Lectin binding histochemistry was used to investigate the glycoconjugate saccharidic moieties in the respiratory epithelium of human fetuses ranging in age from the 8th to the 12th week of gestation. The distribution and changes in the sugar residues of the glycoconjugates at the level of the basal cells, the bathyprismatic cells and the bathyprismatic ciliated cells are reported. PNA and SBA allowed the identification of some 'elongated cells', which were characterized by lectin-reactive supranuclear granules. These epithelial cells, which have not previously been identified using conventional histochemical methods, might be the precursors of secretory cells.
采用凝集素结合组织化学方法，研究了妊娠8至12周人胎儿呼吸道上皮中的糖缀合物糖部分。报告了糖缀合物糖残基在基底细胞、深柱状细胞和深柱状纤毛细胞水平上的分布及变化。花生凝集素（PNA）和大豆凝集素（SBA）可识别一些“伸长细胞”，其特征为具有凝集素反应性的核上颗粒。这些上皮细胞以前用传统组织化学方法未被识别，可能是分泌细胞的前体。
