Cancer stem cells and escape from drug-induced premature senescence in human lung tumor cells: implications for drug resistance and in vitro drug screening models
PublikacjaBadania z użyciem modelu komórek nowotworu płuc A549 wykazały, że komórki te po traktowaniu lekami uszkadzającymi DNA zatrzymują proliferację i wchodzą w stan starzenia komórkowego. Jednak post-inkubacja tych komórek prowadzi do powrotu do stanu proliferacji małej frakcji komórek. Wykazaliśy, że frakcja ta związana jest z obecnością komórek pierwotnych nowotworu w populacji komórek A549. Powrót do stanu proliferacji komóek A549...
