The present invention is directed toward a method for obtaining from whole liver or a resection thereof a population of cells comprising viable, functional liver cells enriched in hepatocytes and hepatocyte stemprogenitor cells, compositions thereof, and uses therefore. The acceleration component contains ultrafine calcium hydroxide having a high specific surface and low grain size. Thereby, the resource information at the resource managing function can be kept updated at reduced signaling load and fast response times due to the fact that resource information is requested only from predetermined areas and at times of change. or less at which no popping phenomenon happens, for removing the hardened layer, and a second step for conducting an ashing process at a second temperature e. A protective layer may be formed so as to cover the second electrode.
