Aim. To develop the protocols for liver and kidney tissue decellularization, and to develop an analysis of the proliferative activity of human Hep-G2 hepatocarcinoma cells on various carriers.Materials and methods. Decellularization of the liver and kidneys was performed by perfusion of detergent solutions with gradually increasing concentrations of Triton X-100 (1, 2 and 3%). A histological analysis of the obtained samples was performed, and the method of optical and scanning electron microscopy was used to study the obtained samples. The proliferative activity of human Hep-G2 hepatocarcinoma cells was studied on the obtained samples of decellularized liver and kidney tissue.Results. Decellularization of the organ does not lead to changes in the specific structure of the tissue matrix. Microparticles with an average size of 200 μm were made from their decellularized matrix of liver and kidney tissues. The level of proliferative activity of human Hep-G2 hepatocarcinoma cells cultured on microparticles from a decellularized liver was significantly higher than on microparticles from a decellularized kidney.Conclusion. The decellularized matrix retains the native three-dimensional structure of the tissue. The level of cell proliferative activity is significantly higher on microparticles from the decellularized liver, which confirms the preservation of the specificity of the extracellular matrix of the tissue after the process of decellularization. |
