Methods In situ method of terminal deoxytransferade-mediated dUTP-biotin nick and labelling staining was used to identify programmed cell death in 20 KAs. These cases also were examined with immunohistochemical technique for the expression of two protooncogenes, bcl-2 and bax, recently recognized to be involved in apoptosis.

用末端脱氧核苷酰转移酶介导的d-UTP生物素缺口末端标记技术，原位检测20例角化棘皮瘤中凋亡细胞；应用免疫组织化学技术检测皮损部位bax和bcl-2基因产物的表达。

The higher contract rate and the quicker healing speed appeared in treat group. The result from the hematoxylin and eosin staining showed that the epidermis is thicker in treat group than that in control group. A few BrdU positive cells appeared on the hair follicle of the rengenerate skin and the stratum basale and the stratum of the rengenerate epidermis.

Stratum granulosum: outside the Spinous layer, made up of cells further differentiated to cuticle cells, so it would lose the nucleolus and turn to the enucleated startum lucidum and horny layer after completely cornified to horny layer.

颗粒层：位于棘层之外，是进一步向角质层细胞分化的细胞，因此它起着向角质层完全角化后，便失去细胞核，而转化成无核的透明层和角质层。

Gliosis is resulted in TLE. The synapse consists of the presynaptic and postsynaptic terminals, which in many synapses are surrounded by glial cell.

颞叶癫痫可导致神经系统胶质增生，突触后终端与胶质细胞之间形成突触，突触后终端的树突棘的形态学的变化引起突触结构的改变，与胶质细胞之间形成的突触为异位突触，引起海马内环路性质的变化，从而提高致痫性。

The number of filopodia and microspikes of HeLa-fascin cells was decreased and the cells grew together.

在HeLa细胞中，反义封闭fascinl基因后，细胞的丝状伪足和微棘减少，表现为聚集生长。

METHODS: Bone marrow was extracted from the anterior supervior iliac spine or the posterior superior iliac spine of canines of the cell transplantation group through puncture. BM-MNCs were isolated by the Ficoll density gradient isolation, and labeled with CM-DiI.

细胞移植组于髂前上嵴或髂后上棘穿刺抽取骨髓，经Ficoll密度梯度离心法分离获取骨髓单个核细胞，行CM-DiI标记。
