无结构的

Samples of the composites were taken for histological examination at day 7 and day 14 since OKCs were seeded. Results Multi-layer epithelia without hemidesmosome and basal membrane were observed in composites of PGA showing ill-defined cell layers. OKCs could adhere and proliferate onto collagen membrane forming multi-layer epithelia, with no mature hemidesmosome and basal membrane. That of Alloderm showed normal epithelial structures, with hemidesmosome, basal membrane and cell pseudopod in lamina propria.

结果 以PGA为支架构建的组织工程化口腔黏膜，含类似上皮层和固有层，但细胞层次不清；胶原膜上可见口腔黏膜上皮细胞黏附生长，并形成复层上皮样组织，但无成熟的桥粒及基底膜样结构；以Alloderm作为支架材料的构建物，出现正常上皮形态，含半桥粒及细胞指状突起等超微结构。
