Fig. 2. Expression dynamics of Hydra myc2 (A–D), CAD (E–H), and myc1 (I–L) during oogenesis.

Fig. 2.

Hydra myc2 is expressed throughout all stages of oogenesis. Transcriptional myc2 activation is apparent in proliferating and aggregating interstitial cell precursors contributing to formation of the egg field (A,B). Strong myc2 expression is detectable in the egg patch (C), and in the differentiating oocyte, which characteristically forms pseudopodia to take up nurse cells (D). CAD is expressed in proliferating and aggregating interstitial cells in early oogenesis (E). During formation of the egg field, CAD expression becomes restricted to the periphery (F,G). In the developing oocyte, CAD mRNA is absent but detectable in cells at the periphery (H). myc1 is not expressed in any cells contributing to oogenesis. Numbers indicate the oogenesis stages (Miller et al., 2000).
