Mesenchymal stem cells (MSCs) and mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) have been regarded as the beneficial and available tools to treat various hereditary, multifactorial, acute, and chronic diseases. Mesenchymal stem cells can be extracted from numerous sources for clinical purposes while oral cavity-derived mesenchymal stem cells seem to be more effective in neuroregeneration than other sources due to their similar embryonic origins to neuronal tissues. In various studies and different neurodegenerative diseases (NDs), oral cavity mesenchymal stem cells have been applied to prove their promising capacities in disease improvement. Moreover, oral cavity mesenchymal stem cells' secretion is regarded as a novel and practical approach to neuroregeneration; hence, extracellular vesicles (EVs), especially exosomes, may provide promising results to improve CNS defects. This review article focuses on how oral cavity-derived stem cells and their extracellular vesicles can improve neurodegenerative conditions and tries to show which molecules are involved in the recovery process.

Engineering functional exosomes represents a cutting-edge approach in biomedicine, holding the promise to transform targeted therapy. However, challenges such as achieving consistent modification and scalability have limited their wider adoption. Herein, we introduce a universal and effective strategy for engineering multifunctional exosomes through cell fusion.

Background: Sjögren's syndrome (SS) is a chronic autoimmune disease delineated by excessive lymphocyte infiltration to the lacrimal or salivary glands, leading to dry eye and dry mouth. Exosomes secreted from mesenchymal stem cells (MSC) are known to have anti-inflammatory and tissue regeneration abilities. This study endeavored to demonstrate the effect of MSC-derived exosomes on the clinical parameter of dry eyes and associated pathology in SS mouse model.

To compare the efficacy of using bone marrow mesenchymal stem cell (BM-MSC) exosomes and injectable platelet rich fibrin (i-PRF) on the submandibular salivary glands (SMGs) of aged albino rats in restoring salivary gland structure and function. A total of 40 healthy male albino rats were used, two for obtaining the BM-MSCs, 10 for i-PRF preparation and seven adult rats (6-8 months old) represented the control group (Group 1). The remaining 21 rats were aged (18-20 months old) and divided into three groups of seven rats each; (Group 2): received no treatment, (Group 3): each rat received a single intraglandular injection of BM-MSC exosomes (50 μg/kg/dose suspended in 0.

Introduction: Hematopoietic stem cell transplantation (HSCT) is a promising treatment option for hematological malignancies. Despite its curative potential, it faces clinical challenges, including relapse and graft-versus-host disease (GVHD). Systemic toxicity due to chemotherapy is a significant problem in patients with hematological malignancies.

In the current in vitro experiment, we fabricated and characterized placenta/platelet-rich plasma (PL/Pt) composite scaffolds and evaluated their effect on differentiating adipose stem cells (ASCs) into insulin-producing cells (IPCs) in vitro. The human placenta (PL) was decellularized (dPL), characterized, and digested in pepsin. PRP was extracted using a two-step centrifugation process and then freeze-dried.
