(M-P)
nhr-208 reporter expression in a 1.5-fold embryo, L1, L2, and adult male tail (ventral view), respectively. Expression was seen in the intestinal sphincter and posterior epidermal cells during embryogenesis. By L1, unidentified head neurons and strong posterior intestinal expression were observed. Expression was also seen in the intestinal-rectal valve cell (O) and in male specific neurons and rays. Scale: 20 um.
