In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

Research with human embryos and embryo models, this year’s Method of the Year, can be fraught. In contrast, digital embryos could be studied, even perturbed, in computational what-happens-when ...

Embryo selection in assisted reproduction has traditionally relied on subjective morphological grading, which is prone to inter-observer variability and correlates poorly with ploidy, the primary ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

The earliest stages of developing life have been, in many ways, a black box for researchers before now. A human blastoid is an embryo model formed from stem cells that laboratories have used to study ...

New research by a scientist at the Milner Center for Evolution at the University of Bath suggests that "selfish chromosomes" explain why most human embryos die very early on. The study, published in ...

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 ...
