Ultrastructural changes in tumor cells treated with liposomal forms of anticancer drugs
Aim: To determine the main ultrastructural changes in MCF-7 sublines sensitive and resistant to cytotoxic action of anticancer drugs, resulting from the treatment with conventional and liposomal forms of cisplatin and doxorubicin. Methods: Electron microscopy, light microscopy, MTT-test. Results: It...

Conclusion: Evaluating an effect of equal concentrations of cisplatin and doxorubicin in conventional and liposomal forms, one may conclude on higher cytotoxic action of doxorubicin vs. cisplatin that is expressed in a wider spectrum of ultrastructural changes of cell architectonics in different sublines of MCF-7 cells and higher rate of apoptosis. en Інститут експериментальної патології, онкології і радіобіології ім.
