Whilst confocal microscopy of the cord/abscess-containing environments demonstrated massive mobilization of neutrophils around cords (Fig 6E and S2 Movie) and abscesses (Fig 6F and S4 Movie) in WT embryos, this was not true in tnfr morphants (Fig 6E and S3 Movie, Fig 6F and S5 Movie). The gene discussed is TNFRSF1A; the disease is abscess.
