“引经理论”为中医基础理论的重要内容与“归经理论”同源发展。骨髓间充质干细胞（bone mesenchymal stem cells，BMSCs）广泛分布于骨髓及各种结缔组织中，具有极强的多向分化、自我复制与自我更新能力。基质细胞衍生因子-1（stromal cell-derived factor-1，SDF-1）/CXC型趋化因子受体4（C-X-C motif chemokine receptor 4，CXCR4）信号通路为目前学界公认的影响BMSCs归巢及分化的热点通路。基于SDF-1/CXCR4信号通路，以BMSCs归巢及分化为切入点，将中医“引经理论”与细胞靶向迁移学说相结合、使宏观中医理论具体化，进而从分子生物学角度深入探讨中医“引经理论”的科学性与可行性，为引经药物靶向干预BMSCs的临床应用提供充分的理论依据。

Meridian guide theory is an important element of the basic theory of traditional Chinese medicine (TCM), which is homologous to the theory of attribution of meridians. Bone marrow mesenchymal stem cells (BMSCs) are widely distributed in bone marrow and various connective tissues, and have strong multi-directional differentiation, self-replication and self-renewal abilities, and the SDF-1/CXCR4 signaling pathway is currently recognised as a hotspot signaling pathway that affects the homing and differentiation of BMSCs. Based on the SDF-1/CXCR4 signaling pathway, this paper takes BMSCs homing and differentiation as an entry point, and combines the TCM meridian guide theory with cell-targeted migration theory to make the macroscopic TCM theory concrete, and then discusses the scientific validity and feasibility of TCM meridian guide theory in depth from the perspective of molecular biology. We also discussed the scientific validity and feasibility of the TCM meridian guide theory from the perspective of molecular biology, and provided sufficient theoretical basis for the application of meridian-inducing drug-targeting intervention in BMSCs.
