Comparison of ultrastructural features among neuroblastic tumors: maturation from neuroblastoma to ganglioneuroma.

abstract：:The aim of this study is to investigate the effects of betulinic acid (BA) on triple-negative breast cancer MDA-MB-231 cells and observe the ultrastructural changes. The concentration of BA required to induce apoptosis in MDA-MB-231 cells has been previously reported. In this study, a cell counting kit-8 proliferation...
