Integrated screening and CRISPR reveal eleven previously unknown factors essential for early embryo development. They showed ...
Scientists used stem cells to create a model of an embryo in the lab without sperm or egg. The model embryo released the same hormones that trigger positive pregnancy tests. Researchers hope to use ...
(RNS) — Scientists have created a human embryo without the use of sperm or an egg — a true test-tube baby. Such embryos cannot (yet) develop into full-grown human beings. Even if transplanted into a ...
In a scientific breakthrough that raises a number of medical and ethical issues, researchers have used stem cells to create living, growing models of a human embryo. Because stem cells were used, ...
Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...
A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...
