As the debate continues on the ethics and therapeutic potential of embryonic versus mature stem cells, Medical College of Georgia researchers are exploring a third group of cells that appears critical to development and capable of making all major types of human tissue.
"VENT cells are a unique category of multi-potent cells," Dr. Douglas P. Dickinson, molecular biologist, says of this cell type that escapes from the bottom of the neural tube early in development, after the tube closes to form the brain.
VENT cells then travel along nerve paths, eventually getting ahead of the nerves, and dispersing throughout the body. "They travel in association with the cranial nerves to target tissues, disperse into those tissues, then, at what is perhaps an endpoint for their stay during development, they differentiate into the same cell type as their neighbors. So they potentially just vanish into the crowd," says Dr. Dickinson who first heard of these cells last year when their discoverer, MCG Developmental Biologist Paul Sohal, gave a lecture at the MCG School of Dentistry. Dr. Dickinson thought these cells might be used to establish a human cell line to enable his studies of the development and function of salivary glands.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
