    Assessing the quality of donor cells: karyotyping methods

    No full text
    Chapitre 7Somatic cell nuclear transfer (SCNT) has a low success rate that rarely exceeds 5 %. Moreover, SCNT requires highly technical skills and may be influenced by the biological material used (oocyte and donor cell quality). Hence, it is crucial to check the normality of the donor cell’s karyotype. Numerical and structural chromosome abnormalities are detected by cytogenetic analysis at minimum using G-banding to identify the chromosomes. Here, we describe the classical protocols that are needed to perform complete cytogenetic analyses, i.e., G-banding to identify chromosome aberrations, followed by Fluorescent In Situ Hybridization (FISH) of specific probes for a more sensitive detection and precise identification of the rearrangement
