Plexin-B1 expression in normal microenvironmental cells.

RT-PCR analysis of Plexin-B1 expression in 2 samples of normal primary BM stromal cells, in a follicular dendritic cell line (FDC-1), in normal in vitro–activated T lymphocytes, in macrophages, and in monocyte-derived dendritic cells (DCs). The size of Plexin-B1–amplified products was 303 base pairs as expected.
