  • Title: Serial cell culture and cytogenetic studies of marrow cells from a patient with monosomy 7 syndrome.

    Abstract:
    Serial bone marrow cell culture studies, with cytogenetic characterization, were performed in an 18-month-old boy with monosomy 7 syndrome--a condition that usually converts to nonlymphoblastic leukemia. Over a 12-month course, his marrow demonstrated: decreased colony formation and increased cluster formation in vitro with disease progression (consistent with preleukemia); persistence of only the monosomy 7 karyotype in direct marrow studies; and in contrast, proliferation of both 46,XY and monosomy 7 cells in in vitro marrow cultures. The findings indicate that certain dormant marrow cell populations may be expressed under in vitro culture conditions and suggest the need for determining factors which would allow their expression in vivo.
