title: [Effect of opioid peptides on proliferation and differentiation of skeletogenic cells of rabbit bone marrow in vitro].
abstract: The influence of opioid peptides DSLET and DAGO in doses 10(-5), 10(-7) or 10(-10) mg per 1 ml of the medium on colony formation in the culture of stromal bone marrow fibroblast precursors was investigated 5. 10(-6) bone marrow cells were placed in plastic containers (Costar). 12 day old cell cultures were fixed with ethanol and stained with hematoxyline-eosin. Effectiveness of fibroblast colony formation (EFFC) was detected. Grown fibroblast colonies were stained after Gomory for alkaline phosphatase. Opioid peptides DSLET and DAGO in the used doses exerted no influence on EFFC and percentage phosphatase-positive colonies, which casts doubt on a presumable direct action of opioid peptides on stromal bone marrow cell-precursors. But it does not seem unlikely that opioid peptides may affect stromal bone marrow precursors of fibroblasts through the cell environment, particularly, via macrophages.
