Using the blastocyst complementation method, we produced rat embryonic stem (ES) cell-derived sperm in testicular hypoplasia mice and successfully generated rat offspring. This method can provide a ...

Researchers have identified Nr1h2, a critical transcription factor essential for early embryo development. Their findings enhance our understanding of gene regulation during blastoid formation and ...

Embryonic stem cells (ES cells or ESCs) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage ...

Please provide your email address to receive an email when new articles are posted on . The 3D imaging model achieved more than 90% accuracy in identifying blastocyst features. Blastocyst overall ...

Embryonic stem cells (ESCs) are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4 th to 7 th day after fertilization. In normal embryonic ...

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 ...

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother. This mechanism to temporarily slow ...

SINGAPORE – Researchers from the A*STAR Institute of Molecular and Cell Biology (IMCB), led by Dr Jonathan Yuin-Han Loh, have identified Nr1h2, a critical transcription factor essential for early ...
