Images of Figures 4, 5 and 6 in this paper showed astonishing similarities with acupuncture meridians and acupuncture points in human. These astonishing similarities support a long time suspicion of mine: acupuncture meridians and acupuncture points may be the hidden ultra-structures formed during embryogenesis.

The earliest illustration of acupuncture meridians were drawn on a silk book dated about 200 B.C. found by archeologists in 1973 in south China. Except the descriptions in ancient medical literatures, the knowledge of the meridians as the sensations of Qi moving along the meridians on the human body has been mainly passed from one generation to another in Chinese history through masters who practice Dao style Qi Gong. Some of those masters were also famous practitioners of the Traditional Chinese Medicine. A population based survey of subjective descriptions of meridians was carried out in China during the 1970s. According to a summary report, 178,533 normal human subjects participated in this nation-wide survey in China, only 500 people (about 0.1%) were reported having various degrees of meridian like sensations under non unified testing methods done by 18 institutions across many regions of China. The low existing rate of this meridian phenomenon makes the study of this phenomenon very difficult. Objective scientific evidence supporting the existence of the meridian has not been provided without controversies and disagreements.

If the results of this work are related to acupuncture meridian and acupuncture points, clonal analysis methodology provides an opportunity to build animal models to study phenomena associated with acupuncture meridian. It would be very valuable to trace the 3D structures of nerve terminals including the sensory and autonomic nerve endings, blood vessels and the locations of mast cells surrounding the origins of the clones. It would also be very valuable to overlay the clones of ectoderm with the clones of other tissue types.
