This paper explains generation

development and key function of germ line stem cell

embryonic stem cell and tissue stem cell based on Chinese medicine theory. According to the connotation of "primordial Qi"and "Qi of Zang-fu viscera"

the authors propose the modern medicine essence of "primordial Qi"and "Qi of Zang-fu viscera"in Chinese medicine. Primordial Qi mainly embodies "the organic collection of all cells basic function and their relationship of the organism". While "Qi of Zang-fu viscera"mainly embodies the basic function and some special function of all cells that made up Zang-fu

as well as the organic collection of the relationship among the cells. Based on scientific hypothesis above

this paper reveals modern medicine mechanism of kidney essence transforming and generating primordial Qi and Qi of Zang-fu viscera and discusses the mechanism of disorder of kidney essence transforming and generating primordial Qi and Qi of Zang-fu viscera leading to senescence and senile diseases

as well as the relating mechanism of herbs regulating and controlling kidney essence transforming and generating primordial Qi and Qi of Zang-fu viscera by acting on cell signal transduction molecules.
