In a new study led by the University of Michigan, researchers have now created a high-resolution picture of the cells at work inside a key hub of metabolism — the liver — and how individual cell types are reprogrammed in disease.
“That was one question we really wanted to address with this study: Can we have a high-definition picture of each cell type in the liver, what signaling molecules are being released by each of these different cell types and what they are capable of responding to?”
Lin and his colleagues applied this new research tool to obtain a gene expression profile for individual liver cells.
“We wanted to decode what exactly is going on for each cell type during disease,” said Lin, who is also a professor of cell and developmental biology at the U-M Medical School.
Using a mouse model of NASH, the researchers found that the abundance of cells within the liver changed with disease, but so did the properties of each cell type.
