The creation of artificial embryos has moved a step forward after an international team of researchers used mouse stem cells to produce artificial embryo-like structures capable of ‘gastrulation’, a ...

Study reveals that genomic nuclear speckle-associated domains (SPADs) are step-wise organized during mouse early embryogenesis, with key factors contribution in this process. Following mammalian ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

New research tracks how cells prepare gene regulatory decisions that will define their fate during the earliest stages of ...

Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize ...
