The pattern of aerenchyma formation could originate by the combination of cortical cell autolysis and enlarged intercellular space. The process occurred in some stages: cortical cells stopped expansion and the intercellular space became larger at the initial stage. Cortical cells to collapse and autolysis were found with the disintegration of cell contents. After the evacuation of cell contents, cortical cells became shrinking and invaginated.

形成过程大体分为：皮层细胞生长停止，细胞间隙增大；皮层细胞衰老，并发生自溶，内含物解体；解体物逐渐撤走，皮层细胞开始收缩、内陷，当细胞内含物全部撤走，相邻细胞的残留细胞壁叠合即在两侧形成通气空腔；径向上相邻的皮层细胞逐步发生凹陷和细胞壁叠合，结合方形的细胞间隙一起构成通气组织。

The histopathologic changes included lymphocyte and monocyte infiltration,hyperplasia of synovial cells and small vessels,interstitial fibrosis,hyaline degeneration and cartilaginous metaplasia.The immunohistochemical observations showed that the high expressions of IL-1 and IL-6 were significantly different between the pathologic plicae and the control groups（P＜0.01）.The positive expressions of IL-1 and IL-6 were the synovial cells and monocyt-lymph cells in the pathologic synovial plicae.The positive expressions of MMP-1 and TIMP-1 have significant difference between the experiment and control group（P＜0.01,P＜0.05）.The expression of MMP-1 was positive in synovial lining cell,monocyte,fibroblast,endothelial cell in small vessel and chondrocyte.The TIMP-1 expression was detected in the synovial lining cells and a small quantity fibroblast.

BMSCs were isolated, depurated, cultivanted, and identified,then incubated with the concentration of 25μg Fe per milliliter at 37℃in 5% CO2. The labeled cells were stained by Prussian blue/trypan blue,and observed under fluorescent microscope.2. The labeled cells of different density (1×104/ml,5×104/ml,1×105/ml,5×105/ml,1×106 /ml,5×106/ml)were imaged by MRI with T1WI, T2WI and T2*WI sequences;and the same density (5×104/ml,1×105/ml)labeled cells were imaged by T2*WI sequences at different time.Then the signal intensities were measured and statistically analyzed.3. The model of rabbit renal ischemia-reperfusion injury was set up and treated. Then BMSCs(5×105)were injected into 16 recipient rabbits(1abeled cells in 10,unlabeled cells in 6)from ear vein.MR images of kidneys were obtained respectively at the time points of 0,1,3,5, 8 days after transplantation and before transplantation. MR imaging findings were analyzed,which were correlated with histological findings.
