Abstract:The epidemiological and experimental evidence suggests that diabetes can be an independent risk factor for osteoarthritis. The osteoarthritis-like cartilage damage has been shown in streptozotocin-induced diabetic mice. The therapeutic effects of human skeletal muscle-derived progenitor cells (HSMPCs) on diabetic osteoarthritis still remain unclear. Here, we investigated the therapeutic potential of HSMPCs on diabetic knee osteoarthritis. The in vitro chondrogenic ability of HSMPCs was determined by pellet cul… Show more
“…Our findings corroborate several studies in mice in which loss of chondrocytes and cartilage tissue in the joints of diabetic animals were reported. (14,15,46,47) However, the severity of OA in our study was much less preeminent than in other studies. This difference in OA severity and responses in the T1DM animals may be explained by several factors such as the use of different animal strains, the age of the animal, the duration of the experiment, type of diabetic model used, and the type of histological assessment of OA.…”

“…Patients with diabetes often have vascular and neurological disorders, which can affect the normal metabolism and repair capacity of the joints, thereby promoting the development of fibrosis. 28 A preoperative WOMAC stiffness score of 44 or less was a significant predictor of increased stiffness symptoms 1 year after HTO (AUC 0.75, p<.001). WOMAC stiffness score can serve as a screening tool to assess the high-risk population for knee joint stiffness.…”

Background Symptoms of knee stiffness after open wedge high tibial osteotomy (OW-HTO) can significantly affect surgical effectiveness, but no studies have reported risk factors for knee stiffness after OW-HTO. Methods Patients treated with OW-HTO for the first time between 2018 and 2021 were included. Data were collected on patient demographics, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Short Form (SF) 12 scores, hip-knee-ankle angle (HKA) and patient satisfaction before and after surgery. Patients with worse WOMAC stiffness scores at 1 year were defined as the 'increased stiffness' group and the other cohort as the 'non-stiffness' group. The primary outcome of the study was to compare postoperative knee function scores (WOMAC and SF-12), HKA and patient satisfaction rate between the two groups. The secondary outcome was the use of logistic regression to analyze independent predictors of increased postoperative stiffness symptoms. Results At 1 year postoperatively, 95 (11.3%) patients had a significant increase in stiffness. Patients had significantly ( p < .001) less improvement in pain, function, and total WOMAC scores, and SF-12 score than those in the non-stiffness group ( n = 745). However, the differences in WOMAC and SF-12 scores in increased stiffness group at 1 year post-operatively were statistically significant ( p < .001) compared to the non-stiffness group. There was no statistically significant difference in HKA in the increased stiffness group (172.9° ± 2.3°) compared to non-stiffness group (173.4° ± 2.6°) at 1 year postoperatively ( p = .068). Patient satisfaction was significantly lower in the increased stiffness group ( p < .001). Logistic regression analysis showed that diabetes (odds ratio (OR) 1.809, p = .034) and preoperative WOMAC stiffness score of 44 or less (OR 4.255 p < .001) were predictors of increased stiffness. Conclusions Patients with increased stiffness after OW-HTO had worse functional outcomes and lower patient satisfaction rates and patients at risk of being in this group should be informed pre-operatively.
“…MDSPCs are characterized by multipotency, long-term proliferation, and self-renewal capacities [31,32]. The most important properties of MDSPCs include their resistance to oxidative and inflammatory stress, induction of neovascularization, and stimulation of regeneration of various tissues, such as bone, cartilage, peripheral nerve, and skeletal muscles [33][34][35][36][37][38][39]. MDSPCs have also demonstrated the ability to extend life and health span in accelerated-aging animal models through paracrine/endocrine mechanisms of action [40].…”
Background and Objectives: To date, the therapeutic potential of skeletal muscle-derived stem/progenitor cells (MDSPCs) for acute kidney injury (AKI) has only been evaluated by our research group. We aimed to compare MDSPCs with bone marrow mesenchymal stem cells (BM-MSCs) and evaluate their feasibility for the treatment of AKI. Materials and Methods: Rats were randomly assigned to four study groups: control, GM (gentamicin) group, GM+MDSPCs, and GM+BM-MSCs. AKI was induced by gentamicin (80 mg/kg/day; i.p.) for 7 consecutive days. MDSPCs and BM-MSCs were injected 24 h after the last gentamicin injection. Kidney parameters were determined on days 0, 8, 14, 21, and 35. Results: MDSPCs and BM-MSCs accelerated functional kidney recovery, as reflected by significantly lower serum creatinine levels and renal injury score, higher urinary creatinine and creatinine clearance levels (p < 0.05), lower TUNEL-positive cell number, and decreased KIM-1 and NGAL secretion in comparison to the non-treated AKI group. There was no significant difference in any parameters between the MDSPCs and BM-MSCs groups (p > 0.05). Conclusions: MDSPCs and BM-MSCs can migrate and incorporate into injured renal tissue, resulting in a beneficial impact on functional and morphological kidney recovery, which is likely mediated by the secretion of paracrine factors and an anti-apoptotic effect. MDSPCs were found to be non-inferior to BM-MSCs and therefore can be considered as a potential candidate strategy for the treatment of AKI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
