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 ...

or embryo, generates the cells, tissues, and organs of a new individual and assembles them into their proper form. Evolution produces the body shapes of the animal kingdom; development produces ...

While some animals like mammals have a limited ability to regenerate lost tissues, planarians can be cut roughly in half and ...

Studying the early development of human embryos is challenging due to ethical constraints and technical difficulties.

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development.

New research shows Glycolysis -- the process of converting sugar into energy -- plays a key role in early development. More than fuel, Glycolysis doesn't just power cells -- it helps steer them toward ...

As governments and industry move to ban the culling of male chicks, a central question continues to shape public policy, research funding and ethical debates: When can a chick embryo feel pain?

As well as providing energy to the cell, glycolysis also controls cell fate in early embryonic development, laying the ...

During early embryonic development, cellular signals dictate that we should be built with two sides, a top and bottom, and a front and back. But what genes create these signals, and how do they work?

For some animals, the entire process of cellular ... They targeted regions of the genome known to be involved in the development of an early embryo. This allowed them to control which genes ...

It is also the only small animal that, in females ... signalling pathways to see how these genes could affect embryo development” she said. “When we compared the development of the guinea ...

A new study reveal for the first time that the guinea pig pre-implantation embryo is very similar to the human embryo, ...
