[Comparative study of the proliferative activity of native and cryopreserved colony-forming units in humans and mice].

The agar culture method was used to state that colony-forming units responsible for cell structures of a hemopoietic series remained undamaged after cryopreservation (-196 degrees) in a suspension of mouse and human donor bone marrow. Cultivation of cryopreserved bone marrow revealed the inhibition of proliferative activity of cells growing in agar as compared with native ones. The inhibition of DNA synthesis was the basis of this process.

[Cellular structures formed during bone marrow cultivation in agar].

The growth-enhancing effect and the differentiation of colonies formed by native and frozen-thawed myelokaryocytes in semiliquid agar were observed over a period from the 2nd to the 28th day. The cultivation of bone marrow in agar was shown to form colonies consisting of haemopoietic cells as well as of stromal elements. Under the cultivation of frozen-thawed bone marrow, the retardation of proliferative activity of growing cells was observed within up to 4 days. Later on the proliferative character and the rate of the myelokaryocytes of both the types were seen identical. The question of a possible existence of haemopoietic tissue and stromal elements in the progenitor cells of normal bone marrow is being discussed.

[Macrophage reaction in the bed of an allogeneic skin transplant].

The character of cell reactions, number of macrophages at the place of skin allograft was demonstrated to depend on the stage of posttransplantational period. Macrophagal reaction increases as the crisis of rejection is approaching; functional and metabolic activity of macrophages is increasing that is evident from an intensive vacuolization of cytoplasm, decreased contents of glycogene, enhanced acid phosphatase activity in them, increased amount of H3-thymidin labelled cells.

[Effect of low-temperature preservation on the proliferative activity and topography of the dissemination of donor and cadaveric colony-forming units (CFU) in an irradiated organism].

Investigation carried out by means of chromosome marker T6T6 showed that frozen donor and cadaver bone marrow cells (6 h and 12 h after death) survive and proliferate in the organism of lethally irradiated recipient; the proliferation and differentiation intensity of cadaver cells is reduced in comparison with the donor cells.
