The monoclonal antibody Ki-67 detects a nuclear antigen that is present only in proliferating cells. The aim of the present investigation was to clarify whether the Ki-67 nuclear antigen is restricted in its expression to certain phases of the cell cycle. All experiments consistently showed that the Ki-67 nuclear antigen is present in S, G2, and M phase,(More)
The production of a mouse monoclonal antibody, Ki-67, is described. The Ki-67 antibody recognized a nuclear antigen present in proliferating cells, but absent in resting cells. Immunostainings with Ki-67 revealed nuclear reactivity in cells of germinal centres of cortical follicles, cortical thymocytes, neck cells of gastrointestinal mucosa,(More)
In this study the antigenic profile of Hodgkin (H) and Sternberg-Reed (SR) cells from cases of Hodgkin's disease was analysed using a large panel of monoclonal and polyclonal antibodies reactive with cells of lymphoid and haemotopoietic origin. The aim of this investigation was, firstly, to throw light on the origin of H and SR cells and, secondly, to(More)
We have generated a mouse line in which the cystic fibrosis transmembrane conductance regulator (CFTR) gene has been mutated by gene targeting. Like human cystic fibrosis (CF) patients, mice lacking a functional CFTR gene, referred to as CFTR(-/-) mice, show increased numbers of goblet cells and obstruction of glands with inspissated eosinophilic(More)
Staphylococcus aureus is one of the most common pathogens of bacterial corneal ulcers. It is generally believed that the first step necessary in the development of an infection involves adherence of bacteria to host tissue. The mechanisms by which staphylococci adhere to ocular epithelium have not yet been defined. An in vitro assay was used to measure(More)
To clarify the origin of Hodgkin (H) and Sternberg-Reed (SR) cells, frozen sections of lymph nodes from 30 patients with Hodgkin's disease were immunostained with a large panel of monoclonal antibodies reactive with cells of lymphoid tissue and granulopoiesis. The results showed that: (a) H and SR cells are devoid of markers specific to, or characteristic(More)
