How did the characteristic pattern of embryonic cell divisions during animal development evolve? Analysis of the multicellular development of an organism related to animals now provides some answers.

These observations suggest that the genetic programs responsible for embryonic development were already present before the emergence of animal life, or that C. perkinsii evolved independently to ...

The emergence of multicellular life roughly 700 million years ago was a pivotal event that shaped the evolution of life on ...

In a remarkable medical breakthrough, doctors have successfully used stem cells to treat a debilitating eye condition that ...

Eyes affected by aniridia have difficulty adjusting to light, resulting in blurry vision and light sensitivity. Aniridia is caused by mutations in the PAX6 gene. This gene plays an important role in ...

Nov. 26, 2024 — Scientists have shed new light on how certain biological processes determine the development of neural cells. Their findings on a molecular 'bridge' complex demonstrate a new ...

In this stage, the rotation process is complete, and the eyes begin to show a light grayish pigmentation. In general, the embryonic development during the incubation process of fertile eggs of ...

Scientists have reprogrammed mouse cells into pluripotent stem cells using a gene from choanoflagellates, single-celled ...

Dr Minger said: "We are very excited about this development. Human embryonic stem cells are found in the earliest stages of development and are capable of giving rise to all the different types of ...
