Experimental Biological Research on Stem Cells in Fascia Tissue
Yinghua Ou,Jingxing Dai,Rong-mei Qu 사단법인약침학회 2013 Journal of Acupuncture & Meridian Studies Vol.6 No.3
The fascia tissue, derived from the mesoderm, is distributed in all parts of the human body. It consists of connective tissues and stem cells. The fascia tissue is also believed to be a functional system, like the digestive system, in the human body, controlling self-inspection, self-maintenance, support, and storage. In addition, much of the research relevant to fascia tissue has focused on adipose-derived stem cells (ADSCs), which mainly exist in adipose tissues. The aim of this review is to summarize the current research on ADSCs, including a brief introduction of their biological characteristics, the isolation and expansion methods, a conclusion on their multidifferentiation potential, new clinical applications, and the therapeutic strategies for treating tumors.
Discovery of Endothelium and Mesenchymal Properties of Primo Vessels in the Mesentery

<P>Recent evidences demonstrated that endothelial-to-mesenchymal transition (EndMT) has a crucial role in cancer and is recognized as a unique source of cancer-associated fibroblasts (CAFs). Primo vascular system (PVS) is a new circulatory system which may play an important role in cancer metastasis and regeneration. In the current study, we applied previously established time-saving method to identify primo vessels and further investigated the immunocytochemical properties of primo vessels. Both primo vessels and primary primo vessel cells in the mesentery expressed endothelial markers and fibroblast markers. Double-labeling experiments demonstrated that endothelial and fibroblast markers are coexpressed in primo vessels. In addition, under the stimulation of TGF-<I>β</I>1 <I>in vitro,</I> primary primo vessel cells differentiated into fibroblasts. Therefore, we found that primo vessels in the mesentery had a transitional structure between endothelium and mesenchymal. This is a new finding of EndMT in normal postnatal animals.</P>

<P>Gastric cancer is the fourth commonest cancer in the world and the second leading cause of cancer-related death. Investigation of gastric cancer metastasis is one of the hottest and major focuses in cancer research. Growing evidence manifested that primo vascular system (PVS) is a new kind of circulatory system beyond vascular and lymphatic system. Previous researches revealed that PVS is a specific tissue between endothelium and mesenchyme and is involved in cancer, especially in tumor metastasis and regeneration. In current study, we investigated the role of primo vessels in gastric cancer metastasis and its possible relationship to vascular vessels formation. Our results indicated that primo vessels were involved in gastric cancer metastasis. We observed blood vessel-mediated metastasis, primo vessel-mediated metastasis, and an intermediate state between them. We deduced that primo vessels may be precursors of blood vessels. These results possibly provided a thoroughly new theoretic development in cancer metastasis.</P>
Putative Primo-vascular System in Mesentery of Rats

Primo-vessels have been observed in the rat abdominal cavity as floating threadlike structures on and not adhering to fascia-wrapped internal organs. To date their presence, locations, and lengths have been irregular and unpredictable, and their identification not regularly repeatable, thus they have remained a nagging enigma in primo-vascular system research for several years. In this work, locations were found where primo-vessels were regularly present and observed repeatedly. These vessels were not floating or freely movable but lay in a regular position in the mesentery in the abdominal cavity of the rat, being observed between the cecum and small intestine and between the colon and mesentery root. The difference between a lymph vessel and a primo-vessel is described in anatomical and histological aspects. In addition, trypan blue was found to enter primo-vessels through the surrounding membranes and filled spaces between fibers comprising the primovessels. It is conjectured that the previously observed floating primo-vessels had anomalously and irregularly emerged, for some unknown physiological reasons,from primo-vessels normally located in the fascia-like mesentery.
