• tumor cells
  • It is therefore often desirable to grow tumor cells in the organ from which they originated. (jove.com)
  • The issue of monoclonal versus oligoclonal origin of multifocal urothelial carcinomas is clinically important because an understanding of patterns of early tumor development must be considered in the development of appropriate treatment and surgical strategies and in the genetic detection of recurrent or residual tumor cells in posttreatment urine samples ( 6 - 10 ).

  • bladder tumor
  • These results suggest that let-7c downregulation and its regulated cell-cycle pathway may play an integral role in governing bladder tumor suppression or collaborative oncogenesis and that Iressa exhibits its preventive efficacy on bladder tumorigenesis by upregulating let-7 and inhibiting the cell cycle. (aacrjournals.org)
  • Cell culture study confirmed that the increased expression of let-7c decreases Iressa-treated bladder tumor cell growth. (aacrjournals.org)
  • epithelial cells
  • Early changes include disorganization of the epithelial cells, with the superficial cells becoming oriented horizontally with respect to the basal lamina. (nih.gov)
  • metastatic
  • Metastasis means that cells spread through the tissue fluid's circulation called the lymphatic system or through the bloodstream where they can then stop off in other tissues or organs where they may grow as metastases or metastatic deposits and can become destructive in these new locations.

  • atypia
  • If features of atypia are present, it should be should be diagnosed by adding the modifier, "atypical. (nih.gov)
  • grade
  • At termination, interferon gamma (IFN-γ)/interleukin-4 (IL-4) ELISpot analysis for MUC1 specific T-cell immune response and histopathological evaluations of tumor type and grade were performed. (jove.com)
  • typically
  • This lesion must be differentiated from regeneration, which is typically 1 or 2 cell layers thick. (nih.gov)
  • tissues
  • Embodiments of the present invention are directed to quantitative analysis of tissues enabling the measurement of objects and parameters of objects found in images of tissues including perimeter, area, and other metrics of such objects. (google.com)
  • layer
  • Successful tumor cell implantation in this model requires disruption of the protective glycosaminoglycan layer, which can be accomplished by physical or chemical means. (jove.com)
