The birth of vision from the retina to the brain

How is the retina formed? And how do neurons differentiate to become individual components of the visual system? By focusing on the early stages of this complex process, researchers at the University of Geneva (UNIGE), Switzerland, ...

Mechanical forces control cell fate during brain formation

A new study coordinated by the Research Group in Developmental Biology at UPF shows that during the embryonic development of the brain, the cells that are between adjacent segments detect the mechanical forces generated during ...

Cell-cell signals in developing heart

During late stages of heart development, interactions between the endocardium (the inner layer of cells) and the myocardium (the heart muscle) are known to be crucial. Signaling between these two cell layers during the earliest ...

Neurons migrate in the nascent brain as if on rails

Researchers examined the brain development of mouse embryos. They concentrated on a pool of neuronal precursor cells that develops in the hindbrain about ten days after fertilization. These mature into nerve cells and then ...

Cellular 'tuning mechanism' builds elegant eyes

How different cells in a multicellular organism acquire their identities remains a fundamental mystery of development. In the eye, for example, the lens contains two cell types—lens epithelial cells and lens fiber cells—the ...

Amputation injury is communicated to opposing limbs

In research that extends knowledge about the physiology of regeneration and wound repair, Tufts University biologists have discovered that amputation of one limb is immediately reflected in the bioelectric properties of the ...
