Agarose overlay selectively improves macrocolony formation and radiosensitivity assessment in primary fibroblasts.

abstract：:To characterize further the radiosensitivity of severe combined immunodeficiency (scid) mice, the induction of micronuclei (MN) in polychromatic erythrocytes as well as cell killing and translocation induction in stem cell spermatogonia was studied. Scid mice turned out to be clearly hypersensitive for X-ray-induced c...
