Neural Crest Hypothesis Could Explain Why Domestic Mammals Share Characteristic Traits
2014-07-14 03:02:44

Genetics Society of America More than 140 years ago, Charles Darwin noticed something peculiar about domesticated mammals. Compared to their wild ancestors, domestic species are more tame, and they also tend to display a suite of other characteristic features, including floppier ears, patches of white fur, and more juvenile faces with smaller jaws. Since Darwin's observations, the explanation for this pattern has proved elusive, but now, in a Perspectives article published in the journal...

gum tissue stem cells heal inflammation

April Flowers for redOrbit.com - Your Universe Online A new study from the Ostrow School of Dentistry of the University of Southern California (USC) reveals stem cells found in mouth tissue can relieve inflammatory disease, as well as become other types of cells. The study, published in a recent issue of the Journal of Dental Research, focused on gingival mesenchymal stem cells (GMSC) that are found in the gingival, or gum tissue, of the mouth. Like other stem cells, GMSC have the...

Origins Of Our Smell Cells Pinpointed By Scientists

redOrbit Staff & Wire Reports - Your Universe Online Biologists at the California Institute of Technology (Caltech) have identified the origin of olfactory nerve cells, finding that neural-crest stem cells — multipotent, migratory cells unique to vertebrates that give rise to many structures in the body — play a key role in building olfactory sensory neurons in the nose. When human noses detect a scent, two types of sensory neurons are at work. These neurons are...

Caltech-led team discovers enzyme responsible for neural crest cell development During the early developmental stages of vertebrates–animals that have a backbone and spinal column, including humans–cells undergo extensive rearrangements, and some cells migrate over large distances to populate particular areas and assume novel roles as differentiated cell types. Understanding how and when such cells switch their purpose in an embryo is an important and complex goal for...

Groundbreaking advancements described in Stem Cells and Development Researchers have successfully developed a stable population of neural crest cells derived from mice that can be grown in large quantities in the laboratory and that demonstrates the potential to develop into many different cell types needed throughout the body. This powerful new research tool for understanding stem cell biology and human development and disease is described in an article published in Stem Cells and...

Lack of regulator can cause neural tube defects Researchers at the University of Colorado School of Medicine have found that lack of a specific gene interrupts neural tube closure, a condition that can cause death or paralysis. "The neural tube is the beginning of the brain and spinal cord," said the study's lead investigator Lee Niswander, Ph.D., professor of pediatrics at the CU School of Medicine. "A defect in the mLin41 gene doesn't allow the tube to close because not enough neural...

In principle, stem cells offer scientists the opportunity to create specific cell types–such as nerve or heart cells–to replace tissues damaged by age or disease. In reality, coaxing stem cells to become the desired cell type can be challenging, to say the least. In a paper published this week in the journal Proceedings of the National Academy of Sciences, however, scientists at the University of Georgia describe a method that–in a single step–directs...

How is it that a disc-like cluster of cells transforms within the first month of pregnancy into an elongated embryo? This mechanism is a mystery that man has tried to unravel for millennia. The first significant step towards understanding the issue was made nearly a century ago in experiments conducted by the German embryologists Hans Spemann and Hilde Mangold. The two used early newt embryos and identified a group of cells within them which, upon transplantation, formed a two-headed...

During embryonic development, cells migrate to their eventual location in the adult body plan and begin to differentiate into specific cell types. Thanks to new research at the University of Pennsylvania, there is new insight into how these processes regulate tissues formation in the heart.  A developmental biologist at Penn's School of Veterinary Medicine, Jean-Pierre Saint-Jeannet, along with a colleague, Young-Hoon Lee of South Korea's Chonbuk National University, has mapped the...

Findings could one day lead to improved treatment of spinal cord injuries Scientists have discovered the origin of a unique type of cell known for its ability to support regeneration in the central nervous system. Their findings, published this week in the journal Proceedings of the National Academy of Sciences USA (PNAS), raise the possibility of obtaining a more reliable source of these cells for use in cell transplantation therapy for spinal cord injuries. Olfactory ensheathing cells...
