| cellular biology | <study> The study of cells. Implies the use of light or electron microscopic methods for the study of morphology. (18 Nov 1997) |
|---|---|
| cellular biophysics | Biophysics concerned with cellular processes. (05 Mar 2000) |
| cellular blue nevus | A large, acquired blue nevus in which melanocytes are often clear and large, alternating with pigmented spindle cells and which may expand deeply into the subcutis; malignant change is very rare. (05 Mar 2000) |
| cellular cartilage | An embryonic or immature stage of cartilage in which it consists chiefly of cells with very little matrix. Synonym: parenchymatous cartilage. (05 Mar 2000) |
| cellular embolism | Embolism due to a mass of cells transported from disintegrating tissue. (05 Mar 2000) |
| cellular engineering | <technique> The use of techniques for constructing replacement or additional or experimental parts of cells and tissues for both fundamental investigation and as prosthetic devices. Often involves the interfacing of cells and nonliving structures. (26 Mar 1998) |
| cellular immune theory | A concept, put forth by Elie Metchnikoff, that cells, not antibodies, were responsible for the immune response of an organism. (05 Mar 2000) |
| cellular immunity | <cell biology, immunology> Immune response that involves enhanced activity by phagocytic cells and does not imply lymphocyte involvement. Since the term is easily confused with cell-mediated immunity its use in this sense should be avoided. (26 Mar 1998) |
| cellular immunity deficiency syndrome | <syndrome> A syndrome marked by increased susceptibility to infection, especially to viral infection, associated with defective functioning of the mechanism responsible for acquired immunity of the cell-mediated kind. See: immunodeficiency. (05 Mar 2000) |
| cellular immunodeficiency with abnormal immunoglobulin synthesis | An ill-defined group of sporadic disorders of unknown cause, occurring in both males and females and associated with recurrent bacterial, fungal, protozoal, and viral infections; there is thymic hypoplasia with depressed cellular (T-lymphocyte) immunity combined with defective humoral (B-lymphocyte) immunity, although immunoglobulin levels may be normal. Synonym: Nezelof syndrome, Nezelof type of thymic alymphoplasia. (05 Mar 2000) |
| cellular microbiology | <study> A new discipline emerging at the interface between cell biology and microbiology. One major focus of this new field is on the interference of pathogenic bacteria with many eukaryotic cell functions, such as maturation of intracellular compartments, internal cellular communication, or even cell division and differentiation. The study of cellular mcirobiology in this respect, is providing a sophisticaled tool kit for mammalian cell biologists. (26 Mar 1998) |
| cellular mosaicism | A chimerism in which a tissue contains cells from different zygotes; e.g., in humans, involving erythrocytes. (05 Mar 2000) |
| cellular oncogene | <molecular biology> A normal gene that, when mutated or improperly expressed, can cause cancer to develop. (09 Oct 1997) |
| cellular pathology | The interpretation of diseases in terms of cellular alterations, i.e., the ways in which cells fail to maintain homeostasis, sometimes used as a synonym for cytopathology. (05 Mar 2000) |
| cellular polyp | A polyp that consists of benign neoplastic tissue derived from glandular epithelium. Synonym: cellular polyp, polypoid adenoma. (05 Mar 2000) |
