Using the common fruit fly, researchers at UT Southwestern Medical Center have discovered that an intricate set of signals released by stem cells surroundings governs their maintenance.
These findings, available online and in todays issue of Current Biology, will aid stem cell researchers in understanding and potentially manipulating the delicate environments that promote adult stem cell formation, said Dr. Dennis McKearin, associate professor of molecular biology and associate dean for the Medical Scientist Training Program at UT Southwestern and senior author of the study. "We want to understand the biochemistry behind stem cells that distinguishes them from other types of cells," Dr. McKearin said. "This work aids in understanding general stem cell biology."
The reproductive system of the female fruit fly, as in humans, contains a reservoir of adult stem cells. When the stem cells divide, they create two daughter cells, each with a distinct fate. One daughter travels away from the reservoir, divides further, and eventually becomes the egg and nurse cells, which nourish the egg.

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...
