Discovery of a mechanism that regulates cell movement
... in the regulation of these movements is the amount of adhesive protein E-Cadherin located in the cellular membrane. Jordi Casanova, head of the morphogenesis
in Drosophila at IRB Barcelona, explains that "when movement starts, the levels of this protein in the cells decrease, thereby allowing them to slide ...
Early exposure to common weed killer impairs amphibian development
... period of development, organ morphogenesis.
Study Results Broadens Knowledge of Herbicide's Effects During a Vulnerable Stage
is a brief, extremely sensitive phase in the tadpoles' growth cycle when they are starting to develop organs, noted Kelly A. McLaughlin, Associate ...
Gene in male fish lures females into sex
... anal fins. "The two kinds of independently evolved egg-dummies serve as a model system to test whether the same genetic pathways are involved in the morphogenesis
of both types of dummies," say the authors.
Scientists explore how complex organs develop from a simple bud
... are revealed. The articles analyze how branching morphogenesis
occurs in different organ systems in the same ... autoimmune rejection. An investigation into the morphogenesis
of the prostate gland and seminal vesicles is ... Ultimately, scientists hope analysis of branching morphogenesis
will lead to the design of a computer program ...
Stowers scientists demonstrate mechanism of vertebral formation
... Snail proteins -- in the process of embryonic segmentation," said Robb Krumlauf, Ph.D., Scientific Director. "The findings provide a link between the morphogenesis
of the tissue that generates the vertebrae and the periodic production of their precursors."
The Snail factors which are known to control the ...
Clues to breast cancer hidden inside stem cells
... similar to what you have in vivo," says Gudjonsson.
"You can analyse cell-cell interactions and signaling pathways in these cells during morphogenesis
and in cancer progression." The Icelandic researchers are now focusing their efforts on how endothelial cells convey signals to stem cells in normal ...
Did feathered dinosaurs exist?
Feduccia, Lingham-Soliar and Hinchliffe found no evidence for the existence of protofeathers on dinosaurs and no evidence in support of the morphogenesis
of the feather from putative filamentous protofeathers. They suggest that 'protofeathers' described on fossil findings "are probably the remains of ...
Basis for DNA ejection from single phage particles
... built during packaging of the DNA in the phage capsid was responsible for DNA ejection. This pressure results from the condensation of the DNA during morphogenesis
?for example, another group recently showed that the pressure at the final stage of encapsulation for a particular bacteriophage reached a value of ...
