Both epidermal growth factor (EGF) and transforming growth factor (TGF) play an important physiological role in the processes of proliferation and differentiation of several different cell types. However, the expression profiles of these factors in domestic bitches endometrium are still poorly recognized. The aim of the present study was to identify and analyze the differential expression of these...
Several years ago, the presence of macrophages in the tumor microenvironment was thought to be an inflammatory response to kill the cancer cells. Now, this is clear that the inflammatory cells that exit blood vessels and migrate to the tumor tissue play an important role in cancer progression. Various cells present in the tumor microenvironment enhance cancer growth and invasiveness by secretion of...
Nineteen canine lymphomas were included in this study. Tumors were classified according to the updated Kiel classification adapted for canine lymphomas by Fournel-Fleury et al. Immunoglobulin light chains (κ and λ) and IgM and IgG expression were determined by immunohistochemical method. In all examined cases neoplastic cells were positive for one of the immunoglobulin light chains. Expression of...
Using imunohistochemical technique, localisation and intensity of COX2 expression were estimated in canine soft tissue fibrosarcomas. The obtained results were related to tumour grade of malignancy. The material was sampled in the course of surgery from 23 dogs of various breed, 5 to 18 years of age. The presence of COX2 was demonstrated in cell cytoplasm in over 43% tumours. Augmented expression...
