stem cells are a kind of pluripotent cells with self-replication and multidirectional differentiation potential. they are the seed cells of human body. they are called "universal cells" by medical circles. stem cells provide a new way to effectively repair the damage of important human tissues and organs and cure cardiovascular diseases, metabolic diseases, nervous system diseases, blood system diseases, autoimmune diseases and other important diseases. with the development of stem cell and tissue engineering, regenerative medicine with stem cell therapy as its core is leading a far-reaching medical revolution.
studies on testicular teratomas in several inbred strains of mice have shown that they originate from embryonic germ cells (eg cells). this work establishes that embryonic carcino-ma cells (ec cells) are stem cells.
