It is hypothesised that hypoxic conditioning of mesenchymal stem cells (MSC) through the activation of hypoxia-inducible factor-1 alpha (HIF-1α), may enhance tendon repair process by promoting cellular proliferation and tenogenic differentiation. To demonstrate this, a study using roxadustat, a specific hypoxia mimetic mediator and HIF-1α inducer was conducted on adipose-derived mesenchymal stromal cells (AD-MSCs). Cellular morphology, proliferation rates, tenogenic protein and gene expression levels in untreated AD-MSCs (Group 1), roxadustat pre-conditioned AD-MSCs (Group 2), AD-MSCs subjected to CAY10585 (Group 3), roxadustat pre-conditioned AD-MSCs with CAY10585 (Group 4) and untreated primary tenocytes (Group 5) were evaluated. MSCs pre-conditioned with 12.5µM roxadustat for 24 hours showed the highest expression of HIF-1α without affecting the proliferation rates of AD-MSCs. However, significant reduction of HIF-1α levels was observed when the cells were treated with 3.5µM CAY10585. Roxadustat significantly up-regulated collagen I and III expressions by 6.6 and 6.3-fold respectively. HIF-1α promoted <i>Scleraxis</i>, <i>Tenascin-C</i> and <i>Collagen III</i> expressions, resulting in an increase of 6, 7, and 3 folds respectively.

Many factors have been suggested to be associated with depression, one of which is low testosterone in men. The serotonin reuptake inhibitor fluoxetine (FLU), used to treat depression, has been reported to potentially have detrimental effects on spermatogenesis in rats after long-term use. The multimodal antidepressant vortioxetine (VTX) offers new promise for the treatment of depression. The chronic unpredictable mild stress (CUMS) model is widely known as an experimental paradigm used to study depression-like behaviors in rodents. Stress leads to various neurochemical and immune changes, affecting multiple organs. Our study aims to examine the histopathological findings in testicular tissue induced by CUMS and the immunohistochemical expression of Cas-8, IL-6, and RANKL using a depression model in rats. Rats were split into 4 groups of 7 animals each at random. Group 1 (control) did not experience any stress. Group 2 (CUMS) was exposed to chronic, unpredictable mild stress using a specific procedure. Group 3 (CUMS+VTX) and Group 4 (CUMS+FLU) underwent CUMS and received intraperitoneal drug treatment at a dose of 10 mg/kg during the final three weeks of the study. The rat testicles collected during necropsy were evaluated histopathologically and immunohistochemically for Cas-8, IL-6, and RANKL expressions using a light microscope. In Group 1, histological analysis showed normal tissue architecture in the testicles and epididymis. In Group 2, there was significant depletion of spermatozoa in the seminiferous tubules and empty tubules in the epididymis. In Groups 3 and 4, FLU and VTX treatment led to improvements in the testicles. Cas-8, RANKL, and IL-6 immunohistochemistry revealed increased expression in Group 2, primarily in interstitial cells. In Groups 1, 3, and 4, no or very slight expression of these markers was observed. The results of this study showed that sperm production in the testes is negatively affected in CUMS-induced depression and that Cas-8, IL-6, and RANKL expression is increased, particularly in interstitial cells.

Short-term immobilization or non-weightbearing after ACL reconstruction further promotes MAT accumulation. However, it is unclear if combining immobilization and non-weightbearing synergistically promotes MAT accumulation. Additionally, it is unknown whether MAT increase induced by immobilization or non-weightbearing can be reversed through remobilization or reloading. We aimed to address these questions. ACL-reconstructed rats were divided into four groups: no intervention, immobilization, non-weightbearing, or immobilization plus non-weightbearing. Immobilization and non-weightbearing were applied for 2 weeks, after which all rats were allowed to move unrestricted. Intact rats were used as controls. The marrow adiposity and trabecular bone in the proximal tibia were histologically assessed at 2-, 4-, and 12-weeks post-surgery. ACL reconstruction induced MAT accumulation and trabecular bone loss accompanied by increased osteoclastogenesis. Two weeks of immobilization and non-weightbearing after ACL reconstruction individually promoted MAT accumulation, but the combined use of these interventions had a similar impact on MAT accumulation as either of each intervention. Importantly, the increased MAT induced by immobilization or non-weightbearing did not reverse even after remobilization or reloading. Neither immobilization, non-weightbearing, nor both conditions combined after ACL reconstruction further decreased trabecular bone compared to no intervention. These findings suggest no synergistic effect of immobilization and non-weightbearing on MAT accumulation, and MAT accumulation induced by 2 weeks of both immobilization or non-weightbearing did not decrease even after at least 10 weeks of remobilization or reloading. MAT accumulation due to both immobilization and non-weightbearing did not have negative effects on trabecular bone.</p>","PeriodicalId":8970,"journal":{"name":"Biotechnic & Histochemistry","volume":" ","pages":"72-82"},"PeriodicalIF":1.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143498790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
