大鼠骨髓單核細(xì)胞移植對(duì)潰瘍性結(jié)腸炎模型大鼠的修復(fù)作用
[Abstract]:Objective to investigate the effect of bone marrow monocyte (BM-MNCs) transplantation on (UC) repair in ulcerative colitis. Methods the labeled allogeneic BM-MNCs was transplanted into the rat UC model to observe the changes of spirit, food intake, activity, defecation and body weight, colonic gross morphology and mucosal tissue injury in rats. Results the general condition, body weight and defecation of the rats 7 days after transplantation were significantly better than those of the phosphate buffer (PBS) group, and the colonic tissues of the rats were observed under light microscope. There was no significant difference between the transplantation group and the PBS group in colonic gross specimens on the 3rd and 7th day after transplantation. On the 14th day after transplantation, mucosal congestion, edema, erosion and no obvious ulcers were observed in the colonic specimens of the transplanted rats, and DAPI labeled BM-MNCs cells were observed in the colonic tissues of the rats on the 14th day after transplantation by fluorescence microscope. Conclusion BM-MNCs transplantation can promote the repair of colon tissue damaged by UC in rats.
