Cell type-specific lectin binding is a useful tool for the analysis of developing systems. We describe the binding pattern of 21 different fluorescein isothiocyanate (FITC)-labelled lectins to the testis of two model teleost species, the medaka (Oryzias latipes) and the tilapia (Oreochromis niloticus). The analysis of the binding pattern was carried out on tissue sections (medaka and tilapia) and using primary culture cells (only tilapia). Lectin binding was studied by confocal microscopy and for histological analysis some sections were, in addition, stained with bodipy to gain additional information concerning the cytological organization of the cystic mode of spermatogenesis in fish. The observed differences in lectin staining of different cell types in primary cultures were quantified by flow cytometry. Only few lectins bound specifically to haploid cells while the reaction to diploid or tetraploid cells was generally stronger. However, the extracellular material around the haploid spermatids and spermatozoa in spermatocysts showed a strong staining reaction with several lectins (e.g., Phaseolus vulgaris Erythro agglutinin). The apparent differences in the cellular lectin-binding pattern can be used to identify particular cell types, to monitor their differentiation in vitro or to enrich particular cell types from heterogeneous cultures using magnetic beads coated with anti-FITC antibodies. Using the latter approach, we show that it is possible to enrich for gonial cells and at the same time deplete the preparation for haploid cells and Sertoli cells.
