To reconcile major drawbacks of 2D planar culturing system, we innovatively developed an automated closed industrial scale cell production (ACISCP) platform based on GMP-grade microcarrier for culture of umbilical cord-mesenchymal stem/stromal cells (UCMSCs), in accordance with the criteria of stem cell bank. ACISCP system is a fully closed system, which employs different models of vivaSPIN bioreactors (CytoNiche Biotech, China) for scale-up cell culture and vivaPREP (CytoNiche Biotech, China) for automated cell harvesting and cell dosage preparation. To realize industrial scale expansion of UCMSCs, a three-stage expansion was conducted with 1 L, 5 and 15 L vivaSPIN bioreactors. Using 3D TableTrix^® and ACISCP system, we inoculated 1.5 × 10⁷ of UCMSCs into 1 L vivaSPIN bioreactor and finally scaled to two 15 L bioreactor. A final yield of 2.09 × 10¹⁰ cells with an overall expansion factor of 1975 within 13 days. The cells were harvested, concentrated, washed and prepared automatically with vivaPREP. The entire process was realized with ACISCP platform and was totally enclosed. Critical quality attributes (CQA) assessments and release tests of MSCs, including sterility, safety, purity, viability, identity, stability and potency were performed accordingly. The quality of cells harvested from 3D culture on the ACISCP and conventional 2D planar culture counterpart has no significant difference.

In the present study, we evaluated the effects of a conditioned medium of amniotic fluid-derived stromal cells (AFSC-CM) on bone metabolism. In mice, intraperitoneal injections of AFSC-CM increased bone mass and enhanced bone turnover. The precursor populations of myeloid and mesenchymal lineages, as well as endothelial cells in bone marrow, were also augmented by AFSC-CM administration. In an in vitro culture experiment, AFSC-CM increased osteoclast differentiation of bone marrow-derived macrophages, but had no significant effect on the osteogenic differentiation of preosteoblasts. However, AFSC-CM administration dramatically accelerated the migration and tube formation of endothelial cells, and a cytokine array showed that AFSC-CM contained many angiogenic factors. These results indicate that AFSC-CM exerts a bone anabolic effect by changing the bone marrow microenvironment, including angiogenesis and precursor expansion. Therefore, ameliorating marrow angiogenesis is a potential therapeutic strategy for bone regeneration, for which AFSCs can be a good cellular source.</p>","PeriodicalId":202,"journal":{"name":"Journal of Tissue Engineering and Regenerative Medicine","volume":"16 10","pages":"923-933"},"PeriodicalIF":3.3,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"6196890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this goal, we fabricated a microchip using a 3D printed template with adjustable heights.

The evaluation was performed by applying the questionnaires Western Ontario McMaster Universities, Short Form Health Survey 36 and Visual Analog Pain Scale, also by analyzing the synovial fluid (inflammatory cytokines, enzymatic, colorimetric and viscosity analysis), this evaluation happened in two moments: before the surgical procedures and after 6 months of the interventions and also was made a comparison to standard arthroscopy.

In the evaluation of inflammatory cytokines, there was a significant reduction in the cytokine IL-1b only in the ADSCs + PRP group (46%) and ADSCs (31%), of IL-6 in the ADSCs + PRP group (72%), of IL-8 in the ADSCs + PRP group (50%) and ADSCs (31%), and TNF in the ADSCs + PRP group (46%). There was also a significant increase in the amount of total proteins (79%) in the control group and polymorphonuclear cells (47%) in the ADSCs + PRP group.

This motivated us to review the randomized clinical trials that examine the effectiveness and safety of PRP, alone or in combination with other methods, for the management of atrophic or hypertrophic/keloidal scars. The Web of Science, Scopus, Google Scholar, and Cochrane Library databases were systematically searched until September 1^st, 2020. Thirteen clinical trials were enrolled in the meta-analysis, and 10 more were reviewed for their results. The random effect meta-analysis method was used to assess the effect size of each outcome for each treatment type, and I² was used to calculate the statistical heterogeneity between the studies. Patients treated with PRP experienced an overall response rate of 23%, comparable to the results seen with laser or micro-needling (22% and 23%, respectively) When used alone, moderate improvement was the most frequently observed degree of response with PRP (36%) whereas, when added to laser or micro-needling, most patients experienced marked (33%, 43%, respectively) or excellent (32% and 23%, respectively) results. Concerning the hypertrophic/keloid scars, the only study meeting the required criteria reported a better improvement and fewer adverse effects when PRP was added to the intralesional corticosteroids.

Hence, the study was conducted. A curved slow‐release membrane was produced, and the properties were examined. In addition, the effects of the curcumin slow‐release membrane on cavernous nerve‐injured SD rats were studied. We found that polylactic acid‐glycolic acid‐polyethylene glycol (PLGA‐PEG) can be used as a good carrier material for curcumin, and curcumin‐loaded PLGA‐PEG membranes can effectively rescue the cavernous nerve in SD rats, restore the continuity of the cavernous nerve, and increase the expression of nNOS mRNA and proteins in penile tissue, which can improve the penile erectile function of injured SD rats, reduce the degree of penile tissue fibrosis, and effectively promote penis rehabilitation.
