Scientists have developed a new method that can manipulate the movement of embryonic cells using short-time attractors. As embryos grow from conception to birth, cells multiply rapidly and move in a ...

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, ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants. A study by UT ...

A test deployed in many fertility clinics to assess the viability of embryos for use in IVF is likely to overestimate the number of embryos with abnormalities, suggests a study published today. Using ...

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 ...

Researchers relied on a newer gene-editing technique that may make it possible to engineer embryos, a prospect that has long alarmed bioethicists. By Carl Zimmer See more of our coverage in your ...

Successful fertility treatments, including in vitro fertilization (IVF), is often reliant on a clear understanding of developmental stages of human development. Clinicians working with assisted ...
