| Outline of Final Research Achievements |
The precise role of fibrocytes in angiogenesis in wound healing remains unclear. Our aim is to clarify the role of fibrocytes in angiogenesis influenced by basic fibroblast growth factor (bFGF) in wounds. Double immunofluorescence staining focusing on fibrocyte accumulation demonstrated markedly increased formation of capillary-like structures composed of CD34+/pro-collagen I+ fibrocytes in bFGF-treated wounds. However, capillary-like structures formed by CD45+/pro-collagen I+ or CD11b+/pro-collagen I+ fibrocytes were lacking in these wounds. Furthermore, bFGFR1-small interfering RNA (siRNA) injection into wounds followed by bFGF treatment markedly inhibited the formation of capillary-like structures composed of CD34+/pro-collagen I+ fibrocytes, indicating the requirement of bFGF for formation of the capillary-like structures composed of CD34+/pro-collagen I+ fibrocytes in the wounds.
