Eventually, the light-sensitive spot evolved into a retina, the layer of cells and pigment at the back of the human eye. Over time a lens formed at the front of the eye. It could have arisen as a ...

In Greek mythology, a chimera is a grotesque hybrid. But chimeras are not just tales. Here's how some scientists have been ...

A team led by Mount Sinai researchers has identified stem cell populations and mechanisms underlying age-related degeneration ...

The researchers plan to refine the protocol and test against cells in photoreceptor degeneration that are more closely related to the human eye. If practical, they hope to start clinical trials.

Researchers from London's Moorfields Eye Hospital, biotech firm MeiraGTx and University College London have demonstrated that ...

This shows the optician the blood vessels on the surface of the retina and the light-sensitive cells. A human eye has more than a million light-sensitive cells. Students could explore how their ...

They are far more sensitive to light than cone cells, which is why you can sometimes see stars out of the corner of your eye at night, but when you look straight at them they seem to disappear. 5.

That's when we went down the path of proving that they were actually T cells for this study.” To do so, the authors performed Fun-IVCM on healthy human subjects and compared the morphology and ...

A robotic device allows eye surgeons to perform high-precision procedures on the retina, the fragile lining on the back of the eye that is less than a millimeter thick.

Glucocorticoid (GC) treatment of human trabecular meshwork (HTM) cells produces delayed, progressive cellular and extracellular protein/glycoprotein inductions with characteristics matching those ...
