The slow progress of researches on pulmonary stem cells up to date has its root in the complex structure of pulmonary tissues and respiratory tracts, which is demonstrated by the facts that the respiratory system is composed of at least 40 types of cells, plus that the growth, renewal, and regeneration rate or capacity of respiratory epithelium are extremely limited. Mean while, there have been no specific stem cell markers for pulmonary and lung cancer, so researchers rely on stem cell markers borrowed from other systems to search for stem cells in pulmonary system.

目前对于肺干细胞的研究进展缓慢，究其原因主要是肺组织和气道具有复杂的内在结构，呼吸系统至少包含40种不同类型的细胞，呼吸上皮本身只有极低的生长更新率和非常有限的再生能力，同时肺干细胞的表面标志物也缺乏特异性，只能借助其他组织已知的干细胞标记物进行对比观察。

The animal models with limbal stem cell dysfunction were made by limbus region resection combined with curettement of the corneal epithelium.

以新西兰白兔为实验对象，采用角膜缘切除联合角膜上皮刮除的方法制作兔角膜缘干细胞缺乏的模型。

The animal experiment stage: 40 rabbits underwent corneal epithelium curettement and limbal ablation to induce limbal stem cell deficiency and were randomly divided into four groups, simple amniotic membrane group, non-frozen cells group, glycerol group and dimethyl sulfoxide group(n=10 for each group). Searching for the activity of frozen and non-frozen cells more completely by transplanting subculturing cells and observing the accomplishment of cells function.

动物实验阶段：将40只角膜缘干细胞损伤的模型兔随机分成单纯羊膜组、未冷冻细胞组、DMSO保存细胞组和甘油保存细胞组，每组10只，用传代培养2周后的角膜缘上皮细胞作移植实验，观察细胞体外功能完成情况来进一步比较深低温保存前后角膜缘上皮细胞的活性。

On day 7, a low level of COX-1 immunostaining was seen in the luminal epithelium and primary decidua.

Results Punctiform erosion, hemorrhage were observed by nake eyes in each groups. Epithelium cellular necrosis, defluxion, neutrophil being dominant in propria lamina and intact glandular were observed with microscopy. The erosion became severe with the successive stimulate of ethanol. There is no difference between distillate spirit and sodium chloride rats in Guth in 7th day, but Guth in distillate spirit rats was higher than that in sodium chloride rats in 30th day. PGE2, TGF-α contents in gastric mucosa of treated group increased significangly compared with control group. PGE2 showed no difference between each group in 7th and 30th day; TGF-α in gastric mucosa of distillate spirit and sodium chloride rats decreased after 1 month.
