Comparison of reproductive glands by TEM between 42-day-old adult worms in the NC group vs. S1 siRNA group (10 injections via the tail vein at 4–42 dpi). SjFrzb2-S1 siRNA-induced alterations of the reproductive system are obvious. A Normally developed males exhibited greater numbers of spermatocytes, with chromatin around the nuclei. B The spermatocyte number was decreased, and the abundance of intracellular chromatin was reduced in the siRNA-treated groups. C, E Normally developed females presented mature vitelline cells, with regular cell edges and large numbers of vitelline droplets and globules. D, F Females in the siRNA-treated groups presented developmentally immature vitelline cells with fewer vitelline droplets and globules. vc: vitelline cells, vg: vitelline globules, vd: vitelline droplets, l: lipid droplets, n: nucleus, nu: nucleolus, s: spermatoblast.
