CD26 expression and activity in fibroblasts. (a) Flow cytometry of dermal cells. Cells were isolated from postnatal day 2 skin and stained using DAPI (live/dead marker), CD26-PerCP-Cy5.5 and PDGFRα-PE. (b) CD26 activity of confluent dermal fibroblasts treated for 5 days with IL-1α or vehicle (means±s.e.; *P<0.05). (c, d) Immunolabelling for CD26 and CD31 (c) or CD45 (d) with DAPI nuclear counterstain. Dashed lines: boundary between epidermis and dermis. Asterisk indicates hair follicle. Arrowheads in (c) indicate CD26-negative blood vessels. Arrowheads in (d) indicate co-expression of CD26 and CD45. Scale bars: 75 μm.
