Original abstract
Malignant cells appear to possess a special aptitude for survival. We attempted to prove this in vitro by an acute nutritional and energy deprivation as a survival threat. A phosphate-buffered saline (PBS) survival test in cell culture allowed static observations. These were supplemented by classic and quantitative phase-contrast time-lapse microscopy. From one normal and four neoplastic cell populations, no cells survived 77 hours exposure to PBS. Only G3S2 derived from a human breast carcinoma survived 60 hours. Cells in sparse culture were more vulnerable than those in dense. Epithelial cells were more vigorous than mesenchymal cells. Cells of greater malignancy resisted longer. Evaluation in culture as detailed by digital holographic microscopy (DHM) revealed an increase in the compactness of the intracellular mass motility from normal to metastasizing mesenchymal cells, thus reaching the level of epithelial G3S2 cells. Studying the PBS survival test with DHM opens a new approach to investigations of the structural integrity of neoplastic cells.

Zdá se, že maligní buňky mají speciální schopnost pro přežití. Pokusili jsme se to dokázat pomocí akutního nutriční a energetické deprivace in vitro. Test přežití za přítomnosti PBS (phosphate-buffered saline) v buněčné kultuře byl proveden statickým pozorováním, které bylo doplněno klasickou a kvantitativní fázovou časosběrnou mikroskopií. Z jedné normální a čtyř neoplastických populace buněk žádná enpřežila vystavení PBS 77 hodin. Pouze G3S2 odvozené od lidského prsního karcinomu přežily 60 hodin. Buňky v řídkém porostu byly více zranitelné než ty v hustém. Epiteliání buňky byly aktivnější než mesenchymální. Více maligní buňky odolávaly déle. Evaluace kultur digitální holografickou mikroskopií (DHM) odhalila nárůst v kompaktnosti vnitrobuněčné motility od normálních k mesenchymálním metastazujícím buňkám téměř dosahujícím úrovně epiteliálních G3S2. Studium PBS testu přežití pomocí DHM otevírá nové možnosti výzkumu strukturální integrity neoplastických buněk.
