FINDINGS: Devising a novel method to identify potential genetic regulators in planarian stem cells, Whitehead Institute scientists have determined which of those genes affect the two main functions of stem cells. Three of the genes are particularly intriguing because they code for proteins similar to those known to regulate mammalian embryonic stem cells. Such genetic similarity makes planarians an even more attractive model for studying stem cell biology in vivo. RELEVANCE: Stem cells may...

Researchers at the University of California, San Francisco and the Stowers Institute for Medical Research have discovered that planarians, tiny flatworms fabled for their regenerative powers, completely lack centrosomes, cellular structures that organize the network of microtubules that pulls chromosomes apart during cell division. The flatworms' unique and unexpected characteristic, detailed in the Jan. 5, 2012 issue of Science Express, not only allowed lead author Juliette Azimzadeh,...

(Ivanhoe Newswire) — Damaged heart tissue typically doesn´t repair itself, but scientists may have identified signals that are able to coax the heart into producing replacement cardiac muscle cells. Using a zebrafish model system, researchers have identified a family of molecules that can stimulate stem cells to develop into beating heart muscle cells. "Despite advances in modern medicine, management of myocardial infarction and heart failure remains a major challenge," senior...

Damaged heart tissue is not known for having much inherent capacity for repair. But now, scientists are closing in on signals that may be able to coax the heart into producing replacement cardiac muscle cells. Using a zebrafish model system, researchers have identified a family of molecules that can stimulate stem cells to develop into beating heart muscle cells. The research, published by Cell Press in the December 21st issue of the journal Chemistry & Biology, may pave the way towards...

UK scientists create a functional model of the extracellular matrix which could lead to advances in regenerative medicine Scientists at the National Physical Laboratory (NPL) have created a functional model of the native extracellular matrix that provides structural support to cells to aid growth and proliferation. The model could lead to advances in regenerative medicine. The extracellular matrix (ECM) provides the physical and chemical conditions that enable the development of all...

Researchers Study Hellbender Salamanders For Answers For Global Amphibian Decline
2011-12-20 10:43:34

A new study co-authored by University of Florida researchers on the endangered Ozark Hellbender giant salamander is the first to detail its skin microbes, the bacteria and fungi that defend against pathogens. Published today in the online journal PLoS One, the study details changes in the salamander's declining health and habitat, and could provide a baseline for how changing ecosystems are affecting the rapid decline of amphibians worldwide. "Scientists and biologists view amphibians...

Hydrogel Helps Grow New, Scar-free Skin For 3rd Degree Burn Patients
2011-12-14 05:33:03

Johns Hopkins researchers have developed a jelly-like material and wound treatment method that, in early experiments on skin damaged by severe burns, appeared to regenerate healthy, scar-free tissue. In the Dec. 12-16 online Early Edition of Proceedings of the National Academy of Sciences, the researchers reported their promising results from mouse tissue tests. The new treatment has not yet been tested on human patients. But the researchers say the procedure, which promotes the formation...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
