Picture from Ghosh S et al. (2016) MicroPubl Biol "ina-1 expression in the somatic gonad during late larval development."

ina-1 is expressed throughout uterine toroids. (A) At mid L4, expression is seen in uterine toroid 1 and 4 (ut1, ut4) and in the anterior uterine toroids 2 and 3 (ut2, ut3). In addition, ina-1::GFP is detected in the spermathecal-uterine junction and spermatheca. (B) At the L4 lethargus stage, bright expression is observed in uterine toroids 1 and 4, the spermathecal-uterine junction, and spermatheca. Dimmer expression is present in uterine toroid 2 and posterior toroid 3. Fluorescence is also detected in vulE. Anterior to the left, dorsal top. Scale bar 100 um. - Reviewed by Bhagwati Gupta.
