Figure 1. Human mammary epithelial cells and BCCs with ectopic expression of POSTN exhibit stem-like cell properties.

Figure 1

A. Generation of stable cell lines that constitutively expressed either POSTN or empty vectors. B, C. Mammosphere formation from MCF-10A/Vector, MCF-10A/POSTN, MCF-7/Vector, and MCF-7/POSTN cells. The data are the means ± SD. **P<0.01. D, E. The frequency of CD44high/CD24low stem-like cells in MCF-10A/Vector, MCF-10A/POSTN, MCF-7/Vector, and MCF-7/POSTN cells. The percentages of CD44high/CD24low cells are shown as means ± SD.
