Fig. 3. Phenotypic characterization of PZP cells.

a PZP cell lines were stained with CD105 and CD26 antibodies to identify the lobular and interlobular origin of PZP cells (n = 3). Isotype controls are shown in Fig. S2a and e. b and c Quantification of CD105^high/CD26^– and CD105^high/CD26^low population of cells (n = 3). d PZP cell lines were stained with CD90 and CD73 antibodies to identify rare endogenous pluripotent somatic stem cells and potential mesenchymal stem cells (n = 3). Isotype controls are shown in Fig. S2. e–g Quantification of CD90^–−/CD73^high, CD90^low/CD73^high, and CD90^high/CD73^high population of cells (n = 3). h PZP cell lines were stained with CD44 and CD24 antibodies to determine whether their phenotype overlaps with cancer stem cells (n = 3). Isotype controls are shown in Fig. S2. i Quantification of CD44^high/CD24^low population (n = 3). j PZP cell lines were stained with CD10 antibody to determine overlap with myoepithelial cell marker expression (n = 3). k Quantification of CD10⁺ population (n = 3). All the data points are shown as mean ± SEM. Source data are provided as a Source Data file.
