Figure 1: Retinoic-acid signalling is uniform across the left–right axis and present only in node ectoderm. Figure 2: Bilateral somite-size defects precede left–right defects in the absence of ...

Researchers have discovered that microRNAs play an important role in embryonic development. The study pinpoints two microRNA families that direct the allocation of cells into the three germ layers -- ...

Until now, adherence was thought to be the principle force responsible for the separation of the ectoderm from the mesoderm in embryonic cells. But by using high resolution imaging, researchers have ...

Paediatric head and neck teratomas are rare and present diagnostic challenges. We report a case of a toddler with a recurrent growth in her upper jaw, initially removed at birth and diagnosed as ...

Corals first appeared on earth nearly half a billion years ago during the Cambrian Period of the Paleozoic Era. The ancient Greek philosopher Aristotle categorized corals as zoophyta, or ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

Neuroepithelial cells are stem cells that differentiate into neurons and glia, essential components of the human central nervous system, following the process of neurogenesis. Also known as ...

Scientists have created a scalable 3D organoid model that captures key features of early limb development, revealing how a ...
