Modulation of Adhesion and Migration of NIH/3T3 Cells in Collagen Materials by Taxifolin Derivatives

One of the urgent tasks of tissue engineering is the development of stable non-toxic materials that support cell migration during tissue regeneration. This study was aimed at obtaining new gel materials based on collagen and derivatives of taxifolin, taxifolin pentaglutarate and a conjugate of taxifolin with glyoxylic acid and investigating their properties. It was shown that an increase in the proportion of polyphenols in the gel led to a decrease in the rate of degradation of the material. The obtained materials did not negatively affect the viability of NIH/3T3 mouse fibroblasts. The cells were attached to the surface of the materials and spread out on the surface of the material containing taxifolin pentaglutarate. It was also found that fibroblasts migrated through the obtained materials. An increase in the proportion of the conjugate of taxifolin with glyoxylic acid in the material led to inhibition of migration through the material, whereas an increase in the proportion of taxifolin pentaglutarate in the material, on the contrary, led to a significant increase in cell migration through the material. The results obtained indicated the possibility of modulating cell adhesion and migration in biomaterials by including various taxifolin derivatives in their composition. Thus, materials obtained on the basis of collagen and taxifolin derivatives may be of interest for regenerative medicine.
