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.

Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

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

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.

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

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 ...

Arias’s group pretreated ESCs with an activator of a key signaling pathway and grew the cells in low-adhering conditions. 24 This promoted the cells to aggregate and form gastrulating embryo models, ...

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 ...

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 ...

“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 ...

The importance of cell compaction in embryo development Four days after fertilization, the 8 to 16 cells that compose the embryo move closer together to give the embryo its initial shape. During ...
