The planarian flatworm Schmidtea mediterranea develops its entire reproductive system post‐embryonically from a population of adult somatic stem cells. Counts et al. (this issue) assessed the requirement of different chaperonin CCT/TRiC subunits during spermatogenesis and somatic integrity using RNA‐interference, which allows for the genetic assessment of specific components during oogenesis and spermatogenesis in this organism. Shown here is a sexually mature planarian (S. mediterranea), imaged by dark‐field microscopy, overlaid on a confocal image of the interior of an individual testis lobe in which the nuclei of cells during various stages of spermatogenesis are revealed .
