From: Heat shock protein expression in canine malignant mammary tumours
HSP immunohistochemical expression in normal canine mammary gland tissue. (a) Hsp27 expression absent; (b) focal Hsp72 expression in both the cytoplasm and nucleus of single epithelial cells and isolated alveolar structures; (c) strong and diffuse Hsp73 immunolabelling; (d) moderately intense and diffuse Hsp90 immunostaining in lobular cells. Scale bar 20 μm.
