In vivo cell kinetics in breast carcinogenesis
Bai, M.; Agnantis, N. J.; Kamina, S.; Demou, A.; Zagorianakou, P.; Katsaraki, A.; Kanavaros, P. (2001)Background: Disruption of the balance between apoptosis and proliferation is considered to be an important factor in the development and progression of tumours. In the present study we determined the in vivo cell kinetics ... -
