Part 1: Defining unproven cellular therapies

Given the potential of cell-based products, including stem/progenitor cells and immune cells, there is a global effort to introduce these therapies into the clinic to correct organ dysfunctions, to treat cancer and to abrogate autoimmune diseases and a wide variety of pathological conditions [1\u20133]. Relatively easy access to these cells, obtained from marrow, adipose, cord blood and other human tissues, provides tremendous opportunity for translational research, particularly for indications with no satisfactory medical solution for patients with \u201cunmet medical needs.\u201d Prenatal and adult stem cells (including induced pluripotent stem cells have significant potential to rebuild tissues and correct dysfunctional organs in human diseases
