Finding promises to streamline creation of therapeutic cells Despite the promise associated with the therapeutic use of human stem cells, a complete understanding of the mechanisms that control the fundamental question of whether a stem cell becomes a specific cell type within the body or remains a stem cell has–until now–eluded scientists. A University of Georgia study published in the March 2 edition of the journal Cell Stem Cell, however, creates the first ever blueprint...

Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells. The study proposed a new model to explain how mammalian cells establish the sense of direction necessary to move, as well as the mechanism that a disease-causing form of E. coli bacteria employ to hijack that ability. Cells need to orient...

In recent years, a number of controversial claims have been made about the female mammal's egg supply — that it is renewed over her adult lifetime (as opposed to the conventional understanding that she is born with all of her eggs), and that the source of these eggs is stem cells that originate in the bone marrow. Now, Weizmann Institute scientists have disproved one of those claims and pointed in new directions toward resolving the other. Their findings, based on an original method for...

Lipids help control the development of cell polarity In a standard biology textbook, cells tend to look more or less the same from all sides. But in real life cells have fronts and backs, tops and bottoms, and they orient many of their structures according to this polarity explaining, for example, why yeast cells bud at one end and not the other. Over the last few years, Rong Li, Ph.D., and her team at the Stowers Institute for Medical Research have figured out many important details of...

To solve a mystery, sometimes a great detective need only study the clues in front of him. Like Agatha Christie's Hercule Poirot and Arthur Conan Doyle's Sherlock Holmes, Tomomi Kiyomitsu used his keen powers of observation to solve a puzzle that had mystified researchers for years: in a cell undergoing mitotic cell division, what internal signals cause its chromosomes to align on a center axis? "People have been looking at these proteins and players in mitosis for decades, and no one ever...

Small molecules at the cell's membrane enable cell movement Cell biologists at Johns Hopkins have identified key steps in how certain molecules alter a cell´s skeletal shape and drive the cell´s movement. Results of their research, published in the December 13 issue of Science Signaling, have implications for figuring out what triggers the metastatic spread of cancer cells and wound-healing. “Essentially we are figuring out how cells crawl,” says Takanari Inoue,...

Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford University School of Medicine. The finding is an extension of a previous study by the same group showing that mouse and human skin cells can be directly converted into functional neurons. The multiple successes of the direct conversion method could refute the idea that pluripotency (a term that describes the ability of stem cells to become...

In a study that holds major implications for breast cancer research as well as basic cell biology, scientists with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, which the researchers call “CAMo,” for coherent angular motion, is necessary for the cells to...

Visualization of the molecular gateway across and into cellular membranes All living organisms are made up of cells, behind these intricate life forms lie complex cellular processes that allow our bodies to function. Researchers working on protein secretion – a fundamental process in biology – have revealed how protein channels in the membrane are activated by special signals contained in proteins destined for secretion. The results help explain the underlying mechanism...

Study of plant hormone could have far-reaching implications for cell biology and disease research A recent Van Andel Research Institute (VARI) study published in the journal Science investigating the molecular structure and function of an essential plant hormone could profoundly change our understanding of a key cell process, and might ultimately lead to the development of new drugs for a variety of diseases. The study builds on earlier work by the same team of investigators at VARI...

Cell is a peer-reviewed scientific journal founded by Benjamin Lewin in January 1974 with the sponsorship of MIT Press. Lewin bought the rights to the journal in 1986 and published it under his own publishing arm Cell Press. Cell Press was sold to Elsevier in 1999, which currently publishes Cell twice monthly. Cell Press publishes several biomedical journals, including Cell, Neuron, Immunity, Molecular Cell, Developmental Cell, Cancer Cell, Current Biology, Structure, Chemistry &...
