Ploidy effect on the radiation reaction of mammalian cells

Summary The variation of X-ray sensitivity was investigated during the cell cycle. The cells were most sensitive during the S phase and less sensitive during the G₂- and G₁ phase. Furthermore, the repair of X-ray damage was investigated in stationary (plateau phase) cells. The cells of both lines were able to repair damage to nearly the same extent.

Zusammenfassung Die Variation der Strahlensensibilität während des Zellcyclus wurde untersucht. Die Zellen reagierten am sensibelsten in der S-Phase, weniger sensibel in der G₂-und G₁-Phase. Weiterhin wurde die Reparation von Strahlenschäden bei stationären (Plateauphase-)Zellen untersucht. Die Zellen beider Linien sind in etwa gleichem Maße reparationsfähig.
