Abstract During the past years in vivo transplantation experiments and in vitro colony-forming assays indicated that tumors arise only from rare cells. These cells were shown to bear self-renewal capacities and the ability to recapitulate all cell types within an individual tumor. Due to their phenotypic resemblance to normal stem cells. the term "cancer stem cells" is used. https://hollandscountryclothinges.shop/product-category/glitter-spray/
