Análise imuno-histoquímica das citoqueratinas em ameloblastoma e tumor odontogênico adenomatóide

Abstract

Objectives: The aim of the present study was to describe the immunohistochemical expression of cytokeratins (CKs) 7, 8, 10,13, 14, 18 and 19 in the epithelial components of ameloblastomas and adenomatoid odontogenic tumor (AOT). The results were compared and histogenesis discussed. Material end method: Specimens of ten ameloblastomas and eight adenomatoid odontogenic tumors were examined by immunohistochemistry using streptavidin-biotin-peroxidase complex method and anti-CKs antibody. The sample was obtained from

Increased expression of matrix metalloproteinases 2 and 9 as poor prognosis factor for Hodgkin's lymphoma patients

“…All 10% formalin-fixed, paraffin-embedded HL specimens from the cases selected for this study were submitted to 4µm histological sections placed on silanized glass slides for immunohistochemistry (IHC), following the protocol proposed by Lopes et al 18 and Pedroso et al, 19 with minor modifications according to the standards of the Laboratory of Cytological and Molecular Research of the Federal University of Pernambuco, Brazil.…”
