  • Title: [Stromal fibroblasts of the hematopoietic organs and antibody formation in cultures].
    Author: Sidorenko AV, Kulagina NN.
    Journal: Biull Eksp Biol Med; 1978; 86(7):49-51. PubMed ID: 567073.
    Abstract:
    The thymus, bone marrow- and spleen-derived stromal mechanocytes from the monolayer cultures (3rd--6th passages) when added to the suspension cultures of rabbit spleen cells according to Mishell and Dutton produced a considerable effect on the plaque-forming cells (PFC) accumulation by the 4th day of cultivation. Their action distinctly depended on the dose. Bone marrow-derived stromal mechanocytes in doses of 2.1 X 10(3)--6.25 X 10(5) caused inhibition of PFC formation in cultures. Thymus-derived stromal mechanocytes in doses of 2.75 X 10(3)--8 X 10(5) cause an increase in number of PFC; spleen-derived stromal mechanocytes in doses of 2.1 X 10(3)--1.3 X 10(4) failed to bring about any significant changes, but when the dose was increased to 8 X 10(4)--6.25 X 10(5) the inhibition of PFC formation took place. Most of the live cells and PFC were found in the free cells fraction.
