We have isolated and characterized cDNA clones coding for the H1 histone subtype H1(0) in mouse teratocarcinoma cells. The mRNA is 2100 nt long and contains a coding sequence which is highly related to that of the human H1(0) gene. Using this cDNA as a probe, we have shown that, in comparison to undifferentiated F9 cells, differentiated F9 teratocarcinoma cells contain large amounts of H1(0) mRNA. This increase takes place very early during differentiation and does not correlate with changes in the rate of cell division. This indicates that the accumulation of H1(0) mRNA is not the result of reduced proliferation. Most likely on the contrary, the increase in the amount of H1(0) and the resulting effects on the formation of high order chromatin structures are parts of the differentiation program induced in F9 cells.
