After 21 days of culturing, the cell-bearing scaffolds (n = 4 per group) were fixed in 4% paraformaldehyde for 2 h. Triton-X (0.1%) was used to soak the scaffolds for 5 min, which were then washed thrice with PBS for 5 min each. Blocking was performed with BSA at room temperature for 1 h. After blotting with water-absorbing paper, primary antibodies (anti-PRG4, anti-CILP, anti-COLII, anti-COLI, and anti-SOX-9) (1:100, Abcam, UK) were added to each sample and incubated at 4 \u00b0C overnight. Following washes with PBS, a corresponding secondary antibody (1: 500, Abcam, UK) was added, incubated at room temperature for 1 h, and washed with PBS.\u00a0The scaffolds were then labeled with FITC phalloidin (1:200, MaoKang, China) and incubated at room temperature for 2 h, followed by incubation with DAPI staining solution (1:1000, MaoKang, China) for 30 min at room temperature. After the final wash with PBS, samples were observed and imaged under a confocal microscope (LEICA, Germany). Analysis and quantification of protein expression was performed using ImageJ.<\/span><\/p>\n

Alamar Blue was bought from Maokang Biotechnology Co., Ltd., (Shanghai, China).\u00a0To detect cytotoxicity and cell proliferation, the rBMSC suspension was added to the wells from the top of the scaffold, and culturing took place in a cell incubator at 37 \u00b0C for 1, 4, or 7 days. After the end of the culturing, we added Alamar blue reagent to the well plate and continued incubating in the cell incubator for 2\u20138 h until the color of the culture medium changed from blue to pink. Finally, the fluorescence intensity which is directly proportional to the number of viable cells was measured by a fluorescence photometer (SAFIRE, Tecan Co., Mannedorf, Switzerland).\u00a0<\/span><\/p>\n

Streptozotocin was provided by Shanghai Maokang Biotechnology Co., Ltd. (Shanghai, China). Sixty rats were single-cage raised in the condition avoiding strong light and noise (temperature 22 \u00b1 2 \u00b0C; humidity 40-70%; 12\/12-h day-night cycle; free to feed and water). After one week of adaptive feeding, 10 rats were randomly selected as the control group, which were fed with standard diet. The remaining 50 rats were fed with high-fat and high-sugar diet (20% sucrose, 18% lard, 3% yolk and 59% basic diet) for 4 weeks. The rats were fasted for 12 h, followed by single intraperitoneal injection of streptozotocin solution with dose of 30 mg\/kg. After 72 h, the blood sample was taken from tail vein, and the fasting blood glucose (FBG) was detected. The FBG > 16.7 mmol\/L presented the successful establishment of T2DM model.<\/span><\/p>\n
