From: Unfertilized frog eggs die by apoptosis following meiotic exit
Spontaneous meiotic exit in unfertilized Xenopus eggs. Changes in the morphology of water-deposited (a) and OR-2 buffer-deposited (b) eggs, major morphological types of the unfertilized eggs (c-h), MAPK dephosphorylation and cyclin B2 degradation (i, j), and H1 kinase activity of Cdk1 in water-deposited and buffer-deposited eggs (k) are presented. Time after egg ovulation (hours) is indicated.
