KLP38B mRNA is found in proliferating cells. (A) Dorsal view of brain from third instar larva. KLP38B transcripts are detected in the inner and outer proliferative centers of the optic lobe and in scattered cells, probably neuroblasts, elsewhere on the optic lobe. (B) Eye-antennal disk from third instar larva. KLP38B transcripts are seen in the proliferative regions: the antennal disk, the most anterior region of the eye disk, and in a broad stripe just behind the morphogenetic furrow. Orientation: posterior is up. (C) Testis from late (dark) pupa. KLP38B transcripts accumulate during the 90-h growing phase when the primary spermatocytes grow before meiosis and are degraded shortly after meiosis.
