City-dwelling raccoons seem to be evolving a shorter snout—a telltale feature of our pets and other domesticated animals ...

Consider the crustacean Parhyale hawaiensis, a tiny crustacean with some interesting attributes. “It’s been called a ‘living Swiss army knife,’” said Dillon Cislo, the lead author of a study that ...

Embryonic development is a meticulously orchestrated process in which spatial and temporal cues guide cell fate determination and tissue patterning. Central to this process is morphogen signalling – a ...

A collection of studies that chart how mammalian brain cells grow and differentiate is a ‘very valuable’ tool for ...

The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that certain molecules that come with the sperm, so-called micro-RNA, contribute to ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Under the microscope, MSK scientists studied how cells in a mouse embryo (green) move out and break away from their original tissue by contracting their surfaces (red). Studying this process, known as ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children’s in Los Angeles has identified a mechanism by which embryonic cells ...
