Visualized regional hypodermic migration channels of interstitial fluid in human beings: are these ancient meridians?
We imaged 6 regional migration channels originating from 6 acupoints on 6 yin meridians of hand and foot by injecting a minimal amount of tracer into acupoints directly in humans. The responses of the subcutaneous specific channels to acupuncture needling are different from those of lymphatic or blood vessels and coincide partially with the characteristics of acupuncture therapeutics, suggesting the existence of meridian-like channels in humans. These findings may contribute to further research on the specific interstitial fluid drainage.
The results imply the existence of a network of reciprocal interactions between normal epithelial and some types of mesenchymal cells mediated by soluble factors that act in a paracrine manner to protect DNA from genotoxic stress.
