CDNR4 Cells

The CDNR4 cell line comprises a specialized subset originating from the COMMA-D cell line, known for modeling mouse mammary carcinoma. This clonal subpopulation has undergone extensive characterization, revealing a range of unique properties and functionalities. One of the most striking features of CDNR4 cells is their resemblance to mammary stem cells, which positions them as a significant resource for exploring aspects of stem cell biology, carcinogenesis, and cellular heterogeneity within populations. These cells were developed through the transfection of a transposon bearing kanamycin and neomycin resistance genes (Tn5 gene), which led to the emergence of various intriguing traits and capabilities, including their potential to differentiate into both preneoplastic and neoplastic phenotypes. Originating from the COMMA-D line, which was initially studied for its cellular heterogeneity using a variety of techniques such as phase contrast microscopy, immunocytochemical staining, DNA content analysis, and evaluations of oncogenic potential, CDNR4 stands out as a distinct clone. Through specific transfection and selection methods, clonal subpopulations like CDNR4 were isolated, each maintaining a degree of the heterogeneity seen in the original COMMA-D parental cells. This retention of heterogeneity underscores the complex nature of these cell populations and enhances the value of CDNR4 cells in research focused on cellular differentiation and cancer progression.
