Automated assessment of Ki‐67 proliferation index in neuroendocrine tumors by deep learning

Acta Pathologica, Microbiologica et Immunologica Scandinavica (APMIS), 2021
The Ki‐67 proliferation index (PI) is a prognostic factor in neuroendocrine tumors (NETs) and defines tumor grade. Analysis of Ki‐67 PI requires calculation of Ki‐67‐positive and Ki‐67‐negative tumor cells, which is highly subjective.

Ki‐67 labeling in postmitotic cells defines different Ki‐67 pathways within the 2c compartment [PDF]

Cytometry, 1991
AbstractSimultaneous quantification of DNA and Ki‐67 proliferation‐associated antigen was performed using fluorescence image cytometry. In the MCF‐7 cell line, the Ki‐67 antigen content increases during the cell cycle, and its intranuclear distribution pattern varies.
