摘要: 目的 通过研究灌流眼前节培养和组织块培养的小梁细胞的差异,了解这两种原位培养法在青光眼研究中的应用。方法 采用灌流眼前节培养和原位组织块培养法对猪眼小梁细胞进行培养,用光学显微镜观察不同培养方法保存的小梁细胞和小梁网的状态。结果 恒速(0.1ml/h)灌流猪眼前节,眼压可以稳定在正常眼压范围(10~12mmHg),灌流成功率为50%;在一定范围内,随着流量增加眼压能逐步升高。灌流培养的器官大体形态保留完好,组织层次清晰,细胞状态好。组织块原位培养的小梁组织,周边组织结构保留完好,细胞状态尚可,但是小梁网间隙不如灌流培养的小梁网间隙饱满。结论 灌流眼前节培养法更接近生理状态,小梁网的正常充盈是维持其功能和机构的必要条件

Abstract: Objective To study the differences of trabecular meshwork cells cultured by perfused anterior segment and tissue sheet culture method, and to clarify their application in glaucoma study. Methods Trabecular meshwork cells were cultured by perfused anterior segment and tissue sheet culture method, light microscope was used to observe the trabecular meshwork cells and intercellular spaces. Results IOP of the porcine anterior segments perfused under constant rate at 0.1ml/h could maintain in the normal range(10~12mmHg). The success rate was 50%. The IOP could be elevated with the increasing of perfusion rate, while the shape and structure of the organ were well preserved. Trabecular meshwork cultured by tissue sheet culture method could also reserve the tissues well, but the intercelluar spaces collapsed . Conclusion Perfused anterior segment could better simulate the normal physical state in situ and adequate perfusion was necessary for normal trabecular meshwork.
