报告简介：  

Longitudinal non-vascular transport pathways originating from an acupuncture point of humans were visualized by MRI. These longitudinal pathways constitute two types of pathways: a cutaneous transport pathway and a perivascular transport pathways. However, their anatomical and histological structures remain unclear. Recently, we explored these specific pathways in human amputee subjects and testified that both the cutaneous and perivascular pathways are composed of an oriented fibrous connective tissue. The intrinsic architecture of those fibrous connective tissues is a three-dimensional meshwork of longitudinally running and interconnected fibril bundles embedded in tissue gel. Between each solid fibril bundle and its surrounding biological hydrogel, an interfacial zone would form physically and fluid can flow, exhibiting a long-distance macroscopic fluid transportation. Through the interfacial zones of these fibrous pathways, named “a biotic interfacial transport pathway (BIFT pathway)”, it is likely in animals that fluids within fibrous matrix in any tissues or organs are not fixed within “tissue gel” but driven towards designed destinations via various as yet unidentified physical mechanisms. The rheology of fluid in the interstitial spaces of skin and perivascular spaces or even other fibrous tissues should be reevaluated in terms of considering fluid transport through the interfacial zones within the gel-like fibrous connective tissues. Most importantly, fluid transport mechanisms through the oriented fibrous connective tissues require further research attentions in fields of an interdisciplinary science.
