PPS has been classified as a disease-modifying osteoarthritic drug (DMOAD) and many studies have demonstrated its positive attributes in the countering of degenerative changes occurring in cartilaginous tissues during the development of osteoarthritis (OA). Degenerative changes in the IVD also involve inflammatory cytokines, degradative proteases, and cell signaling pathways similar to those operative in the development of OA in articular cartilage. PPS acts as a heparan sulfate (HS) mimetic to effect its beneficial effects in cartilage. The IVD contains small cell membrane HS proteoglycans (HSPGs) such as syndecan, and glypican and a large multifunctional HS/chondroitin sulfate (CS) hybrid proteoglycan (HSPG2/perlecan), that have important matrix-stabilizing properties and sequester, control, and present growth factors from the FGF, VEGF, PDGF, and BMP families to cellular receptors to promote cell proliferation, differentiation, and matrix synthesis. HSPG2 also has chondrogenic properties and stimulates the synthesis of extracellular matrix (ECM) components and expansion of cartilaginous rudiments, and has roles in matrix stabilization and repair. Perlecan is a perinuclear and nuclear proteoglycan (PG) in IVD cells with roles in chromatin organization and control of transcription factor activity, immunolocalizes to stem cell niches in cartilage, promotes escape of stem cells from quiescent recycling, differentiation and attainment of pluripotency and migratory properties. These participate in tissue development and morphogenesis, ECM remodeling and repair. PPS also localizes in the nucleus of stromal stem cells, promotes development of chondroprogenitor cell lineages, ECM synthesis and repair and discal repair by resident disc cells. The availability of recombinant perlecan and PPS offers new opportunities in repair biology. These multifunctional agents offer welcome new developments in repair strategies for the IVD.</p>","PeriodicalId":21934,"journal":{"name":"Stem cells and development","volume":" ","pages":"406-430"},"PeriodicalIF":4.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39876918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Essential to tissue homeostasis, disease pathogenesis, and therapeutic responses are the stratified organization of cartilage and cross talk at the osteochondral junction. Animal models may capture some of these features, but to establish clinically consistent therapeutics, there remains a need for high-fidelity models of OA that meet all the above requirements in a human patient-specific manner. In vitro bioengineered cartilage-bone tissue models could be developed to recapitulate physiological interactions with human cells and disease-initiating factors. In this study, we highlight human induced pluripotent stem cells (hiPSCs) as the advantageous cell source for these models and review approaches for chondrogenic fate specification from hiPSCs. To achieve native-like stratified cartilage organization with cartilage-bone interactions, spatiotemporal cues mimicking development can be delivered to engineered tissues by patterning of the cells, scaffold, and environment. Once healthy and native-like cartilage-bone tissues are established, an OA-like state can be induced through cytokine challenge or injurious loading. Bioengineered cartilage-bone tissues fall short of recapitulating the full complexity of native tissues, but have demonstrated utility in elucidating some mechanisms of OA progression and enabled screening of candidate therapeutics in patient-specific models.

The biologic augmentation by Osteo Core Plasty™ is a new treatment modality showing promising results reducing pain with the aim to stop the progression of the disease. The purpose of this prospective study is to report the clinical outcomes and safety of Osteo Core Plasty for the treatment of symptomatic BMLs in the knee. Fifteen patients with symptomatic BMLs of the knee treated with the Osteo Core Plasty technique were included and followed prospectively for a minimum of 12 months.

All clinical scores except Tegner and Marx score showed an overall statistically significant improvement through the entire follow-up (<i>P</i> < 0.05) and a significant improvement (<i>P</i> < 0.05) between each follow-up period (T₀ vs. T₁; T₀ vs. T₂; T₁ vs. T₂). No complications were reported. These preliminary results confirm that biological subchondral bone augmentation by Osteo Core Plasty technique is a safe and effective minimally invasive treatment option for symptomatic BMLs in the knee at 1-year follow-up.

Therefore, the objective of this study was to investigate the ability of PDLSC CMs and MFG-E8 to reduce the inflammatory effects of impact injury on porcine talar articular cartilage (AC) and IL-1β on chondrocytes, respectively. Stem cells were isolated from human periodontal ligaments. The MFG-E8 content in CM collected at 5% and 20% oxygen was measured by ELISA assay and compared across subcultures and donors. AC samples were divided into three groups: control, impact, and impact+CM. Chondrocytes were isolated from pig knees and were divided into three groups: control, IL-1β, and IL-1β+MFG-E8. Gene expression data were analyzed by reverse transcription-polymerase chain reaction. It was found that impact load and IL-1β treatment upregulated IL-1β, TNF-α, ADAMTS-4, and ADAMTS-5 gene expression in AC and chondrocytes, respectively. PDLSCs-CM prevented the upregulation of all four genes due to impact, whereas MFG-E8 prevented upregulation of IL-1β, ADAMTS-4, and ADAMTS-5 in chondrocytes, but it did not prevent TNF-α upregulation. There were no significant differences in MFG-E8 content in CM among oxygen levels, passage numbers, or donors.

At present, the methodological quality and risk of bias (RoB) of SRs/MAs on stem cell therapy for the treatment of knee osteoarthritis (KOA) has been poorly investigated. This study aims to strictly evaluate the methodological quality and RoB in SRs/MAs of stem cell therapy for KOA. Four electronic databases (PubMed, Embase, Cochrane Library, and Web of Science databases) were searched, from inception to October 5, 2021. SRs/MAs involving randomized control trials or cohort studies on stem cell therapy for the treatment of KOA were included. The methodological quality and RoB were assessed using AMSTAR 2 and ROBIS tool, respectively. In total, 22 SRs/MAs were included. According to the results obtained by AMSTAR 2 tool, all SRs/MAs were rated as \"Critically low.\" Main methodological weaknesses were as follows: up to 81.82% did not meet protocol registration requirements, only 13.64% provided a list of excluded studies and justification, and 13.64% investigated and discussed the publication bias. ROBIS-based RoB assessment showed that all the SRs/MAs were rated as \"High.\" Besides, the lack of following the implementation of the PRISMA reporting guideline seems to reduce the methodological quality of the studies. The overall methodological quality of the SRs/MAs concerning the application of stem cell therapy in treating KOA is \"Critically low,\" while the RoB is high. It is difficult to provide effective evidence for the formulation of guidelines for KOA treatment. We suggest that the relevant methodological quality assessment should be carried out in the future before the SRs/MAs are used as clinical evidence.

We characterized these cells, mainly focusing on their stemness, multipotency, and neuronal differentiation activities. Spinal cord injury was produced using forceps in adult mice. On day 3 after spinal cord injury, samples were obtained from the injured areas. Spinal cord sections were subjected to histological analyses. Cells were isolated and assessed for proliferative activities, immunohistochemistry, RT-PCR, FACS, and microarray analysis. Although nerve cell morphology was disrupted within the injured spinal cord, our histological observations revealed the presence of cells expressing stem cells, such as nestin and Sox2 in these areas. In addition, cells extracted from injured areas exhibited high proliferative abilities. These cells also expressed markers of both neural stem cells (e.g., nestin, Sox2) and multipotent stem cells (e.g., Sox2, c-myc, Klf4). They differentiated into adipocytes, osteocytes and chondrocytes, as well as neuronal cells. Microarray analysis further identified similar properties between spinal cord (SC)-derived iSCs and B-iSCs. However, SC-iSCs revealed specific genes related to the regulation of stemness and neurogenesis. We identified similar features related to multipotency in SC-iSCs compared to B-iSCs, including neuronal differentiation potential. Although the differences between SC-iSCs and B-iSCs remain largely undetermined, the present study shows that iSCs can develop even after non-ischemic injuries such as trauma.

Release of interleukin-1β (IL-1β), interleukin-10 (IL-10), transforming growth factor beta (TGF-β), vascular endothelial growth factor (VEGF), and platelet derived growth factor (PDGF-BB), as well as fibrinogen degradation, were measured from ePL gel with and without equine bone marrow derived MSCs and compared to MSCs in monolayer. MSC proliferation and viability within the gel were assessed up to 14 days. Compared to monolayer MSC cultures, significantly higher concentrations of IL-1β, IL-10, and TGF-β were measured from supernatants collected from ePL gel containing MSCs at various time points. Significantly lower concentrations of PDGF-BB were measured in the supernatant when MSCs were incorporated in ePL gel while VEGF tended to be increased compared to MSCs in monolayer. Incorporation in ePL gel for up to 14 days did not appear to affect viability and proliferation rates of MSCs as these were found to be similar to those measured in monolayer cell culture. ePL gel may have the potential to serve as bio-scaffold for MSC delivery since it appears to support the proliferation and viability of MSCs for up to 14 days.","PeriodicalId":21934,"journal":{"name":"Stem cells and development","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45623926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
