Figure 1.

Therapeutic potentials of cell therapy are shown. 1. Neurorestoration, either by cell replacement or neural circuitry repair, is achieved by cell transplantation. 2. The activation of endogenous neurogenesis, as well as angiogenesis and vasculogenesis, provides a reservoir of proliferating new cells. 3. Systemic/local immunomodulation is one of the key factors on cell therapy. 4. Stem cell–based tools serve as drug discovery and screening of disease pathology, broadly representing another application of cell therapy
