Última Nestin-positive Stem Cells Participate in Chondrocyte Renewal in Healthy Adult Lung Cartilage International Journal of Morphology Ortega-Martínez,Marta; de-la-Garza-González,Carlos; Ancer-Rodríguez,Jesús; Jaramillo-Rangel,Gilberto. It is considered that healthy adult cartilage has little or no capacity for renewal, and that chondrocytes maintain a stable resting phenotype and resist proliferation and differentiation throughout life. Recently we found that cell turnover in lung cartilage is possible and that nestin-positive cells may have a role in it. In this paper, we report additional findings about chondrocyte renewal in lung cartilage. Lung specimens from CD1 mice at the age of 2, 6, 12, 18 or 24 months were fixed in 10% neutral-buffered formalin and paraffin-embedded. Nestin expression was examined by an immunohistochemical peroxidase-based method. We found nestin-positive cells inside of cartilage islets and cells in division very close from them. Our findings indicate that... Tipo: Journal article Palavras-chave: Cartilage; Chondrocyte renewal; Nestin; Stem cells.

García-Labastida,Laura; Garza-Guajardo,Raquel; Barboza-Quintana,Oralia; Rodríguez-Sanchez,Irám Pablo; Ancer-Rodríguez,Jesús; Flores-Gutierrez,Juan Pablo; Gómez-Macías,Gabriela Sofía. BACKGROUND: Pure mucinous adenocarcinoma of the breast is a rare entity characterized by the production of variable amounts of mucin comprising 1% to 6% of breast carcinomas. Some mucinous adenocarcinomas have shown expression of intestinal differentiation markers such as MUC-2. This study examines the expression of intestinal differentiation markers in this type of breast carcinoma. RESULTS: Twenty-two cases of pure mucinous adenocarcinoma of the breast were assessed. Immunochemistry was performed for beta-catenin, CDX-2 and MUC-2. All cases were positive for B-catenin. MUC-2 positivity was observed in all cases; 63. 6% were 3 plus positive. All cases were negative for CDX-2. CONCLUSIONS: These results suggest that mucinous breast carcinomas express some...
