Abstract (original English)

This review examines the synergistic effects and mechanisms of Traditional Chinese Medicine (TCM) and its extracts on mesenchymal stem cells (MSCs), with a focus on enhancing MSC proliferation, differentiation, and immunomodulation for therapeutic applications. A comprehensive analysis of studies from the past five years was conducted, evaluating interactions between TCM/extracts and MSC types (bone marrow-, adipose-, and umbilical cord-derived MSCs) through molecular pathways (e.g., PI3K/Akt, Wnt/β- catenin, TGF-β/Smad) and microRNA regulation. In vitro, in vivo, and clinical trial data were synthesized. TCM and extracts significantly upregulated osteogenic/adipogenic differentiation in bone marrow mesenchymal stem cells via miR-335-5p/PTEN and Runx2 pathways, enhanced the viability of adipose-derived mesenchymal stem cells under oxidative stress via Sirt1/Akt activation, and improved the immunomodulation of umbilical cord mesenchymal stem cells by increasing anti-inflammatory factors (HGF, PGE2). Combined MSC-TCM therapies accelerated diabetic ulcer healing (via the miR-146A-NF-κB axis), reduced liver fibrosis (via miR-19b-3p), and mitigated stroke/arthritis symptoms. TCM synergizes with MSCs through multipathway crosstalk and miRNA regulation, amplifying therapeutic efficacy in degenerative, inflammatory, and ischemic diseases. Clinical translation requires standardized TCM
