Does automated morphometry provide accurate and reproducible virtual staging of liver fibrosis in chronic hepatitis C?
The new automated morphometric scores provide reproducible and accurate diagnoses of fibrosis stages via "virtual expert pathologist."
In Drosophila, all of the signalling activity of Hedgehog resides in the amino-terminal portion of the protein, the secretion of which is essential for its function. The range of Hedgehog is limited by the close association of the amino-terminal peptide with the cell surface but can be extended by elevating the level of its expression.
