Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early ...

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 ...

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 ...

Unlike humans, turtles, lizards and other reptiles – such as crocodiles – do not have sex chromosomes. Their sex is determined based on the environment, which makes them especially vulnerable to ...

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 ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

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 ...

image: One of the significant challenges in sex reversal research is the lack of an in vitro system to model and study variants found in Disorders of Sex Development (DSD) individuals. A study ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

Which genes are required for turning embryonic stem cells into brain cells, and what happens when this process goes wrong? In ...

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 ...
