Abstract

The T1 and T2 relaxation times of water protons in two cell types in culture derived from Syrian hamster fetuses (normal primary or secondary fetal cells vs BP6T tumor cells derived from the normal cells transformed by carcinogens) were measured at 7.05 Tesla magnetic field (proton frequency = 300 MHz). The T1/T2 ratios and the correlation time, tau c, calculated from the T1/T2 ratio of cellular water protons, are significantly different in these two fibroblastic cell types of the same biological origin and with similar morphologies and growth rates in culture.
