Advancements in the field of CAR-T therapy have brought about a revolution in the treatment of numerous types of cancer in the past ten years. However, despite the remarkable success achieved thus far, certain barriers impede the widespread implementation of this therapy such as intricate manufacturing processes and treatment-associated toxicities. As an alternative, chimeric antigen receptor-engineered natural killer cell (CAR-NK) therapy presents a viable opportunity for a simpler and more cost-effective "off-the-shelf" treatment option, which is likely to result in fewer adverse reactions.

In the medical field, wound healing poses significant challenges due to its complexity and time-consuming nature. Cell-free wound repair, notably the utilization of exosomes (EXOs), has made significant progress in recent years. Urine, saliva, umbilical cord, blood, mesenchymal stem cells and breast milk cells can be used to extract and purify EXOs, which are Nano-sized lipid bilayer vesicles.

Apoptosis may disrupt differentiation of hematopoietic stem cells (HSCs), which can affect aging. Thus, the main goal of this study was to compare the effect of plasma exosomes from young and old people on the expression of Bcl-2-associated X ( and B-cell lymphoma 2 () genes in the HSCs. Plasma samples were acquired from four elderly adults and four younger adults, referring to Blood Transfusion Organization of Tehran-Iran during August 2022- September 2022.

Article Synopsis
  • - The study explored the safety and effectiveness of injecting placental mesenchymal stromal cells-derived extracellular vesicles into knees of patients with osteoarthritis, comparing it to a control group who received saline injections.
  • - In a triple-blind, randomized clinical trial involving 62 knees (31 patients), various measures, including pain and function assessments, were taken before and after the treatment, but no significant improvements were found between the two groups after 2 and 6 months.
  • - The conclusion highlighted that while the injection was safe with no severe reactions observed, it did not lead to any clinical improvement in knee osteoarthritis symptoms or MRI findings.

Mammalian cell cultures in laboratories are performed in static and dynamic methods, and cell growth indices are higher in dynamic mode. In this study, a lab-scale stirred bioreactor using a vibrating disc and a suitable setup has been introduced for dynamic cell culture, which creates proper mixing at low shear stress. 15 experiments have been done by Raji cell in batch mode using Box-Behnken design to quantitatively investigate the effect of mechanical and geometrical factors of this bioreactor on cell culture indices.

Decellularized marine tissues have been regarded as a desirable biomaterial because of their biological risk reduction, less religious constraints, and resemblance to mammalian tissues. The properties of these matrices can be improved by adding cross-linkers. In this study, after decellularization of the of Tilapia and Grass carp fish skin, a comparative study was conducted between them.

Introduction: Wound healing is a major therapeutic concern in regenerative medicine. The current study aimed to investigate the second-degree burn wound treatment in rats using rat adipose- derived stem cells (ADSCs) and manganese nanoparticles (MnO-NPs) in a polycaprolactone/gelatin electrospun nanofiber scaffold.

Methods: After the synthesis of nanoparticles and electrospinning of nanofibers, the SEM analysis, contact angle, mechanical strength, blood compatibility, porosity, swelling, biodegradability, cell viability, and adhesion assays were performed.

  • Crohn's disease perianal fistulae often don't respond well to standard therapies, but mesenchymal stem cell (MSC)-derived exosomes have shown potential as a treatment, being deemed safe in previous studies.
  • A phase II clinical trial was conducted with 23 patients suffering from refractory perianal fistulas, where exosomes were injected directly into the fistula tracts over a period of 6 months.
  • Results indicated that 60% of patients achieved complete fistula closure, and overall, 69.7% of treated fistula tracts showed significant closure, along with some observed improvements in discharge from the tracts.

Osteochondral tissue engineering using layered scaffolds is a promising approach for treating osteochondral defects as an alternative to microfracture procedure, autologous chondrocyte implantation, and cartilage-bone grafting. The team previously investigated the chondrogenesis of mesenchymal stem cells (MSCs) on a polycaprolactone (PCL)/acetylated hyaluronic acid scaffold. The present study first focused on fabricating a novel osteoconductive scaffold utilizing bismuth-nanohydroxyapatite/reduced graphene oxide (Bi-nHAp/rGO) nanocomposite and electrospun PCL.

Objective: Neurological and functional impairments are commonly observed in individuals with spinal cord injury (SCI) due to insufficient regeneration of damaged axons. Exosomes play a crucial role in the paracrine effects of mesenchymal stem cells (MSCs) and have emerged as a promising therapeutic approach for SCI. Thus, this study aimed to evaluate the safety and potential effects of intrathecal administration of allogeneic exosomes derived from human umbilical cord MSCs (HUC-MSCs) in patients with complete subacute SCI.

Greenhouses located at high latitudes and in cloudy areas often experience a low quality and quantity of light, especially during autumn and winter. This low daily light integral (DLI) reduces production rate, quality, and nutritional value of many crops. This study was conducted on Sakhiya RZ F1 tomato plants to evaluate the impact of LED lights on the growth and nutritional value of tomatoes in a greenhouse with low daily light due to cloudy weather.

The limited availability of a healthy donor cornea and the incidence of allograft failure led researchers to seek other corneal substitutes via tissue engineering. Exploring the trend of clinical trials of the cornea with the vision of tissue engineering provides an opportunity to reveal future potential corneal substitutes. The results of this clinical trial are beneficial for future study designs to overcome the limitations of current therapeutic approaches.

Introduction: This study aimed to assess the potential of poly (acrylic acid)/tricalcium phosphate nanoparticles (PAA/triCaPNPs) scaffold in terms of biocompatibility and osteoconductivity properties the in-vivo evaluation as well as to investigate the performance of PAA/triCaPNPs scaffold (with or without exosomes derived from UC-MSCs) for bone regeneration of rat critical-sized defect.

Methods: PAA/triCaPNPs scaffold was made from acrylic acid (AA) monomer, N,N'-methylenebisacrylamide (MBAA), sodium bicarbonate (SBC), and ammonium persulfate (APS) through freeze-drying method. For evaluation, we randomly divided 24 rats into three groups.

Chimeric antigen receptors (CARs) offer a promising new approach for targeting B cell malignancies through the immune system. Despite the proven effectiveness of CAR T cells targeting CD19 and CD22 in hematological malignancies, it is imperative to note that their production remains a highly complex process. Unlike T cells, NK cells eliminate targets in a non-antigen-specific manner while avoiding graft vs.

Sulfur mustard (SM) or mustard gas is a blister chemical agent that causes pulmonary damage by triggering inflammation and oxidative injury. Alterations in microRNA (miR) transcript levels are found in pulmonary diseases and even inflammation. Therefore, we evaluated the expression levels of miR-20a-5p, miR-21-5p, and two target transcripts (transforming growth factor-beta [TGF-β1] and TGF-β receptor 2 [TGFR2]) in lung, serum, and skin samples from patients exposed to SM.
