Cultures of multipotent mesenchymal stromal cells from the pulp of human deciduous teeth (SHED cells) were characterized. The cells were used for population of 3D biodegradable polylactoglycolide scaffolds; their osteogenic potential was preserved under these conditions. Implantation of the scaffolds to mice induced no negative reactions in the recipients. These results suggest that the use of polylactoglycolide scaffolds populated with SHED cells is a promising approach for creation of implants for bone defect replacement.

Mesenchymal stromal cells from deciduous teeth in 2D- and 3D-cultures on culture plastic, silicate glass, porous polystyrene, and experimental polylactoglycolide matrices were visualized by scanning electron microscopy with lanthanide contrasting. Supravital staining of cell cultures with a lanthanide-based dye (neodymium chloride) preserved normal cell morphology and allowed assessment of the matrix properties of the carriers. The developed approach can be used for the development of biomaterials for tissue engineering.

We proposed a novel method of generation of bioresorbable polymeric scaffolds with specified architectonics for tissue engineering using extrusion three-dimensional (3D) printing with solutions of polylactoglycolide in tetraglycol with their subsequent solidifying in aqueous medium. On the basis of 3D computer models, we obtained the matrix structures with interconnected system of pores ranging in size from 0.5 to 500 µm.
