[Effect of a benzopyrone compound on embryonic tissue and cell cultures (author's transl)]
Abstract:
Embryonic tissues and cells of the chicken were treated with a coumarin-rutin derivative preparation (Venalot). A total of 3000 cultures from embryonic epithelia, skeletal muscle tissue, and connective tissues were tested. At high dosages, never administered in the therapy, the preparation inhibited the cell proliferation strongly. With the diminution to therapeutical concentrations no longer inhibitory but stimulatory effects, viz. to mitosis, were revealed. High cell partition rates in the connective tissue (fibroblasts), in the epithelial cells and in the bony tissue of the embryonic os frontale (osteoblasts) are an indication of the mechanism of the known wound-healing accelerating action of the preparation. The effect of stimulating the proteolytic action in mesenchymal cells, observed on isolated peritoneal macrophages has been confirmed for the mesenchymal cell of the embryonic chicken.
Insights
This study shows that a coumarin-rutin derivative (Venalot) stimulates cell mitosis and proliferation at therapeutic doses. This mechanism explains its wound-healing acceleration effects in embryonic chicken tissues.
Area of Science:
- Pharmacology
- Developmental Biology

Purpose:
- To elucidate the cellular mechanisms underlying the wound-healing properties of Venalot.
- To determine the dose-dependent effects of Venalot on cell proliferation.
- To confirm the stimulatory effect of Venalot on proteolytic action in mesenchymal cells.
Summary:
- Embryonic chicken epithelia, skeletal muscle, and connective tissues were cultured and treated with Venalot.
- High doses inhibited cell proliferation, while therapeutic concentrations stimulated mitosis.
- Increased cell division rates in fibroblasts, osteoblasts, and epithelial cells were observed, indicating a wound-healing mechanism.
Impact:
