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.
将单层培养(第3 - 6代)的胸腺、骨髓和脾脏来源的基质机械细胞,按照米舍尔和达顿的方法加入兔脾细胞悬浮培养物中,到培养第4天时,对空斑形成细胞(PFC)的积累产生了显著影响。它们的作用明显取决于剂量。剂量为2.1×10³ - 6.25×10⁵的骨髓来源的基质机械细胞会抑制培养物中PFC的形成。剂量为2.75×10³ - 8×10⁵的胸腺来源的基质机械细胞会使PFC数量增加;剂量为2.1×10³ - 1.3×10⁴的脾脏来源的基质机械细胞未引起任何显著变化,但当剂量增加到8×10⁴ - 6.25×10⁵时,PFC的形成受到抑制。大部分活细胞和PFC存在于游离细胞部分。
