Three-dimensional model of biomatrix as a method of studying blood vessels and nerve growth in tissue engineering structures

Abstract

The method involves isolating and culturing ex vivo cultures of mouse dorsal root ganglia and abdominal aorta in a three-dimensional gel (Matrigel). Unlike other explant cultures, this technique allows to study the physiological and biochemical processes in the tissue explants of dorsal root ganglia and abdominal aorta in three-dimensional space but in contrast to a two-dimensional adhesive culture. Administration of the tested substances to the Matrigel allows analyzing their effects on the growth of blood vessels and neurites from the explants for 21 days. The developed method can be applied in modern cardiological and neurobiological research and explores how new therapeutic agents can accelerate the regeneration of blood vessels and nerves.
