Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.

Very small embryonic-like stem cells (VSELs) are a rare and intriguing subpopulation of adult stem cells that exhibit molecular signatures reminiscent of embryonic stem cells. Identified in various ...

Researchers have succeeded in generating high-quality feline embryonic stem cells using sperm and eggs from testes and ovaries discarded during sterilization surgery. As different as they may seem, ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as ...

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 ...

Dlc1 deletion affects cardiac differentiation in mouse embryonic stem cells by activating the canonical Wnt pathway ...

Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids, but ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ...

The research represents a major step forward in revealing how the three dimensional form of DNA shapes the way human biology functions. In a major step toward understanding how the physical form of ...
