Figure 3. Skin and tissue repair after cutaneous injury.

Figure 3.

(a-b) Magnified stereoscope images of the flank of the same fish (a) or representative Masson Trichrome transverse cross sections (b) of fish epidermis, scales, fat and muscle in uninjured tissue, after injury tissue, or 2 days post injury (dpi) tissue. (c-d) Magnified stereoscope images of the flank of the same fish (c) or representative Masson Trichrome transverse cross sections (d) of cutaneous injury tissue in intervals from 4dpi to 20dpi. (e) Maximum projection confocal images of XY (top view) and XZ (side view) planes of adult Tg(krt4:lyneGFP)sq18 transgenic fish with keratinocytes in green, showing skin re-epithelialization occurs within the first 24 hours after wounding. Images are oriented anterior left and dorsal up, except for Masson Trichrome images which are oriented dorsal left and lateral up. Scale bars = 2000μm (a,c), 100μm (b,d), 1000μm (e).
