Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...

In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

Scientists show how a fertilized egg cell, or zygote, hits 'reset' so that the newly formed embryo can develop according to its own genetic program. New work by scientists in the U.S. and China shows ...

(RNS) — Scientists have created a human embryo without the use of sperm or an egg — a true test-tube baby. Such embryos cannot (yet) develop into full-grown human beings. Even if transplanted into a ...

REHOVOT, Israel (Reuters) - 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 ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Researchers at University of Tsukuba have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, ...
