Ki-67 Information for Pathologists


Marker of cell proliferation first described in 1983 (Int J Cancer 1983;31:13). Name derived from Kiel, Germany (city of origin) and the clone number in the 96 well plate (Wikipedia). Labile, nonhistone nuclear protein expressed in G1, S, G2 and M phases of cell cycle, then rapidly catabolized at end of M phase and not detectable in G0 and early G1 cells (J Cell Physiol 2000;182:311). MIB1 is the IgG1 antibody against Ki67 for formalin fixed, paraffin embedded tissue. Essential features

Common Uses By Pathologists:

Nuclear stain; cytoplasmic staining is disregarded. Distinguish benign / nonneoplastic and malignant / neoplastic lesions:. Anus / cervix: HSIL (Ki67+) versus atrophy or normal (Ki67-, Am J Surg Pathol 2010;34:1449). Colonic polyp with cautery artifact: distinguish adenoma (Ki67+) from nonadenomatous polyp (Ki67-, Arch Pathol Lab Med 2007;131:1089). Lymph node, sentinel node biopsy: distinguish melanoma (Ki67+) from nevus cells (Ki67-, Am J Surg Pathol 2002;26:1351).
