place, you've got this bag of jelly -- the vitreous -- that just sits there and it fills up with SDF-1. The SDF-1 doesn't break down. It continues to call the new blood vessels to come that way, causing all the problems."

...hymal stem cells," says Davies. "We found that the jelly tissue immediately around the vessels had the richest population of these cells. Once we isolate them, it only takes 21 days to generate enough stem cells for up to 1000 therapeutic cell doses." Bone marrow transplants treat diseases such as cancer...Deep-sea jelly uses glowing red lures to catch fish
...re scientists recently discovered a new species of jelly that attracts fish by wiggling hundreds of glowing... to catch animals that happen to swim by. But this jelly doesn't deploy its tentacles very far. In an environment where fish are rare, it uses deception to a...Scientists discover the molecular switch for nerve cells' insulating jelly rolls
...f myelin, producing the biological equivalent of a jelly roll. Using a sophisticated system for growing nerve cells in laboratory dishes, the team identified a gene called neuregulin as the myelin signal. This signal directs Schwann cells, the nervous system's cellular architects, to build elaborate sheath...Engineering nerve jumper cables for spinal cord repair in animal model
...h growth factors), rolled into a form resembling a jelly roll, and then implanted into a rat model of spinal cord injury. "That creates what we call a nervous-tissue construct," says Smith. "We have designed a geometrical arrangement that looks similar to the longitudinal arrangement that the spinal cord ...A new look at the state of the oceans
...-floating organisms in the water, from bacteria to jelly fish. The image material and related information on planktonic organisms, e.g. taxonomic descriptions, facilitate the identification of species. The data base was re-installed recently and, at present, holds more than 3000 images and over 500 species...Researchers devise new tools to help pinpoint treatments for heart failure
...use of an engineered protein partly derived from a jelly fish that fluoresces within heart cells in tandem with activation of the key enzyme called PKA (protein kinase A). By combining computer modeling with the novel fluorescence-imaging technique in living cells, the researchers were able to uncover new ...Boston University biologists discover amphibian eggs use defenses against water molds

Extensive analyses will be conducted to prove whether or not ...... workers synthesize vitellogenin to make the royal jelly they feed larvae. It can also prolong the lifespan of both workers and the queen by reducing oxidative stress.
