Professor Jason Jungsik Song's research lab focuses on translational biomedical research with a strong emphasis on regenerative medicine, inflammatory diseases, and novel therapeutic interventions. Key research directions include the molecular mechanisms of mesenchymal cell condensation in cartilage formation, the role of immune and coagulation systems in autoimmune arthritis, and the clinical evaluation of natural agents like honey in managing radiation-induced mucositis and wound healing. The lab integrates in vitro models, preclinical disease models, and clinical data synthesis to bridge basic science discoveries with patient-centered therapies.

Spinal cord stimulation has demonstrated clinical efficacy in randomized control trials for the approved indications. In addition, several open label observational studies on peripheral nerve field stimulation, hybrid leads, dorsal root ganglion stimulation, and high frequency stimulation show some promising results. However, large randomized control trials demonstrating clear clinical benefit are needed to gain evidence based support for their use.
Mesenchymal cell (MC) condensation or the aggregation of MCs precedes chondrocyte differentiation and is required for subsequent cartilage formation during endochondral ossification. In this study, we used micromass cultures of C3H10T1/2 cells as an in vitro model system for studying MC condensation and the events important for this process. Transforming growth factor beta1 (TGF-beta1) served as the initiator of MC condensation in our model system and we were interested in determining whether CT
The immune and coagulation systems are both implicated in the pathogenesis of rheumatoid arthritis (RA). Plasma carboxypeptidase B (CPB), which is activated by the thrombin/thrombomodulin complex, plays a procoagulant role during fibrin clot formation. However, an antiinflammatory role for CPB is suggested by the recent observation that CPB can cleave proinflammatory mediators, such as C5a, bradykinin, and osteopontin. Here, we show that CPB plays a central role in downregulating C5a-mediated in
Recently, 4 separate human controlled trials reported that honey appeared to protect from the effects of radiation-induced oral mucositis formation, a complication of radiation therapy that is responsible for pain and overall reduction in quality of life. In this systematic review and meta-analysis, the authors examined 3 of these controlled trials (n = 120) that met the inclusion and exclusion criteria to determine whether honey had protective effects against radiation-induced oral mucositis. T
Learn how to manage, lead, and succeed . . . the Samsung way. Based on ten years of research and interviews with 80 top executives, the award-winning The Samsung Way is the first definitive guide to the groundbreaking management principles that transformed a lagging electronics company into one of the most successful brands in the world. Combining professional insights from Samsung insiders with practical applications for managers, executives, and CEOs, this powerhouse of a book shows you
The therapeutic use of honey in wound care has been used since ancient times. Honey has been shown to have antibacterial properties in vitro and animal studies have demonstrated accelerated wound healing with the use of honey. In human trials, there is currently not enough strong evidence to fully support the use of honey in wound care; however, use in minor burns and prevention of radiation mucositis appear to be 2 areas where honey shows therapeutic promise.
CMV-DNA copy numbers and concurrent infections are predictors of in-hospital mortality in CMV-infected patients with autoimmune diseases. Therefore, serial measurements of CMV-DNA copy numbers and close observation for signs of other infections are recommended for patients with autoimmune diseases who have concurrent CMV infection.
Ex vivo IFN-γ production is a useful biomarker for assessing disease activity and predicting poor clinical outcomes of SLE.
We aimed to determine the significance of cytoplasmic antinuclear antibody (ANA) patterns using computer-aided immunofluorescence microscopy in patients with autoimmune liver diseases (AILD). ANA staining pattern was identified by treating cultured human epithelial type 2 (HEp-2) cells with the sera of the patients. Medical records of patients with suspected AILD who had positive cytoplasmic ANA patterns between February 2017 and November 2019 were retrospectively reviewed for clinical, laborato
In Asian patients with early RA, T2T improves disease activity and physical function. Setting a pre-defined treatment target in terms of DAS28 is recommended.
Although recent studies have demonstrated a proinflammatory effect of extracellular histones in sepsis <i>via</i> endothelial cytotoxicity, little is known about their contribution to autoimmune arthritis. Therefore, we investigated the role of extracellular histones in autoimmune arthritis and their cytotoxic effect on synoviocytes and macrophages. We measured histones in the synovial fluid of patients with rheumatoid arthritis (RA) and evaluated arthritis severity in a serum-transfer arthritis
The presence of MAS in KFD was associated with adverse clinical outcomes including higher steroid usage and worse hospitalisation outcomes. However, compared to those with AOSD and SLE, patients with MAS and KFD were less likely to require long-term glucocorticoid treatment.
Various subgroups of SpA can be presented with fever as an initial manifestation. Febrile SpA patients demonstrated higher systemic inflammation and a lower chance to visit rheumatology in early stage. When evaluating febrile patients with any clinical features of SpA, clinicians are advised to consider performing SpA-focused evaluation including HLA-B27 or a simple sacroiliac joint radiograph.
