These authors show that fibroblast growth factor (FGF) signalling regulates cilia length and function in diverse epithelia during zebrafish and Xenopus development. They propose that some ...

Because of its large eggs, Xenopus laevis -- the African clawed frog -- has become a popular model for studying embryo development and cell biology. It's smaller cousin, X. tropicalis, is now ...

To determine if this study's findings are indeed unique to the avian embryo, Zamir plans to conduct further studies to characterize protein expression and cell migration in Xenopus and zebrafish.

Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into the early stages of embryonic ...

During each week of pregnancy, your baby is growing. Here’s a look at what medical terms like embryo and fetus mean in terms of development.

Morphogens are the secreted molecules that pattern embryonic tissues. These molecules are important not only for the embryo during development, but also for the adult during tissue repair. However ...

Researchers created an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of embryonic development that may provide ...

Morphogens are molecules that travel from biological cell to cell to pattern tissues in the embryo. These molecules are important not only for the embryo during development, but also for the adult ...

Many top UK scientists are calling for the current 14-day limit on embryo research to be doubled to 28-days, so they can study the unexplored secrets of early human development. Lifting the ban ...

A team of researchers in the United States and United Kingdom say they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm.
