How the simple symmetry and its breaking evolves during the growth of the embryo is intriguing.

But a salamander embryo can attract algae. Inside its tissues and cells.

Normally, the neural crest cells crawl through the embryo and form a strip running along the back.

This logarithmic increase suggests that algae associated with the salamander embryos either divide rapidly as the embryo develops, or quickly enter the jelly or the embryo from outside as it grows.

First, the heart of an embryo starts off as a little tube, similar to the heart of a goldfish.

Every month, the uterus builds up a lining of tissue called the endometrium, where an embryo can implant and grow.

The middle germinal layer of an early embryo, consisting of undifferentiated cells destined to become the mesoderm.

Methods Hepatocytes obtained from the new born rabbit were cultured on the AGAR scaffold made up of AGAR, embryo cattle strum and antibiotics, then observed the growth and proliferation of the cells.

A handful of genes that are normally active in the developing embryo are expressed in a differentiated cell, such as a skin cell, causing that cell to revert back to its undifferentiated state.

From the curl of a ram's horn to patterns of spider webs and the development of an embryo, Mr Ball examines the possible causes of the shapes and forms we observe.
