The use of biodegradable polymers in design of cellular scaffolds.
The objective of this work was to demonstrate the usage of biodegradable polymers, made of calcium alginate and dibutyrylchitin, in the design of cellular scaffolds having broad application in reconstructive therapy (dentistry, orthopedics). To visualize cells seeded on calcium alginate and dibutyrylchitin polymers DAPI staining of fibroblasts nuclei was used. The cytotoxicity of the materials and microscopic evaluation of the viability of seeded cells was tested with a PKH 67 fluorescent dye. To assess the cellular toxicity the proliferation of fibroblasts adjacent to the tested polymers was examined. The vitability of cells seeded on polymers was also evaluated by measuring the fluorescence intensity of calcein which binds only to live cells. The conducted experiments (DAPI and PKH 67 staining) show that the tested materials have a positive influence on cell adhesion crucial for wound healing - fibroblasts. The self-made dibutyrylchitin dressing do not cause the reduction of viability of cells seeded on them. The in vitro study illustrated the interactions between the tested materials, constructed of calcium alginate or dibutyrylchitin and mouse fibroblasts and proved their usefulness in the design of cellular scaffolds. Examined polymers turned out to be of great interest and promise for cellular scaffolds design.
