Intra-Articular Injection of Human Bone Marrow-Derived Mesenchymal Stem Cells in Knee Osteoarthritis: A Randomized, Double-Blind, Controlled Trial.
Cell Transplant
January 2025
Division of Rheumatology, Department of Internal Medicine, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.
To assess the impact of a single intra-articular (IA) injection of bone marrow-derived mesenchymal stem cells (BM-MSCs) in patients with knee osteoarthritis (OA), a randomized, double-blind, placebo-controlled study was conducted. The study included 24 patients with knee OA who were randomly assigned to receive either a single IA injection of BM-MSCs or normal saline. Changes in the visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Knee Injury and Osteoarthritis Outcome Score (KOOS) after IA injection were assessed at 3, 6, 9, and 12 months.

Neuropathic pain is a debilitating complication following spinal cord injury (SCI). Currently, effective treatments for SCI-induced neuropathic pain are highly lacking. This clinical trial aimed to investigate the efficacy of combined intrathecal injection of Schwann cells (SCs) and bone marrow-derived mesenchymal stem cells (BMSCs) in improving SCI-induced neuropathic pain.

Weintraub Center for Reconstructive Biotechnology, UCLA School of Dentistry, Los Angeles, CA, USA.
Background/purpose: studies are essential for understanding cellular responses, but traditional culture systems often neglect the three-dimensional (3D) structure of real implants, leading to limitations in cellular recruitment and behavior largely governed by gravity. The objective of this study was to pioneer a novel 3D dynamic osteoblastic culture system for assessing the biological capabilities of dental implants in a more clinically and physiologically relevant manner.
Materials And Methods: Rat bone marrow-derived osteoblasts were cultured in a 24-well dish with a vertically positioned dental implant.
Mannose-modified exosomes loaded with MiR-23b-3p target alveolar macrophages to alleviate acute lung injury in Sepsis.

Department of Burn Surgery, the First Affiliated Hospital of Naval Medical University, Shanghai 200433, China. Electronic address:
The anti-inflammatory role of miR-23b-3p (miR-23b) is known in autoimmune diseases like multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. However, its role in sepsis-related acute lung injury (ALI) and its effect on macrophages in ALI remain unexplored. This investigation aimed to evaluate miR-23b's therapeutic potential in macrophages in the context of ALI.

Objective: Aberrant 6-phosphofructo-2kinase/fructose-2,6-bisphoshatase 3 (PFKFB3) expression is tightly correlated with multiple steps of tumorigenesis; however, the pathological significance of PFKFB3 in macrophages in patients with rheumatoid arthritis (RA) remains obscure. In this study, we examined whether PFKFB3 modulates macrophage activation and promotes RA development.
Method: Peripheral blood mononuclear cells (PBMCs) from patients with RA, THP-1 cells, and bone marrow-derived macrophages from conditional PFKFB3-knockout mice were used to investigate the mechanism underlying PFKFB3-induced macrophage regulation of RA.
