23 Jul Method for using Pickering emulsion method for producing GelMA macropore hydrogel and application
Abstract
The invention discloses a method for using a Pickering emulsion method for producing GelMA macropore hydrogel and application. The method comprises the steps of dissolving GelMA and PEG-4SH in PBS buffer liquid, and stirring a mixture; adding MgO nano-particles after fully dissolving the GelMA and the PEG-4SH, stirring a mixture, and conducting ultrasonic treatment on the mixture; adding dodecaneand a photoinitiator, and using a high-speed homogenizer for intensively stirring a mixture to obtain stable Pickering emulsion; and making the emulsion subjected to UV illumination to form gel, and obtaining the GelMA macropore hydrogel by using ethyl alcohol and water for full wash dialysis. The produced GelMA macropore hydrogel has the advantage of the macropore structure, can promote transportation of nutrient substances, discharging of metabolic products and cell communication, entraps a component containing Mg, has effect of promoting adhesion and proliferation of bone marrow mesenchymalstem cells and promoting osteogenic differentiation, has excellent biocompatibility, can be used as a bone tissue engineering scaffold with excellent performance, and has large clinical application potential in the field of bone repair.
