Figure 7. Ptp61F expression in the Drosophila testis apex.
(A, B) In situ hybridization on wild-type testes. (A) Ptp61F mRNA is expressed at low levels around the niche (in the hub, GSCs, and CySCs), and is greatly upregulated in differentiating germ cells and somatic cells. (B) Ptp61F sense probe is shown as a negative control. Scale bar, 10 m.
