title: [Recovery of continuous cells following prolonged storage at the temperature of liquid nitrogen].
abstract: The recovery process of HeLa continuous cells after prolonged storage at nitrogen liquid temperature (--196 degrees C) has been analysed. The karyologic analysis evidence indicates a high stock cell karyostability. A study of cell division, generation cycle parameters and DNA synthesis by autoradiography demonstrated cell adaptation to a continuous passage to be due to the increase of proliferative pool and to the intensitification of generation processes in the multiplicated population. Cell structure changes during adaptation were reversible.
