ABSTRACT
Proliferation kinetics and spontaneous yield of chromosomal aberrations phytohemagglutinin (PHA)-responsive peripheral blood lymphocytes were studied from blood samples collected from 45 individuals in 4 different synthetic media. Except for a significant difference for Eagle's MEM and RPMI 1640, the other media did not show difference for the yield of chromatid or chromosome type of aberrations. Differences were however noticed in the proliferation kinetics (mitotic and proliferative rate indices) of cells among the media used. The study indicated that (i) the intrinsic properties of media which influence proliferation rate and yield of chromosomal aberrations are independent of each other as higher proportion of first division cells do not correspond with higher frequency of chromosomal aberrations, (ii) the amount of free-radical scavengers present in the medium, apart from the genetic make-up of the individuals, may contribute to the spontaneous yield of chromosomal aberrations and (iii) RPMI 1640 medium, which showed higher transformation and faster cycling rate for the lymphocytes, may be considered as medium of choice for analysing two main cytogenetic end-points, chromosomal aberrations and sister chromatid exchanges (SCEs).
