Fig. 8. Expression of dpp and a Wnt reporter change during aging.

Fig. 8

RNA in situ hybridization of dpp was performed on germaria from females (A) aged for 4 days or (B) for 28 days. The level of dpp transcripts decreased in the cap cells and increased in the escort cells upon aging. Wnt reporter expression exhibits the opposite pattern with an increase of Wnt activity in the cap cells and a reduction in the escort cells in the germaria of old females (D) compared to young females (C). The number of germaria exhibiting Wnt activity either in the terminal filament (TF) and the cap cells or in the escort cells was scored in 4 day, 28 day and 35 day-old females (E). (Scale bars, 10 μm).
