A staining process can measure the percentage of tumor cells that are positive for Ki-67. More positive cells hasten in dividing and forming new cells. Proliferation index was measured by the percentage of cells staining for Ki-67.

    At baseline

  • Ki-67 Protein Proliferation Index

    The Ki-67 protein is a cellular marker for proliferation. Ki-67 is a protein in cells that increases as cells prepare to divide into new cells. A staining process can measure the percentage of tumor cells that are positive for Ki-67. More positive cells hasten in dividing and forming new cells. Proliferation index was measured by the percentage of cells staining for Ki-67.
