A research group headed by Takashi Tsuji of the Tissue Engineering Research Center has developed a new cell manipulation technology whereby organ germs are artificially recombined from single cells. This technology has the potential for application to artificial "tooth regeneration" and "hair regeneration".

The response to drug combinations critically depends on how their biological targets are connected, according to a study published online in Molecular Systems Biology this week. Understanding how multi-drug combinations work is vital in medicine, in order to rationalize their use and discover novel targets.
