Acidic and basic fibroblast growth factors (aFGF and bFGF), are both known to bind to extracellular matrix components, particularly proteoheparin sulfates, and to regulate in vitro proliferation, differentiation and morphology of cells of neuroectodermal and mesodermal origins. Their patterns of distribution were studied during mouse odontogenesis by means of indirect immunofluorescence and immunoperoxidase histochemistry on frozen fixed sections and after Bouin's fixative and paraffin embedding. Localization of aFGF on frozen fixed sections was observed in the oral epithelium, dental lamina and oral mesenchyme (day-12 of gestation), the stellate reticulum and oral epithelium (day-14), the stratum intermedium and at the basal and apical poles of preameloblasts at bell stage. After birth aFGF epitopes were localized within the predentin-dentin area, the stratum intermedium and at the secretory pole of ameloblasts. There was no staining with anti-aFGF antibodies after Bouin's fixative and paraffin embedding. In contrast, using this protocol, intense stainings were found with anti-bFGF antibodies predominantly within dental and peridental basement membranes and mesenchyme: staining of the dental basement membranes was transient (bud and cap stage) and discontinuous; a preferential concentration of bFGF epitopes in the condensed dental mesenchyme of incisors (cap stage) and the dental papillae mesenchymal cells of molars (bell stage) was observed in the posterior and the cervical part of tooth germs. An intense immunostaining of the stellate reticulum with anti-bFGF antibodies was also found on paraffin sections from bud to bell stage.(ABSTRACT TRUNCATED AT 250 WORDS)
