    Notes: Summary The immunohistochemical localization of basic fibroblast growth factor (bFGF) was examined during wound healing in mouse skin. Frozen sections taken from the rounded skin defects were reacted with polyclonal anti-human recombinant bFGF IgG followed by incubation with FITC-conjugated IgG. The basal layer keratinocytes and hair bulbs at the wound edge were strongly stained with this antibody. In the reepithelized area, several layers of keratinocytes from the basal layer were positively stained regardless of the time after wounding. These findings suggest that germinative keratinocytes which express bFGF function as leading cells in the covering of the wound defect. However, dermal granulation tissue, including capillary endothelial cells, fibroblasts and macrophages unexpectedly did not demonstrate any immunoreactivity throughout the process of wound healing. Simultaneous histochemical investigation using cultivated mouse keratinocytes and bovine aortic endothelial cells showed primarily cytoplasmic fluorescence. The discrepancy in the staining patterns of endothelial cells in vivo and in vitro suggests that immunoreactive bFGF is either not expressed in vivo, or is processed or masked.

    Notes: The subcellular distribution of basic fibroblastic growth factor (bFGF) was analyzed by subcellular fractionation and immunofluorescence to gain insight into potential mechanisms for its release from cells. Subcellular fractionation of either SK-Hep-1 cells or NIH 3T3 cells transfected with a bFGF cDNA revealed that the 18 kd form of bFGF was found primarily in the cytosolic fraction, whereas the 22 and 24 kd forms of bFGF were found preferentially in ribosomal and nuclear fractions. Analysis of bFGF distribution by immunofluorescence using an antibody that recognized all forms of bFGF indicated both cytoplasmic and nuclear localization but failed to reveal any growth factor in structures representing secretory vesicles. Therefore, bFGF has a distribution inconsistent with that of a secretory protein.
