六、癌细胞基因表达的改变肿瘤损害是由许多已经改变了遗传表型,其组织学及生物学性质均与其他细胞不同的细胞所组成。其特点:(1)癌细胞较原来的组织细胞核着色更深,染色质及有丝分裂更多;(2)癌损伤显示对正常组织侵犯的病理性质;(3)癌细胞从肿瘤原来的位置转到另外的组织或器官,即为转移。 (一)癌——一种基因疾病所有细胞都来自遗传上相似类型的细胞。其涵义是一旦某个细胞变成癌细胞,其
6. Changes in gene expression of cancer cells The tumor damage is caused by many cells that have changed their genetic phenotypes and whose histological and biological properties are different from those of other cells. Its characteristics: (1) Cancer cells stained more deeply than the original tissue, with more chromatin and mitosis; (2) Cancer lesions showed pathological properties that invaded normal tissues; (3) Cancer cells were transferred from the original position of the tumor to another The organization or organ is the transfer. (A) Cancer - A genetic disease All cells come from genetically similar types of cells. Its meaning is that once a cell becomes a cancer cell, it
