recommendations! Published in 2019 at "Molecular Reproduction and Development"

DOI: 10.1002/mrd.23311

Abstract: Egg activation is the essential process in which mature oocytes gain the competency to proceed into embryonic development. Many events of egg activation are conserved, including an initial rise of intracellular calcium. In some species,… read more here.

DOI: 10.1089/cell.2016.0052

Abstract: Abstract Mammals are important for balancing the natural ecosystem, but in the past few decades, several species have rapidly been entered under threatened category worldwide. The environmental changes, loss of natural habitats, human activities, and… read more here.

DOI: 10.1371/journal.pbio.3003181

Abstract: Successful initiation of animal development requires activation of the egg immediately prior to fusion of gamete pronuclei. In all taxa, this is initiated by waves of calcium transients which transverse across the egg. Calcium waves… read more here.

DOI: 10.1530/rep-21-0480

Abstract: Mature amphibian eggs arrested at meiotic metaphase II must undergo activation to initiate embryonic development soon after fertilization. Fertilizing sperm provide eggs with a signal that induces egg activation, and an increase in intracellular Ca2+concentration… read more here.
