During the tightly regulated gastrulation, embryonic cells differentiate into the three germ layers – endoderm, mesoderm, and ectoderm – which eventually give rise to all tissues and organs.
A gathering of the world's stem-cell scientists in Toronto this past week made it clear that working with these embryonic mimics has turned out to be trickier than expected.
Scientists have been all abuzz in the last few years over stem cells — cellular magicians that promise to dazzle and amaze. In December 1999, the editors of Science, the journal devoted to ...
A newly created cell model of the amniotic sac could reveal new insights into early pregnancy, as well as generate helpful ...

Cell contractions drive the initial shaping of human embryos Date: May 1, 2024 Source: CNRS Summary: Human embryo compaction, an essential step in the first days of an embryo's development, is ...
Embryonic macrophages - specialized phagocytes of the immune system - influence the formation of blood stem cells in the bone marrow and thus the lifelong production of blood cells.
In the early stages of human embryonic development, a zygote divides into two identical totipotent cells that eventually become eight cells. 1 Cell fate decisions begin to differentiate this ...
