Conditional genetics and single-embryo RNA-seq show that SETDB1 extinguishes the transient, retroelement-driven transcriptional programs of the totipotent two-cell state to facilitate the exit from ...

Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize ...

Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an ...

BEIJING -- After years of dedicated research, a team of Chinese scientists has unveiled critical mechanisms governing early human embryonic development, offering novel theories and potential ...

Researchers at Vanderbilt University have developed a new embryo culture dish that significantly improves microscope imaging, a longstanding barrier in in‑vitro fertilization (IVF). Traditional 3D ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Scientists interrogate leftover culture media to noninvasively determine the quality of embryos in the lab, providing a way to better predict in-vitro-fertilization (IVF) success. Researchers at the ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

Selecting the healthiest embryo is one of the most important steps in in‑vitro fertilization (IVF), yet it remains one of the ...
