Abstract (original English)

To study the growth of adipose-derived stem cells (ADSCs) planted in three-dimensional (3D) materials, a 3D cultured ADSCs system based on microbial transglutaminase (mTG) enzyme crosslinked gelatin hydrogel was constructed. ADSCs were isolated from the subcutaneous adipose tissue of a Sprague Dawley rat by collagenase digestion and centrifugation, and were cultured for passage. The mTG enzyme crosslinked gelatin hydrogel was firstly synthesized by mixing gelatin and mTG, and then the ADSCs were encapsulated in situ (2D environment) and cultured in the 3D materials (3D environment). The morphology and adhesion of cells were observed by inverted phase contrast microscope. In addition, HE staining and Masson staining were carried out to observe the distribution of cells in the material. Living and death situation of ADSCs in the materials was observed by fluorescence microscope and laser scanning confocal microscopy. Scanning electron microscopy was used to observe the adhesion of ADSCs on hydrogel surface. Alamar-Blue method was used to detect the proliferation of ADSCs in the hydrogel. Moreover, the results were compared between the cells cultured in 2D environment and those in 3D environment. The result of 2D culture showed that ADSCs grew well on the hydrogel surface with normal functioning and had good adhesion. The results of 3D culture showed that ADSCs grew well in 3D cul
