Acute respiratory distress syndrome (ARDS) is a fatal complication of coronavirus disease 2019 (COVID-19). There are a few reports of allogeneic human mesenchymal stem cells (MSCs) as a potential treatment for ARDS. In this phase 1 clinical trial, we present the safety, feasibility, and tolerability of the multiple infusions of high dose MSCs, which originated from the placenta and umbilical cord, in critically ill COVID-19-induced ARDS patients. A total of 11 patients diagnosed with COVID-19-induced ARDS who were admitted to the intensive care units (ICUs) of two hospitals enrolled in this study. The patients were critically ill with severe hypoxemia and required mechanical ventilation. The patients received three intravenous infusions (20
Cell-based therapies are considered as promising strategies for spinal cord regeneration. However, a combinatorial cell therapeutic approach seems more bene cial as it can target various aspects of the injury. Here, we assessed the safety and feasibility of autologous mucosal Olfactory Ensheathing Cell (OEC) and bone marrow Mesenchymal Stem Cell (MSC) co-transplantation in patients with chronic, complete (American Spinal Injury Association (ASIA) classi cation A) Spinal Cord Injury (SCI). Three patients with the traumatic SCI of the thoracic level were enrolled. They received autologous OEC and MSC combination through the lumbar puncture. All adverse events and possible functional outcomes were documented performing pre-and post-operative g
Although numerous replication case-control studies have attempted to determine the association between Factor V Leiden (FVL) 1691G > A mutation and susceptibility to Recurrent pregnancy loss (RPL), there have been confliction among the results of various ethnic groups. To address this limitation, here we implemented first meta-analysis to provide with consistent conclusion of the association between FVL 1691G > A mutation and RPL risk. After a systematic literature search, pooled odds ratio (OR) and their corresponding 95% confidence interval (CI) were used to evaluate the strength of the association. Additionally, meta-regression analyses were performed to find potential source of heterogeneity. In this meta-analysis, 62 studies, c
Using 3D model of injectable scaffolds for cartilage tissue engineering is one of the challenges that should be addressed to avoid invasive surgery for treatment. For this purpose, chondrocytes on Demineralized Bone Matrix (DBM) scaffolds functionalized with glucosamine in 20% polyvinyl alcohol (PVA) as a carrier was applied to the micro-bioreactor in-vitro, then the study was continued on in-vivo stage. Scaffold biocompatibility tests were performed and the mechanical and physicochemical properties were studied showing the fact that DBM was functionalized by Glucosamine, scaffold degradation rate was 53% after 720 hours and swelling ratio was 2.5 times after 16 hours, injectable scaffold demonstrated better mechanical characteristics (P <
Exosome‐based therapy is an emerging novel approach for myocardial infarction (MI) treatment. Exosomes are identified as extracellular vesicles that are produced within multi vesicular bodies in the cells cytosols and then are secreted from the cells. Exosomes are 30–100 nm in diameter that are released from viable cells and are different from other secreted vesicles such as apoptotic bodies and microvesicles in their origin and contents such as RNAs, proteins and nucleic acid. The recent advances in exosomes researches have demonstrated the role of these bio‐nanovesicles in the physiolocal, pathological and molecular aspects of the heart. The results of In vitro and preclinical models have shown that exosmes from different cardiac c
Functional cartilage tissue engineering needs a substantial, easy to handle scaffold with proper mechanical strength to repair defected area in articular cartilage. In this study, we report the development and characterization of demineralized bone matrix (DBM) in with a poly vinyl alcohol (PVA) to have a proper homogenous injectable scaffold. Injectabiliy of the biodegradable scaffolds, degradation rate, swelling ratio compression and tensile mechanical properties, and viability and proliferation of bone marrow mesenchymal stem cells (BM-MSCs) followed by differentiation of them In-vitro and In-vivo seeded within the scaffold were studied. It demonstrated that the PVA 20% could increase significantly (p < 0.05) the biodegradability of
Hematopoietic stem cell transplantation (HSCT) represents a vital curative choice for many disease. However its outcome can be hampered by a variety of transplant associated complications. Hemorrhagic cystitis (HC) considered as one of the major difficulties after HSCT. HC symptoms comprise hematuria, dysuria, burning during urination, urinary frequency, urgency and incontinency, abdominal or suprapubic pain, urinary obstruction, and renal or bladder damage. There are a lot of causes for HC development. BK virus reactivation is one of the major causes of HC after HSCT. There is still no standard and approved treatment protocol for BK virus associated HC (BKV-HC). Treatment of HC is according to the local standard operating procedures, depen
Background Cellular transplantations have promising effects on treating spinal cord injury (SCI) patients. Safety alongside the complementary characteristics of Mesenchymal stem cells (MSC) and Schwann cells (SC) are suggested to be the two of the best candidates in SCI treatment. In this study, we assessed the safety and e cacy of intrathecal co-transplantation of autologous bone marrow MSC and SC in the patients with subacute traumatic complete SCI.Methods Eleven patients with complete SCI (American Spinal Injury Association Impairment Scale (AIS); grade A) were enrolled in this study during the subacute period of injury. The patients received intrathecal autologous combination of MSC and SC and were followed-up for 12 months. We assessed
The function of fibroblast cells in wounded areas results in reconstruction of the extra cellular matrix and consequently resolution of granulation tissue. It is suggested that the use of platelet‐rich plasma can accelerate the healing process in nonhealing or slow‐healing wounds. In this study, a simple and novel method has been used to fabricate an electrospun three‐layered scaffold containing plasma rich in growth factor with the aim of increasing the proliferation and migration of fibroblast cells in vitro. First, plasma rich in growth factor was derived from platelet rich plasma, and then a three‐layered scaffold was fabricated using PLLA nanofibers as the outer layers and plasma rich in growth factor‐containing gelatin fibe
New insights on cellular and molecular aspects of both oligodendrocyte (OL) differentiation and myelin synthesis pathways are potential avenues for developing a cell-based therapy for demyelinating disorders comprising multiple sclerosis. MicroRNAs (miRNA) have broad implications in all aspects of cell biology including OL differentiation. MiR-184 has been identified as one of the most highly enriched miRNAs in oligodendrocyte progenitor cells (OPCs). However, the exact molecular mechanism of miR-184 in OL differentiation is yet to be elucidated. Based on immunochemistry assays, qRT-PCR, and western blotting findings, we hypothesized that overexpression of miR-184 in either neural progenitor cells (NPCs) or embryonic mouse cortex stimulated
Graphene based nanomaterials are promising candidates for cardiac tissue engineering due to the excellent electrical and mechanical properties and the robust surface chemistry. This research was designed to investigate the physicochemical and biological effects of increasing concentration of reduced graphene oxide (rGO) coating on collagen (Col) scaffolds as well as their antibacterial properties. Enhanced GO coating content to 400 μg/ml and its reduction showed improvement of HUVECs viability, however, following reduction of more GO concentration, decreased cell viability was observed. Compared with the Col counterpart, electroactive containing rGO scaffolds upregulated cardiac gene expression involve in electrical coupling (Cx43), musc
