Expression of markers on fibrocytes, fibroblasts, and endothelial cells.

PBMC were cultured as described in Figure 1. Normal human dermal fibroblasts and HUVECs were cultured for 2 days in 8-well glass slides. Cells were then air-dried, fixed, and stained with antibodies against A–C) CD43, D–F) CD44, G–I) CD45, J–L) LSP-1, and M–O) CD29. Cells were then counterstained with hematoxylin to identify nuclei. Bar is 50 µm.
