When smell cells fail they call in stem cell reserves

...ive type of nasal stem cell.? The team then went back and looked at nerve repair under less damaging circumstances where only the olfactory nerve cells are killed. In this situation, the HBCs did nothing to repair the damaged cells; rather, they allowed the previously known stem cells to do all the repa...

Biologists call for better choice of model organisms in 'evo-devo'

...pmental biology, known as ‘evo-devo? is being held back because the dominant model organisms used by scientists are unable to illustrate key questions about evolution, argue biologists in the latest issue of Nature Reviews Genetics. The subject of evo-devo, which became established almost a decade ago, i...

Research project tackles 'regeneration' gap

...opment. We want to learn how to turn those systems back on in people." Recently, studies have shown humans possess some of the same genes and communication pathways used by some of nature’s most remarkably regenerative animals. Already, UF McKnight Brain Institute scientists have discovered more th...

Researchers show that veins stiffen as we age

...s to the veins. The veins then transport the blood back to the heart. The veins are equipped with valves to prevent any backflow of blood caused by gravity as blood is returned to the heart from the lower extremities. The walls of the veins are made of collagen and elastin, two proteins that give the tu...

"This study gets at some of the important mechanistic questions about how they rebuild the heart, and some of the key factors that contribute." In contrast to zebrafish, the cardi...

Because this study looked back at patients treated years ago, the researchers could look for differences between patients who subsequently suffered chronic lung rejection and those who did not.

The team traced that protein density back to a portion of the polymerase II enzyme: the trigger loop. “Of the 14 crystal structures now reported in which the trigger loop was observed, only in two is it seen in that location, directly beneath the NTP,?Kornberg said. Those were the only two...
