Acute promyelocytic leukemia (APL) is an acute myeloid leukemia characterized by leukemic cells blocked at the promyelocytic stage of granulocytic differentiation. According to the FrenchAmerican-British (FAB) classification, two main cytological subtypes are recognized: (i) classical hypergranular promyelocytic leukemia (M3) and (ii) the microgranular promyelocytic leukemia variant (M3v). Rece...
The human Lin2CD342 cell population contains a newly defined class of hematopoietic stem cells that reconstitute hematopoiesis in xenogeneic transplantation systems. We therefore developed a culture condition in which these cells were maintained and then acquired CD34 expression and the ability to produce colony-forming cells (CFC) and SCIDrepopulating cells (SRCs). A murine bone marrow stromal...

introduction: solitary fibrous tumours (sfts) of the nose and paranasal sinuses are extremely rare.these were originally described as neoplasms of the pleura originating from spindle cells. it is further sub-classified as a benign type of mesothelial tumour. its occurrence in many extra pleural sites have been reported earlier, mainly in the liver, parapharyngeal space, sublingual glands, tongu...
Aims: Strong expression of CD 34 has been described in many tumors. It has been proposed that these lesions arise from long-lived mesenchymal cells. We tested the hypothesis that spindle cell lesions of the breast arise from similar mesenchymal cells in mammary stroma, and to determine the potential diagnostic value of CD 34 immunostaining in these lesions. Methods and results: Sections of fibr...
OBJECTIVE 1. To evaluate the percentage of caspase-3 and CD-34 expression on adenocarcinoma; 2. to quantify caspase-3 and CD-34 in tumor cells; 3. to verify the relationship between biomarkers and its malignancy; 4. to correlate biomarkers themselves. METHODS Thirty-eight human malignant prostate specimens, Gleason's score, were immunohistochemically stained for caspase-3 and CD-34 protein. Q...
