A new study show that whole-body regeneration involves transcriptional changes in cells from all three germ layers (muscle, epidermis, and intestine) of the body, and that tissue from areas distant ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

A group of scientists at the Cincinnati Children's Hospital has used separate lines of human induced pluripotent stem cells (iPSCs) to create stomach organoids with a three-layered structure and ...
