Term:abnormal basement membrane morphology
go back to main search page
Accession:MP:0004272 term browser browse the term
Definition:anomaly in the structure, organization and/or placement of the extracellular supportive tissue adjacent to the basal surface of the epithelia, including the epithelium of muscle cells, fat cells and Schwann cells; it is comprised of type IV collagen, laminin, and sulfated proteoglycans and other components and consists of two layers, the basal lamina and the lamina reticularis
Comment:Note: Basal lamina and lamina reticularis (or of two basal laminae) compose the basement membrane. Thus, in strict sense, the term basement membrane is different from and should not be confused with basal lamina.
Synonyms:exact_synonym: abnormal basement lamina morphology;   basement membrane dysplasia
