It is well known that retinal pigment epithelial cells are predominant proliferative cells in PVR which is an excessively wound healing response occurring after RPE cell wounding. The activated RPE cells migrate from their normal, sessile state to vitreous and onto both surfaces of the retina, in which they begin to dedifferentiate, migrate, proliferate, change phenotype and secrete ECM.

既往研究证明视网膜色素上皮(retinal pigmentepithelial，RPE)细胞是参与PVR的主要细胞，PVR是视网膜脱离后RPE细胞损伤的一种自我修复过程，是一种过度的眼内创伤修复反应；RPE细胞在正常位置上处于静止状态，而在某些病理条件下，如视网膜裂孔形成和视网膜脱离后，RPE细胞脱离原位，开始去分化、移行、增生、发生表型转化并分泌胶原等ECM，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。

The barley chromosome in wheat was identified by genomic in situ hybridization in which biotin labelled total genomic DNA of barley betzes was used as probe and the unlabelled total DNA of common wheat Chinese Spring as blocking DNA. A series of wheat materials were tested as follows; two disomic alien substitution and monosomic alien addition lines, 2n=43; two monosomic alien substitution lines.

用生物素(Biotin-16-dUTP)标记的大麦Betzes基因组DNA作探针，以普通小麦中国春总DNA作封阻进行基因组原位杂交(Genome in situ hybridiz ation，简称GISH)，从13株小麦-大麦杂交后代中鉴定出2个含有3条大麦B etzes2H染色体的材料(2n=43)；2个2H单体异代换系(2n=42)；7个2H二体异代换系(2n=42)。

Orientale additional and substitutional lines. chromosome number of 96 BC2 F3 individuals were accounted. Fifteen plants with 2n= 43 and eight plants with 2n= 44 were checked out. GISH results of the individuals with 43 chromosomes showed that they blonged to three different monosomic additions. Two disomic additions, ine double-monosomic addition, one trible- monosomic addition and one monosomic addition were found in the 2n = 44 individuals. One double-monosomic substitution and one monosomic sustitution were obtained.
