During animal development, cells divide and arrange themselves in a coordinated way, eventually forming the embryo. The cells ...

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

Scientists combined 120 of these cells in a precise ratio, mixed them in a shaker, and then watched to see what developed — and soon, an embryo-like structure formed spontaneously.

Stem cell biologist Jacob Hanna, a 2024 STATUS List member, says embryo models can be handled ethically, and can lead to advances in organ transplantation.

“We want to know how cells organize themselves into an embryo-like model, and what could go wrong when there are pathological conditions that prevent an embryo from successfully developing.” Cell ...

Our stem-cell-derived human embryo model offers an ethical and accessible way of peering into this box. It closely mimics the development of a real human embryo, particularly the emergence of its ...

In some new research featuring wondrous video of the cricket embryo — showing certain “right parts” (the cell nuclei) moving in three dimensions — Dr. Extavour, Dr. Donoughe and their ...

A stem-cell derived human embryo model showing blue cells (embryo), yellow cells (yolk sac) and pink cells (placenta). Scientists have grown an entity that closely resembles an early human embryo ...

Lab-engineered human embryo models created from stem cells provide a look at development beyond the first week. But they raise ethical questions.

REHOVOT, Israel, Sept 7 (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 ...
