Anti-trkA staining pattern of the bovine CL collected in the periovulatory period, assessed by confocal microscopy. a Grayscale intensity values of immuno-reactive cells and (b) number of immuno-positive cells per high-powered field (mean ± SEM) in the CL among different day-groups (n = 3–5 ovaries per group; Day 0 = ovulation). c-f Photomicrographs depicting anti-trkA immuno-fluorescence (green) in bovine CL on Day 2 (c), Day 4 (d), Day 6 (e) and Post-LH (f). Cell nuclei are shown in red (pseudo-color). Scale = 20 μm
