Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

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 ...

The new method offers researchers a powerful new platform to investigate the molecular mechanisms that control oogenesis, the process by which egg cells develop, and lays important groundwork for ...

Researchers have created a way to guide and control the development of stem cells into specific tissues and organs, opening the door to developing a means of one day tackling complex diseases like ...

The presence of an organelle called the fusome in species as diverse as Drosophila and mammals indicates an ancient, conserved programme of germ cell development.

Common conditions such as indigestion and heartburn as well as peptic ulcers, autoimmune gastritis and stomach and esophageal cancers have one thing in common – they involve disruptions of the normal ...

Cell sorting has become a key technique in modern biology, medicine, and biotechnology. Researchers use it to separate, analyze, and study different cell types with high precision. In this article, we ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...
