负极性驻极体有促进成纤维细胞凋亡的作用。

Methods: Fibroblast cell were treated with -300,-500 and -1 000V PTFE electrets for 24, 48 and 72 h, respectively, and the influence of negative electrets on cell apoptosis was studied by means of flow cytometry and transmission electron microscope.

Results: Compared with control group, apoptosis cells increased from 0.5%to 10%(some even to 15%) after 24,48 and 72 h action of -300,-500 and -1 000 V electrets. After action of -500 V PTFE electrets for 48-72 h, fibroblast cells showed characteristic morphological features of apoptosis. These features included chromatin aggregation, nuclear and cytoplasmic condensation and partition of cytoplasm and nucleus into membrane bound-vesicles.

Compared with contrasted, the wound healing rate of treatment remarkably improved after 7 days, 14 days, 21 days and 28 days; The histology filleting indicated that the BC could permit the fibroblast and blood capillary to gradually grow into the cellulose pellicle, which interpreted that the BC had therapeutical effect on the skin wound. At last the study of embedding BC under derm indicated that there was no obvious sign of acute immune rejection, slight inflammatory response inducing the organic which lasted short time and gradually extincted till last.

为此，我们选择了易于扩增、易于转染并能稳定表达外源目的基因的成纤维细胞为载体细胞，建立了人〓基因疗法的实验模型，并观察了其体内抗肿瘤作用。

Immunohistochemistry were positive for CD34 in some region where the fibroblast actively proliferated, whereas fibrocytes in mature fibrous tissue were negatively stained.

CD34免疫组织化学染色显示一些增生活跃的纤维母细胞明显表达CD34，成熟的纤维组织内的纤维细胞CD34则为阴性。
