The Hit Compounds Increase Regeneration, Not Survival, of β Cells

(A) Schematic diagram for cell labeling and assessment of β cell survival/regeneration. To examine β cell survival, we made use of the photoconvertible property of the fluorescent protein Kaede. At 3 dpf, before ablating the β cells with MTZ from 3-4 dpf, we converted Tg(ins:Kaede)-expressing β cells from green to red by exposing them to UV light. After 2 days of regeneration (6 dpf), the surviving β cells are red and green (yellow overlap), whereas the newly formed β cells are green only.

(B and C) Confocal images of DMSO- and NECA-treated larvae with Tg(ins:Kaede)-expressing β cells at 6 dpf. Note that there is one β cell that survived the ablation in this particular DMSO-treated larva (arrow in B), whereas there are no β cells that survived the ablation in this NECA-treated larva (C).

(D) Quantification of β cell regeneration (green bars) and β cell survival (yellow bars) per larva at 6 dpf, following treatment with DMSO, NECA, Cilostamide, or A-134974 from 4-6 dpf. p < 0.0001; n = 10 larvae for each group. Error bars represent SEM. See also Figure S2.
