TL;DR: The data suggest that the early stages of mitogen stimulation represent initial sequences of proliferation and not parts of the cell cycle, and immunostaining with monoclonal antibody Ki-67 provides a reliable means of rapidly evaluating the growth fraction of normal and neoplastic human cell populations.

TL;DR: A first series of immunostainings of tumour biopsies indicated that Ki‐67 may be a potent tool for easy and quick evaluation of the proportion of proliferating cells in a tumour.

TL;DR: Results obtained indicate that Ki-1 antigen is an inducible lymphoid-associated molecule that identifies a group of hitherto poorly characterized normal and neoplastic large lymphoid cells in Hodgkin's disease and Disorders in which only a minority of cells express Ki- 1 antigen probably represent lesions in whichonly some of the abnormal cells have transformed into an "activation state.

TL;DR: Production of mouse monoclonal antibodies against the Hodgkin cell line L428 was described and one hybridoma antibody was found to be specific for H and SR cells of all Hodgkin's lymphomas tested and a minute, but distinct new cell population in normal tonsils and lymph nodes.

TL;DR: It is suggested that the hitherto unknown cell population detected with the monoclonal antibody Ki‐I in normal lymphoid tissue is the normal equivalent of H and SR cells.
