(A) Phase II simulation output at 3600 MCS (= E18.5) shows oocytes (red) in germ cell
nest structures and some primordial follicle structures. Cell types: oocytes (red),
granulosa cells (blue), somatic cells (yellow), epithelial cells (green), and
mesonephros (gray). (B) Experimental image of a developing E18.5 mouse ovary show
oocytes (red) stained for TRA98, granulosa cells (green) stained for FOXL2, and DAPI
(blue) nuclear counterstain. (C) Another experimental image of a developing E18.5
mouse ovary show oocytes (cyan) stained for TRA98, interstitium (green) stained for
αSMA, somatic cells (red) stained for WT1. [A colour version of this figure is
available in the online version.]
