角膜缘干细胞是角膜上皮更新的源泉，维持角膜完整性。
Corneal limbus stem cells are the source of corneal epithelial renewal and they help maintain the integrity of cornea.
采用这些标记复合体，可将角膜缘干细胞群与其他上皮细胞区分。
With these markers complex, it is easy to distinguish limbal stem cells from other epithelial cells in cornea.
结论角膜及角膜缘表层上皮较为成熟分化，而角膜缘基底细胞具有未分化细胞的特征，很可能是干细胞的部位。
ConclusionThe superficial cells of limbus and cornea are of mature status, while limbal basal cells show some undifferentiated feature, which indicates the location of stem cells.
