Inhibition of lin-4 with Rhdextran-(as-2'OMelin-4 )
led to retarded development. (a, b) Control young adult animals (~ 55 h post-hatching) showed normal alae [(a) highlighted by arrow heads] and col-19::GFP expression [(b) top - bright field; bottom - green fluorescence protein (GFP)]. (c-f) Young adult animals (~ 55 h post-hatching) labelled with Rhdextran-(as-2'OMelin-4)1 (50 μM injection concentration) displayed no alae (c) or col-19::GFP (d). 10 hours later (~ 65 h post-hatching), both alae (e) and col-19::GFP (f) appeared in these animals. Scale bar = 0.1 mm.
