[Thiophosphamide-induced chromosome aberrations in embryonal liver and bone marrow cells of A/He and C57BL/L mice]

Chromosomal aberrations were studied in cells of embryonic liver and bone marrow of A/He and C57BL/6 mice following mutagenic treatment by the alkylating agent thiophosphamide in g1-S periods of the cell cycle. Higher sensitivity of chromosomes to aberration induction was found in A/He mice.
