Vimentin expression was required for proper wound healing.

(A) Morpholino knockdown (MO1) of vimentin caused a significant wound healing defect in (B) regenerate area at 3 dpw (p<0.0001; n = 85 total larvae per treatment over four replicates, with 17 to 30 larvae per treatment per replicate; Ctl MO 95% CI = 94604.23 to 101336.98; vim MO 95% CI = 60550.63 to 67369.68). (C) Schematic of single-site CRISPR-Cas9 targeting of vimentin (top). Arrowhead indicates the presence of aberrant banding in the mosaic F0 mutant (bottom). Sequencing of the vim guide RNA target sites was also performed (see Materials and methods) on single embryos to further validate. (D) One example of sequencing results shows a 7 bp deletion in Exon 1, an early stop codon. (E) Amino acid alignment of vimentin from germline genomic DNA from adult F0 mosaic adults. (F) Mosaic F0 mutant larvae (Vim) displayed a significant defect in (G) regenerate area at 3 dpw (p<0.0001; ctl n = 130 larvae total, Vim n = 119 larvae total over 3 replicates with 36 to 45 larvae per treatment per replicate; ctrl 95% CI = 110643.20 to 115689.47, Vim 95% CI = 90275.48 to 95555.25). Scale bars in A and F represent 100 µm. Statistical significance: ****p<0.0001, error bars are standard deviation.
