Figure 5. Identification and characterization of BM B-cell progenitors expressing the periostin receptor αvβ3. (A) Flow cytometry of Lin−Sca1+c-Kit+ αvβ3+ murine BM cells after 7 days of coculture with OP9 or OP9-DL cells. T-lineage cells identified with anti-CD3; B-lineage cells identified with anti-B220. (B) Flow cytometry of B-cell progenitors for αvβ3; gray histograms represent isotype controls. The data are representative of 2 experiments.
