| Type | In_situ | In situ hybridization with sense and antisense daf-21 DIG-labeled RNA probes | ||
| Pattern | In adult males, daf-21 mRNA was detected in germline cells, similarly as in hermaphrodites, with a strong signal seen in spermatogonia, decreasing signal in spermatocytes, and none in mature sperm. | |||
| In the embryo comma stage, daf-21 mRNA was strongly detected in cells of the head region and less so in other areas. In the hatched L1 larvae, daf-21 mRNA was mainly distributed in the germline precursor cells Z2 and Z3 and the head region, whereas in the adult hermaphrodite, it was localized uniquely in the germ cells. In the distal arms of the adult hermaphrodite, mitotically dividing germline cells were strongly stained with the antisense probe, but not with the sense probe. As the oocytes matured, the signal strength of the antisense probe seemed to decrease. | ||||
