[Differential reaction of condensed and diffuse chromatin to polyamines. I. Reaction of interphase nuclei chromatin to putrescine].
Condensation of the interphase nuclei chromatin under putrescine treatment was studied in cultured human fibroblasts 46, XX: 47, XXX: 49, XXXXY, and aneuploid cells of the Chinese hamster. The effect was tested separately for diffuse and condensed chromatin. Putrescine treatment did not affect the percentage of cell nuclei with X-chromatin bodies in the human cell strains while significantly increasing the percentage of nuclei with coarse chromatin network and chromocenters. In cultured Chinese hamster cells, putrescene did not change the percentage of nuclei with identified chromocenters and no significant condensation of diffuse chromatin was observed either.
