Fig. 3. Effect of DjPum RNAi on regeneration in D. japonica.
Brightfield images of the injected organisms. Dorsal view, anterior is towards
the top. Broken yellow lines indicate the blastema region. (A) A head fragment
injected with DjPum dsRNA. (B) A water-injected head fragment, 4 days
after the second transection. (C) A tail fragment injected with DjPum
dsRNA, 4 days after the second transection. (D) A water-injected tail
fragment, 4 days after the second transection. (E) A head fragment injected
with DjPum dsRNA, 14 days after the second transection. (F) A tail
fragment injected with DjPum dsRNA, 14 days after the second
transection. (G) Visualization of a comparative RT-PCR experiment in
planarians injected with DjPum dsRNA, water and Djeya dsRNA.
DjEF2 is used as an internal amplification control. Scale bars: 250
