New research on the teeth of fossilized dinosaur embryos indicates that the eggs of non-avian dinosaurs took a long time to hatch—between about three and six months. The study, led by scientists at Fl...
Characterization of the sperm factor responsible for initiating [Ca2+]i oscillations during fertilization in mammalian eggs
Biological sciences Sperm factor Oscillations Fertilization Mammalian eggs
2015/1/28
During fertilization the sperm activates the mammalian egg by eliciting [Ca2+]i oscillations. However, how the sperm triggers [Ca2+]i oscillations in mammalian eggs remains unknown. To test the possib...
