regenerative capacity of mammals is limited and can rarely regenerate a specific organ or tissue fully. due to these limitations, regenerative medicine seeks efficient and safe cell sources for regeneration of damaged tissues and organs or treatment for incurable diseases. human embryonic stem cells (hescs) hold two important properties called self renewal and pluripotency. however, the use of ...

within a single tumor clone, cells have significantly different abilities to proliferate and form new tumors. this has led to the hypothesis that most cells in a cancer have a limited ability to divide and only a small subset of distinct cells, the cancer stem cells (cscs), has the capacity to self-renew and form new tumors . it has been proposed that the development of tumors is based exclusiv...
