Abstract
The effect of the Xymedon conjugate with methionine on blastema regeneration in Schmidtea mediterranea planarians was investigated. It was established that the preparation has low toxicity towards planarians, which is evidenced by its CL50 values (lethal concentration). The results of the vital computer morphometry and flow cytofluorometry confirm that Xymedon with methionine induces regeneration at high concentrations only: 0.01 g/100 mL, 0.05 g/100 mL, and 0.1 mg/100 mL. Low concentrations of the preparation have no influence on blastema regeneration in planarians.

Schmidtea mediterranea planarians are well-known objects for the study of regeneration in the world. The formation of the blastema is always reached by cutting off the edges of the planarian body. Blastema formation occurs due to migration and division of neoblasts—pluripotent cells. Planarians have a very simple nervous system and do not have the sensitivity like mammals. All planarians used in the experiment survived and restored their front ends with eyes.
