Ki-67 antigen is a nuclear antigen specifically associated with cell proliferation. Ki-67 is expressed in all proliferating cells that are in the active phases of the cell cycle (late G1, S, G2, and mitosis), but absent in resting cells. In G1, it is predominately localized in the perinucleolar region and also found in nuclear matrix in the later phases (1). Ki-67 is thought to be involved in the maintaining of cell proliferation, however, its exact mechanism for function is unknown. Due to the fact that Ki-67 can be used to determine the growth fraction (the proportion of the cells committed to the cell cycle), it is considered to be an important marker in human tumor diagnostics and prognostics (2).
