Until day 14 post-transplantation, the growth of the stem/progenitor cells was faster than the mature hepatocytes, but after two weeks most of the stem/progenitor cells had died. However, the mature hepatocytes continued to survive and proliferate one year after their implantation.
The study is published in Cell Transplantation (21:1), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/."Cell-based therapies as an alternative to liver transplantation to treat liver disease have shown promise," said study corresponding author Dr. Toshihiro Mitaka of the Cancer Research Institute of the Sapporo Medical University School of Medicine, Sapporo, Japan. "However, the repopulation efficiency of two candidate cell sources - hepatic progenitor/stem cells and mature hepatocytes - had not been comprehensively assessed and questions concerning the efficiency of each needed to be resolved."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
