Characterization of nemaline bodies and aggregates in ACTA1-eGFPD286G muscle in zebrafish. At 2 dpf, mosaic expression of ACTA1D286G-eGFP in the muscle (green) results in the formation of nemaline bodies (arrows; i, iv, vii) that do not stain with an actinin2 antibody (red; ii and overlaid in iii), actinin3 antibody (red; v and overlaid in vi), or phalloidin (labeling F-actin, red; viii and overlaid in ix) despite correct localization of these markers in the sarcomere. At 4 dpf, mosaic expression of ACTA1D286G-eGFP results in the formation of globular aggregates (arrowheads; i, iv, vii) in the muscle (green) stain with an actinin2 antibody (red; ii and overlaid in iii), actinin3 antibody (red; v and overlaid in vi) and phalloidin (red; viii and overlaid in ix)
