Abstract:
Objective: To investigate the relationship between tumor angiogenesis and renal cancer stem cells. Methods: The primary cell culture method was used to extract and isolate RCSCs, and then qRT-PCR and Western blot methods were used to detect the expression levels of the kidney cancer stem cell markers CD105 and Sox2 genes and proteins from different MVD kidney cancer tissues. Using TCGA database, analyze the correlation between tumor angiogenesis markers and tumor stem cell regulatory genes. Results: The stem cell markers CD105 and Sox2 genes in RCSCs derived from high MVD kidney cancer tissues were respectively increased by (2.34±1.77) times and (3.92±1.41) times (PCD105<0.01, PSox2<0.05)and protein levels were increased by (5.12±3.31) times and (4.90±3.30) times(PCD105<0.05, PSox2<0.01).Meanwhile,up to 30% of stem cell promoting stemness regulatory genes are positively correlated with angiogenesis genes CD31/PECAM1 and KDR, and 64 genes are also strongly positively correlated with CD31/PECAM1 and KDR genes. Conclusion: The high microvessel density of kidney cancer is strongly correlated with the existence of renal carcinoma stem cells.

Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
