Figure 4From: Changes in the reproductive function and developmental phenotypes in mice following intramuscular injection of an activin betaA-expressing plasmidHistology of the gonad. The ovaries (A) and testis (B) were prepared as described in methods and observed at 40 × (A; Above, B) and 120 × (A; Below) magnification. Of note is that follicle revealed a thickened granulosa cell layer with a small antrum and increased numbers of corpora lutea were observed in the pCMV-rAct-injected female mouse. Asterisks indicate antra in the follicles of control mice.Back to article page
