...oRNA miR-1-1 could not fully compensate for loss of miR-1-2. The team found that loss of miR-1-2 affected many functions in the heart, including heart morphogenesis and control of the number of cells in the heart. For example, half of the mice developed holes in the pumping chambers of the heart, which is the most...Mystery behind the Formation of Vertebral Precursors Unraveled

The findings bridge the gap between the morphogenesis of the tissue that generates the vertebrae and the periodic production of their precursors. Various studies would help in appreciating their function ...Mechanical forces drive early heart development
...o show that biomechanical forces may be as important as genetics in shaping the heart.// Recently, he has developed a theory on tissue growth and morphogenesis (shape change) and applied it to understanding the developing heart in chicken embryos, which is remarkably similar to its counter-part in human. Tabe...Discovery of a mechanism that regulates cell movement
...lement 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

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.
