利用扫描电镜观察13例人食管鳞癌。自肿瘤、增生细胞及正常粘膜部位分别取样品26个、26个及13个。食管的正常粘膜、增生细胞及瘤细胞之间的表面差别非常明显。食管癌细胞在扫描电镜上的表面特征为失去正常的微嵴和细胞间嵴,形成畸形的微绒毛及细胞突起,具有很多微凹,小圆形癌细胞间无紧密的连接。 Using scanning electron microscopy to observe 13 cases of human esophageal squamous cell carcinoma. Twenty-six samples, 26 samples, and 13 samples were taken from tumor, hyperplastic, and normal mucosa sites. The surface difference between normal mucosa, hyperplastic cells, and neoplastic cells of the esophagus is very obvious. The surface features of esophageal cancer cells on the scanning electron microscope are the loss of normal microvulnases and intercellular spasm, the formation of malformed microvilli and cell protrusions, with many dimples, and no tight junctions between the small round cancer cells.
