Amphibian embryos exhibit remarkable hatching plasticity, enabling them to adjust the timing of hatching in response to environmental cues, particularly those signalling predation risk. This adaptive ...

A new research paper was published in Aging (Aging-US) Volume 17, Issue 3, on March 5, 2025, titled "Reproductive aging, preimplantation genetic testing for aneuploidy, and the diameter of blastocysts ...

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 ...

It’s challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That’s why many mammalian embryos can postpone their growth to get through periods of environmental ...
