Obesity Study Looks At Brown Fat Cells
2013-03-15 06:11:35

Enid Burns for redOrbit.com — Your Universe Online Many of us don't know the difference between brown fat cells and white fat cells. But researchers at Perelman School of Medicine at the University of Pennsylvania, led by Patrick Seale, Ph.D., are looking at brown fat cells to better understand how they develop. The researchers believe that the brown fat cell makes heat for the body, which has helped mammals cope with the cold. New theories say the warmth generated in brown fat...

Scientists Grow Teeth From Gum Cells

Lee Rannals for redOrbit.com — Your Universe Online A new technique developed by an expert in craniofacial development and stem cell biology at King's College London and his colleagues offers up a new type of tooth replacement. The scientists wrote in the Journal of Dental Research about how they developed a new method of replacing missing teeth with a bioengineered material enervated from a person's own gum cells. Current methods for replacing teeth fail to reproduce a...

Researchers at the Stanford University School of Medicine have identified a group of progenitor cells in the inner ear that can become the sensory hair cells and adjacent supporting cells that enable hearing. Studying these progenitor cells could someday lead to discoveries that help millions of Americans suffering from hearing loss due to damaged or impaired sensory hair cells. "It's well known that, in mammals, these specialized sensory cells don't regenerate after damage," said Alan...

Stem Cells In A Human Parasite Revealed Through Study
2013-02-26 09:31:26

University of Illinois From the point of view of its ultimate (human) host, the parasitic flatworm Schistosoma mansoni has a gruesome way of life. It hatches in feces-tainted water, grows into a larva in the body of a snail and then burrows through human skin to take up residence in the veins. Once there, it grows into an adult, mates and, if it´s female, starts laying eggs. It can remain in the body for decades. A new study offers insight into the cellular operations that give...

The Future of Regenerative Medicine: Dental Pulp Stem Cells and Dental Pulp Stem Cell Banking MIAMI, Florida (PRWEB) February 25, 2013 GeneCell International, a trusted provider in the processing and preservation of umbilical cord blood, today announced industry changing technologies in Honduras, via its affiliate, Drogueria Americana, that allow for the collection and storage of Dental Pulp Stem Cells, a type of multi-potent adult stem cell found in the pulp chamber of teeth, which show a...

Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells. When this regulation is disrupted, white fat cells are unable to accumulate lipid droplets or mature from their precursors. "We're trying to figure out what the mechanism is–what it takes to make fat cells," says Whitehead Founding Member Harvey Lodish, who is also a professor of biology and a professor of...

Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered that a protein called Jagged-1 stimulates human stem cells to differentiate into bone-producing cells. This protein could help both human and animal patients heal from bone fractures faster and may form the basis of treatments for a rare metabolic condition called Alagille syndrome. The study, published in the journal Stem Cells, was authored by three members of Penn Vet´s departments of...

A single embryonic stem cell can develop into more than 200 specialized cell types that make up our body. This maturation process is called differentiation and is tightly regulated through strict control of gene activity. If the regulation is lost, specialized cells cannot develop correctly during development. In adulthood, the specialized cells may forget their identity and develop into cancer cells. Research from BRIC, University of Copenhagen, has identified a crucial role of the molecule...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
