Researchers Discover How To Change Cell Types By Flipping A Single Switch
2013-12-04 13:05:09

University of California - Santa Barbara With few exceptions, cells don't change type once they have become specialized — a heart cell, for example, won't suddenly become a brain cell. However, new findings by researchers at UC Santa Barbara have identified a method for changing one cell type into another in a process called forced transdifferentiation. Their work appears today in the journal Development. With C. elegans as the animal model, lead author Misty Riddle, a Ph.D. student...

A team of Massachusetts General Hospital (MGH) investigators working to create "protocells" – primitive synthetic cells consisting of a nucleic acid strand encased within a membrane-bound compartment – have accomplished an important step towards their goal. In the November 28 issue of Science, the investigators describe a solution to what could have been a critical problem – the potential incompatibility between a chemical requirement of RNA copying and the stability of the protocell...

Tokyo, Nov 25, 2013 - (ACN Newswire) - Researchers at Waseda University in Japan have for the first time directly observed the "molecular motor", called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. Their findings are expected to contribute greatly to elucidating the molecular mechanisms of chromosome segregation, a key aspect of the development of certain medical disorders including cancer and birth defects.A human being begins as...

Clay May Have Been Cradle Of Life
2013-11-08 11:08:34

[ Watch the Video: Life On Earth May Have Come From Clay ] Brett Smith for redOrbit.com - Your Universe Online Often viewed as an apparently infertile blend of various minerals, clay might have actually been the birthplace of life on Earth, biological engineers from Cornell University report in new research appearing in Thursday’s online edition of the journal Scientific Reports. The study authors set out to simulate ancient seawater in order to analyze the properties of clay under...

A crucial component of wound healing in many animals, including humans, is the migration of nearby skin cells toward the center of the wound. These cells fill the wound in and help prevent infection while new skin cells regenerate. How do these neighboring skin cells know which way to migrate? What directional cues are they receiving from the wound site? A new paper by Mark Messerli and David Graham of the MBL’s Eugene Bell Center for Regenerative Biology and Tissue Engineering clarifies...

Researchers Explain The Flagellar Synchronisation Of Swimming Algae
2013-10-25 14:14:45

Max Planck Institute The beating of flagella is one of the basic principles of movement in the cellular cosmos. However, up to now, scientists were unsure as to how the movements of several of these small cellular appendages are synchronized. Dresden-based researchers from the Max Planck Institute of Molecular Cell Biology and Genetics and the MPI for the Physics of Complex Systems have now succeeded in demonstrating how the green alga Chlamydomonas synchronizes the movements of its two...

Clarified role of signal-relay proteins may help explain spread of cancer Cell biologists at The Johns Hopkins University have teased apart two integral components of the machinery that causes cells to move. Their discovery shows that cellular projections, which act as hands to help a cell "crawl," are apparently always initiated by a network of message-relaying proteins inside the cell. It was already known that in directional movement, the network is activated by sensor proteins on the...

Cell (journal)
2012-06-04 14:15:36

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 &...
