About 4 days post amputation, cells in some areas in the out epidermis and inner parietal peritoneum near the end of the stump are induced by injury to dedifferentiate into stem cells and then proliferate forming stem-cell masses, which then invaginate into the interior dermis. The dermal cells are then induced by those invaginating stem-cell masses to dedifferentiate.

The morphology and structure of reconstructed tissue was detected by microscope and scanning electron microscope.Results:(1) Compared with the control group, the cellular proportion of laminin group increased in 62 ~M phase, and decreased in Go~Gi phase significantly. As shown by the microscope, the cells of control group were in low density. The cells in mass connected tightly. The microfilament appeared reticular formation. The nucleus were the same in size. The cells of laminin group were in high density and put out so many lamellipodia, filopodia, which connected with the surrounding cells. The microfilament increased, elongated, and changed from reticulodromous to sarciniform, which reached to the pseudopods. The nucleus were different in size .(2) As shown by the inverted microscope and the cell growth curve, comparing with the controlgroup, cells of each test group increased evidently. The cellular proportion of each test group increased in S phase and G2 ~M phase, and decreased in Go~Gi phase significantly, but there was no considerable interations between LN and EGF;(3) As shown by the morphological observations, the cultured cat corneal endothelial cells formed an integrated membrane, and attached to the Descemets membrane closely, which was similar to the natural tissue. The cells connected tightly to each other, and some of them arranged in hexagon approximately.

结果：(1)层粘连蛋白组处于G_2～M期细胞比例较对照组显著提高，Go～G_1期细胞比例显著下降，提示层粘连蛋白促进内皮细胞DNA合成，及细胞分裂增殖；光镜下，对照组细胞分布成团状，细胞密度较低，细胞间连接紧密，细胞内微丝结成网状，细胞核大小一致；与对照组相比，层粘连蛋白组细胞生长旺盛，细胞密度高，向周边伸出大量板状及丝状伪足，细胞内微丝增多、拉长、集结成束，伸入伪足中，细胞核形状大小不一致；(2)倒置显微镜观察及细胞生长曲线显示，各组细胞数目随时间增加而明显增多，各实验组较对照组增生显著，EGF和LN联合应用组各时间点细胞数目最高；实验组处于S期和G_2～M期细胞数目增加，Go～G_1期细胞数目减少；提示EGF、LN单独及联合应用均可促进细胞增殖，但尚不能认为二者有交互作用；(3)倒置显微镜下，组织培养的猫角膜内皮细胞排列成密集的单层，细胞间连接紧密；组织学观察发现，培养的猫角膜内皮细胞形成完整的内皮层，贴附于脱水基质的后弹力膜上，与正常的角膜内皮组织结构相似；扫描电镜下，组织培养的猫角膜内皮细胞间紧密镶嵌排列，可见某些细胞呈近似六边形排列，细胞大小不甚一致，胞核清晰。
