[Changes in the karyotype and surface properties of L cells during the adaptation of a suspension culture to monolayer growth].

Distribution of cells (L929, LS, LSM) in the two-phase polymer system was studied in addition to characterization of their karyotypes. In the course of LSM cell passages, the increased ratio of cells with a reduced number of chromosomes was found. The results obtained show that in the process of adaptation of the suspension cell culture to the growth as monolayer (the culture of LSM cells) the changes of the cell surface do not dependent on the chromosome number.
