Liver Regeneration and New Technical Possibilities by Two-Photon Based Intravital Imaging

One of the outstanding features of the liver is its enormous regeneration capacity. Compared to other solid organs, such as kidney, pancreas, heart or brain, the liver shows a superior capacity to regenerate. Probably, this regeneration capacity has evolved during ‘animal plant warfare’, when plants...
