DNA methylation is not increased in mouse-human somatic cell hybrids.
The level of DNA methylation in three mouse-human cell lines that retained different human chromosomes and in the parental mouse and human lines has been determined by high-pressure liquid chromatography (HPLC). The level of methylation is similar in the hybrid and parental cells, indicating that interspecific somatic cell hybridization followed by preferential chromosome segregation can occur without an increase in overall DNA methylation.
