Abstract

method for determining collagen in tendon by reversed-phase high performance liquid chromatography (RP-HPLC) was developed. After hydrolysis with hydrochloric acid, the collagen in samples was decomposed into hydroxyproline which hydroxyproline can be derivatized with 2, 4-dinitrochlorobenzene for the determination by HPLC (reversed-phase C18 column, 0.01 mol/L NaAc-HAc (pH 6.0)-CH3CN (80: 20, v/v) as mobile phase, detection at 360 nm). The factors influencing hydrolysis, derivatization and HPLC analysis were studied and optimized. Sixty samples were analyzed with the proposed method. The linear range was from 3 microg/L to 100 mg/L and the detection limit was 3 microg/L. The relative standard deviation (RSD) of determination was 1.95 %. The recoveries of spiked samples were 98.4%-110.8%. The results show that the method is sensitive, accurate and suitable for tendon determination.

Abstract

Objective To explore the feasibility of constructing tissue engineering fat in vitro using human adipose mesenchymal stem cells (hADSCs) and genipin-cross-linked type I collagen. Methods Well-growing third-generation h ADSCs were selected and induced to differentiate into hemangioendothelial cells. h ADSCs and induced vascular endothelial cells were inoculated on the scaffold material at a ratio of 4:1 and co-cultured as group A, h ADSCs alone were inoculated as group B, and induced vascular endothelial cells were inoculated alone as group C. After the three groups of cells were inoculated on the scaffold material, adipogenesis was induced for 5 to 7 days. The cell-scaffold complex was stained with Oil Red O, and the adipogenesis-specific gene peroxisome proliferator-activated receptor ¦Ã was detected by reverse transcription-PCR. -2 (PPAR¦Ã-2) expression, and scanning electron microscopy to observe the growth of cells on the scaffold material. Results: All three groups of cells grew well on the material. Reverse transcription-PCR could detect the expression of PPAR¦Ã-2 in the complexes of groups A and B, but no expression of PPAR¦Ã-2 in group C; Oil red O staining showed that after adipogenesis induction, both groups A and B successfully induced the production of a large amount of mature There was no adipocyte formation in group C. There was a statistically significant difference in the number of adipocytes on the scaffold materials between groups A and B and group C (P<0.01). Conclusion After induction and differentiation of h ADSCs into hemangioendothelial cells, they are co-cultured with h ADSCs seeded on the scaffold material. After adipogenesis induction, mature adipoid cells can be generated in the genipin cross-linked type I collagen scaffold material.

Abstract

Objective To explore the effects of different concentrations of isopsoralen on the proliferation of mouse embryonic preosteoblasts (MC3T3-E1), the expression levels of type I collagen and AP-1 subunit c-Jun and its relationship with primary bone quality Porosis relationship. Methods Cells were divided into normal control group and different concentrations of isopsoralen groups. MTT method was used to detect the proliferation of osteoblasts (MC3T3-E1), Sirius red staining method was used to detect the collagen content of the cell layer, Western-Blot was used to detect c-Jun and RT-PCR was used to detect the expression of type I collagen mRNA. Results Stimulation with different concentrations of isopsoralen can significantly promote the proliferation of MC3T3-E1, increase the collagen content of the cell layer, gradually enhance the expression of c-Jun protein and increase the expression of type ¢ñ collagen mRNA, and the differences are statistically significant (P<0.05 ). Conclusion Isopsoralen may play its role in preventing and treating osteoporosis by promoting the expression of nuclear transcription factor c-Jun, thereby promoting collagen synthesis.

Abstract

In order to explore the improving effect and mechanism of marine collagen peptide (MCP) on the learning and memory of the elderly, 20-month-old female C57BL/6J mice were selected and randomly divided into an elderly control group and three MCP intervention groups. They were fed with 0 and 0.22 MCP respectively. %, 0.44% and 1.32% MCP specially processed feed, and a 3-month-old young control group were fed with ordinary mouse growth feed. After 6 months of intervention, the jumping platform test and Morris water maze test were used for behavioral testing; nissl staining The morphology of the hippocampus was observed; the superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the livers of each group of animals and the expression of brain-derived neurotrophic factor (BDNF) in the hippocampal tissue were also detected. The results showed that the spatial learning and memory ability and passive avoidance ability of aged mice were significantly improved after MCP intervention; the liver SOD activity of mice in the 0.44% MCP intervention group was significantly higher than that of the aged control group, while the MDA content was significantly reduced; 0.44% and 1.32% MCP The expression of BDNF in the hippocampus of mice in the intervention group was higher than that in the elderly control group. There was no significant change in the number of hippocampal neurons in each group of animals. Therefore, marine collagen peptide has the function of preventing age-related decline in learning and memory abilities, and its mechanism of action may be antioxidant activity and promotion of BDNF expression.
