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 ...

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 ...

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 ...

University of Sydney researchers have developed a powerful way to test how closely lab-grown biological models resemble real human embryos, finding that while some models perform well, none yet fully ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

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 ...

Their “programmable” embryo-like structures, also known as embryoids, can be used to study the role of certain genes in early development The earliest days after fertilization, once a sperm cell meets ...

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 Scientists at Columbia University have ...
