Scientists created a blastocyst-like structure – an early embryo – using mouse stem cells instead of sperm and egg.

Researchers have generated 3D blastocyst-like structures from stem cells. The study shows that the blastocyst-like structures very closely resemble actual blastocysts, and even induce proper ...

This report, first published online on March 3, 2004, discusses the procedures used to develop 17 lines of human embryonic stem cells from the inner cell masses of blastocysts. These cell lines are ...

An international collaboration of researchers from the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan and Gladstone Institutes in the U.S. have generated 3-D blastocyst-like ...

The stem cell-based embryo model (SCBEM) takes advantage of the flexibility of pluripotent stem cells (non-reproductive cells ...

This mechanism to temporarily slow development, called embryonic diapause, often happens at the blastocyst stage, just before the embryo implants in the uterus. During diapause, the embryo remains ...

Two-cell mouse embryos cultured on the International Space Station and returned to Earth formed blastocysts (some shown). S. Wakayama et al/iScience 2023 ...

Prior to implantation, an embryo is a ball of about 250 cells organized as a blastocyst. This elusive ball of cells was difficult to study directly, so scientists developed blastoids - stem-cell ...

Around six to seven dpf, the blastocyst implants into the surface of the uterine wall and begins its expansion. 4 This area of the endometrium is transformed early on in pregnancy and acts as a fluffy ...

Blastocysts are normally protected from external influences by a coat, the zona pellucida; before the embryo implants in the ...
