title: [Origin of fibroblasts and macrophages of skin wound granulation tissue].
abstract: By the method of thymidine autoradiography and fluorescing antibodies, the origin of cells participating in healing the experimentally produced wounds was investigated. 3H-thymidine was administered a day before the production of the wounds. 14C-thymidine was injected impulsively 1 h before the material was fixed 1,3 and 8 days after the trauma. The analysis of the autographs demonstrated that during wound healing the cell-precursors of macrophages and fibroblasts migrate from beyond the limits of the connective tissue. By means of the fluorescing antibodies in mouse radiation xenogenic chimaeras it was demonstrated that macrophages and fibroblasts participating in wound healing take their origin from the donor's elements, that is, are of bone marrow origin.
