肿瘤的组织结构多种多样,其中间质成分起支持和营养作用,实质是肿瘤的主要成分,决定肿瘤的生物学特点。通常根据肿瘤的实质形态来识别肿瘤的组织来源,并根据其分化成熟程度和异型性大小来确定肿瘤的恶性程度。随着对肿瘤实质细胞研究的深入,科学家发现其中含量较少的部分实质细胞与干细胞在表面标志和生物学特性上有很多相似之处,具有特殊的生物学行为,与肿瘤的生长、转移、耐药和复发关系密切,并由此推断肿瘤是由干细胞增殖分化失调引起,并
Tumor tissue structure varied, including the role of stroma support and nutrition, in essence, is the main component of the tumor, the biological characteristics of the tumor. According to the actual form of the tumor to identify the source of tumor tissue, and according to their degree of differentiation and atypia size to determine the degree of malignancy. With the deepening of research on tumor parenchyma cells, scientists found that some of the less parenchymal cells and stem cells have many similarities in surface markers and biological characteristics, and have special biological behaviors that are closely related to tumor growth, metastasis, Resistance and recurrence are closely related, and thus infer that the tumor is caused by dysregulation of stem cell proliferation and differentiation
