Ectopic fat deposits include adipocyte infiltration into the parenchyma as well as fat droplet formation within tissue cells other than adipocytes. In the liver, hepatocytes accumulate fat in intracellular lipid droplets, whereas, in the pancreas, lipids are mainly stored in adipocytes which infiltrate ...
Why do cells have two nuclei? Multiple Nuclei in Human Cells Liver cells often have two nuclei so they can more efficiently do all these jobs. Having two nuclei is like having two sets of blueprints, sothe cells can build two proteins at the same time. ...
How is liver cancer treated?Surgery may be done to remove tumors that are small and have not spread to other parts of the body. Medicines , such as chemotherapy, may be used to reduce the size of the tumor. Medicines may also be given to prevent cancer cells from growing or spreading....
give cancer cells a competitive advantage over the host. A surge of research efforts has attempted to understand the basis of this advantage and seek ways of exploiting it therapeutically. Here, we review key findings and place these in the context of a mathematical framework. Looking ahead, we...
