发明一种组织微阵列供体取样与受体蜡块制作的新器具和新方法 . 利用这种新器具和新方法成功地制作了分别含 448 和 390 个供体组织点阵的组织微阵列受体蜡块和切片 . 这种新方法制作的组织微阵列切片经 H&E 染色,显微镜下观察证实,所有切片均无供体点阵组织脱落,切片厚度适中,组织结构无挤压变形,细胞形态均匀一致 . 免疫组化检测 P53 和 P16 蛋白在组织微阵列切片与其相应的常规组织切片中的表达结果完全一致 . 这种组织微阵列供体取样与受体蜡块制作新器具和新方法成本低廉,操作简便,具有在实验室推广应用的价值 .
One novel tool and new methods used to punch the graft tissues and make the receptive blocks for constructing the tissue microarrays (TMAs) were devised. Two kinds of receptive blocks of TMAs consisting 390 and 448 spots of the graft tissues respectively were made successfully by the novel tool and new methods. These two kinds of TMAs sections had no loss of tissue spot. The H&E staining TMAs slides, which were observed under the light microscope, showed that the morphologic structure of all graft tissues had not be changed by punching, and the sections were appropriated thickness with symmetrical cells morphology. The positive expressions of P53 and P16 proteins in specimens of general sections were well consistent with that in TMAs sections by immunohistochemistry. The new tool and novel methods to punch the graft tissues and make the receptive blocks for constructing TMAs, which have many advantages such as low expense, easy operation, convenience and practicality, might be popular in future of the practical application in laboratory.
