  • Histological and immunohistochemical investigation of canine prostate carcinoma with identification of common intraductal carcinoma component
    'Wiley', 2021
    Co-Authors: Brot Simone, Lothion‐roy Jennifer, Grau‐roma Llorenç, White Emily, Guscetti Franco, Rubin, Mark A., Mongan, Nigel P.
    Abstract:

    A limited number of species, including men and dogs, spontaneously develop prostate cancer (PC). The histological and molecular relevance of canine PC as a model for the disease in men remains controversial. To address this challenge, this study aimed to assess the histomorphology and expression of basal cell, urothelial and neuroendocrine markers [p63, high molecular weight cytokeratin (HMWCK), Uroplakin 3 (UPIII), neuron-specific enolase (NSE)] in canine PC (n = 41). Based on histomorphology, 10/41 (24%), 21/41 (51%) and 9/41 (22%) were classified as adenocarcinoma (AC), urothelial carcinoma (UC), and mixed carcinoma, respectively. Tumour inflammation was common, frequently severe [20/41 (49%)], and associated with neutering (p

Tumour inflammation was common, frequently severe [20/41 (49%)], and associated with neutering (p < .02) and urothelial differentiation (p < .02). Most (36/40, 90%) cancers contained only rare cells with basal cell marker expression or were negative. The expression of UPIII was absent or weak in the majority (33/38, 87%) of tumours, with moderate to strong staining in the remaining cases. NSE expression in PC was rare and limited to 2/14 (14%) cases. Tumour extension into benign ducts and glands was a common finding with presence in 17/39 (44%) of carcinomas with and without urothelial differentiation. In conclusion, we confirm that canine PC is characterized by absent or weak expression of basal cell and urothelial markers. Although rare, NSE expression, potentially indicating neuroendocrine differentiation, is reported for the first time in canine PCa. Intraductal carcinoma of the prostate with concurrent invasive PCa (IDCP-inv) is a frequent, not previously described, finding in dogs with PC

    2014
    Co-Authors: Hans M. Larsson, Francois Gorostidi, Jeffrey A. Hubbell, Yann Barrandon, Peter Frey
    Abstract:

    (A, B and C) Porcine urethelial holoclone, meroclone and paraclone cultures arising from a single urethral cell. (D and E) Growth curves of a porcine urothelial holoclone. (F, G) In vivo urothelial differentiation of porcine urethral urothelial holoclonal cell pellets implanted into the subcapsular space of the Swiss nu/nu mice, expressing cytokeratin 7, Uroplakin-2 and Uroplakin 3 (scale bars, 10 µm). Note the “micro-bladder” like structure.

    Abstract:

    (A) Schematics showing the passage from the single selected cell to the in vivo implantated clonal cell pellet. (B,C and D) Human urothelial holoclone, meroclone and paraclone cultures arising from one single ureteral cell. (E and F) Growth curve of a human urothelial holoclone (G) In vivo urothelial differentiation of human ureteral urothelial holoclone pellets implanted into the subcapsular space of the Swiss nu/nu mice, expressing cytokeratin 7, Uroplakin-2 and Uroplakin 3 (scale bars, 10 µm).

  • Urothelial cell differentiation and “micro-bladder” formation in mice.
    2014
    Co-Authors: Hans M. Larsson, Francois Gorostidi, Jeffrey A. Hubbell, Yann Barrandon, Peter Frey
    Abstract:

    (A and B) Hematoxylin & eosin (H&E) staining of an implanted mass-cultured, native porcine bladder urothelial cell pellet into the subcapsular space of a Swiss nu/nu mice kidney (A: scale bar 500 µm, B: scale bar 50 µm, urothelial bundle-like structure indicated with black star and epithelial “micro-bladder” like structure indicated with red star). (C–H) Immunohistochemistry of the implanted urothelial pellet forming urothelial bundle-like structures (C, E and G) and “micro-bladder” like structures (D, F and H) using antibodies against Uroplakin-2 (C and D), Uroplakin-3 (E and F) and Ki-67 (G and H) (scale bars, 10 µm).
