Klf2 functions cell non-autonomously to maintain the integrity of the myocardial wall.

(A) Schematic representation of the experiment shown in (B–E). (B–E) Transplantation of Tg(myl7:MKATE-CAAX); klf2^+/+ donor cells into Tg(myl7:LIFEACT-GFP); klf2^+/? (B and D) or klf2^-/- (C and E) hosts shown at 96 hpf; white arrows point to klf2^-/- extruding cardiomyocytes in klf2^-/- heart, orange arrows point to klf2^+/+ extruding cardiomyocytes in klf2^-/- hearts; maximum intensity projections of confocal z-stacks of hearts in (B) and (C) are shown in (D) and (E), respectively. (F) Schematic representation of the experiment shown in (G-J). (G–J) Transplantation of Tg(myl7:LIFEACT-GFP); klf2^+/? (G and I) or klf2^-/- (H and J) donor cells into Tg(myl7:MKATE-CAAX); klf2^+/+ hosts shown at 96 hpf; maximum intensity projections of confocal z-stacks of hearts in (G) and (H) are shown in (I) and (J), respectively. V: ventricle, At: atrium; scale bars, 50 µm.
