A molecular pathway known for controlling cell shape and movement also helps regulate the rhythm by which the vertebrate body ...

Stem cell-based embryo models (SCBEMs) offer new ways for studying early human development while circumventing ethical challenges associated with natural embryos. Traditionally, SCBEMs are categorised ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

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 ...

UC Riverside researchers report vanillin knocks early human stem cells off course at trace doses.

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 ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Vanillin, a common flavoring chemical in e-cigarettes, may disrupt the normal development of embryos in pregnant women who ...

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 ...
