Core Tip

Core tip: Dental pulp-origin mesenchymal stem cells have a remarkable potential for regenerative medicine in both differentiation and proliferation capacity. Dental pulp cell banks are currently under operation in several institutions in Japan, as they can be obtained easily and less invasively in the personal growth process. Recent findings that they can differentiate into hepatocytes suggest that they can be applied to refractory liver diseases as either auto or allogenic cell therapies. These hepatocytes can be used as tailor-made components for a bioartificial liver or liver-on-a-chip to screen for drug toxicities in preparation for future use.
