The ultrastructure of fetal and adult bovine epithelial-mesenchymal interface of the ruminal mucosa was described and then correlated to the biochemical analysis for glycosaminoglycans (GAGs). During development a progressive undulation of the basement membrane, increase of connective tissue filamentous material, and folding of the cellular membrane of the basal epithelial cells were observed. Coincidently, a decrease in the relative composition of hyaluronic acid and an increase in chondroitin sulfate was observed. These results suggest a correlation between glycosaminoglycans composition and the expression of some cellular events resulting in morphological changes which operate during ruminal morphogenesis.
描述了胎儿和成年牛瘤胃黏膜上皮-间充质界面的超微结构，然后将其与糖胺聚糖（GAGs）的生化分析相关联。在发育过程中，观察到基底膜逐渐起伏、结缔组织丝状物质增加以及基底上皮细胞细胞膜折叠。同时，观察到透明质酸的相对组成减少，硫酸软骨素增加。这些结果表明糖胺聚糖组成与瘤胃形态发生过程中导致形态变化的一些细胞事件的表达之间存在相关性。
