University of Sydney researchers have developed a new way to test how closely lab-grown biological models resemble real human ...

For years, scientists have grown ball-like structures from human stem cells that mimic some of the earliest stages of ...

Before most women know they're pregnant, an embryo has already begun organizing itself into the structures that will shape a developing body. Scientists have few opportunities to study those earliest ...

For years, the dream of correcting disease-causing DNA in human embryos has been shadowed by a hard biological reality: the ...

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 ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

The team mapped the spatial and temporal patterns of glucose uptake using single-cell-resolution imaging of developing mouse embryos, stem cell models, and embryo-derived tissues. They found that the ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

In in vitro fertilization treatment, it is known that when pregnancy is desired at an older age, the incidence of chromosomal ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...
