Abstract (original English)

Objectives: Animal studies have demonstrated that mesenchymal stem cell-conditioned medium (MSC-CM) possesses various therapeutic effects, including anti-inflammatory and anti-fibrotic properties. This study investigated the efficacy and safety of administering MSC-CM as a treatment for patients with generalized fatigue. Methods: The MSC-CM used in this study was derived from human adipose tissue and umbilical cord-derived mesenchymal stem cells cultured in a medium free of animal-derived components to avoid the risk of infection. This MSC-CM has recently been shown to possess anti-inflammatory effects and has been reported to be safe for human administration. With the expectation of alleviating fatigue symptoms through its anti-inflammatory effects, it was administered to patients intravenously and by inhalation. Safety and changes in subjective symptoms were evaluated, and blood biomarkers related to inflammation and oxidative stress were measured. Results: In this trial involving 19 patients experiencing fatigue, no serious side effects were observed following MSC-CM administration. Nearly half of the patients reported symptom improvement after a single dose, and some exhibited signs of reduced inflammation. Conclusions: This report presents the first investigation of systemic MSC-CM treatment for generalized fatigue, paving the way for more targeted studies on dosage and tr
