EPH/EPHRIN signaling affects tissue morphology.
(A) In the left panels, representative images show that EPHB2-GFP (green) cells mixed with EPHB2-GFP-LifeAct-mCherry (magenta) cells in hanging drop cultures for 72 h form circular aggregates. In the right panels, EPHB2-GFP-LifeAct-mCherry (green) cells mixed with EPHRIN-B1-LifeAct-mCherry (magenta) cells in hanging drop cultures for 72 h segregate and form highly tortuous aggregates. Scale bar, 100 µm. (B) HEK293 cell–isolated aggregates formed in hanging drop cultures 72 h after mixing. Morphology changes observed in segregated aggregates are disrupted by inhibition of ROCK and MLCK with Y27632 and ML7. Scale bars, 50 µm.
