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 ...

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 ...

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 ...

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 ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

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 ...

Researchers have identified Nr1h2, a critical transcription factor essential for early embryo development. Their findings enhance our understanding of gene regulation during blastoid formation and ...

Genes are transcribed from DNA into RNA, which is then processed in various ways before being translated into proteins. RNA molecules get edited or spliced, and certain sequences might be removed ...
