Figure 4. The BMP pathway is highly activated in ectopic GSCs caused by misexpression of Ken in the CySC lineage.
(A, B) Confocal section through testis immunostained with anti-Tj (red), anti-pMad (green), and DAPI (blue). High levels of pMad indicative of BMP pathway activation accumulate in ectopic GSCs in ZFH1 misexpressing (A) and Ken misexpressing (B) testes. Scale bar, 20 m.
