CHARACTERIZATION OF A NEW RAT CELL LINE ESTABLISHED FROM 2′AAF-INDUCED COMBINED HEPATOCELLULAR CHOLANGIOCELLULAR CARCINOMA
2001
A rat cell line-nominated CC-62 derived from a combined hepatocellular and cholangiocellular carcinoma obtained by administration of 2-acetylaminofluorene to male Wistar rats, has been established. Using light and electron microscopy it was determined that morphologically the tumor consisted of a mixed population of hepatocytes and cholangiolar neoplastic cells, intermingled with small, undifferentiated oval-like cells. The CC-62 line has been maintained through 90 passages in culture adopting a paving stone arrangement. Doubling time at the 12th passage was 23 h. Immunostaining with a panel of antisera was performed to identify the cytological profiles of the cell line. There was no k-ras …
Immunocytochemical typification of mesothelial cells in effusions: in vivo and in vitro models.
1994
We have performed immunocytochemical, immunoelectron microscopy, Western blot, and culture techniques using monoclonal antibodies against cytokeratin, vimentin, and desmin on 17 benign and 20 malignant effusions of pleural and ascitic origin. Triple coexpression of these three antigens was observed in benign reactive mesothelial cells as well as in one case of mesothelioma. All metastatic adenocarcinoma cells were consistently negative to desmin and positive to cytokeratin and vimentin. Present results were helpful to distinguish reactive and malignant mesothelioma from metastatic carcinoma cells in effusions.
Rabdomiosarcoma alveolar. Dos casos negativos para la fusión PAX3-FOXO1 y PAX7-FOXO1
2022
Resumen Los rabdomiosarcomas son los tumores de partes blandas mas frecuentes en la edad pediatrica y en adultos jovenes. Morfologicamente se distinguen dos subtipos principales: el rabdomiosarcoma alveolar y el rabdomiosarcoma embrionario. El subtipo alveolar se asocia generalmente con un peor pronostico y presenta una fusion genica caracteristica que clasicamente se ha utilizado para confirmar el diagnostico: PAX3/7-FOXO1. Presentamos dos casos que fueron remitidos a nuestro centro. Ambos mostraron morfologia alveolar clasica y diferenciacion muscular basada en la inmunohistoquimica; no obstante, carecian de la fusion caracteristica PAX3/7-FOXO1. El objetivo de este articulo es resaltar l…
Cytogenetic study of a spindle-cell rhabdomyosarcoma of the parotid gland.
1999
The cytogenetic analysis of a spindle-cell rhabdomyosarcoma of the parotid gland in a 6-year-old boy is reported. The tumor cells showed an abnormal karyotype with a hypotriploid modal chromosome number and clonal structural rearrangements affecting chromosomes 1, 8, 12, 21, and 22. The tumor karyotype was: 59, XY, -1, -3, -4, -5, -6, +8, +8, +del(8)(q22q24), -9, -10, del(12)(q13), -15, -16, -17, -18, der(21)t(12;21)(p11;p11), -22, der(22)t(1;22)(q12;p11).
