An immunomorphologic study was made of expression of intermediate filament proteins--keratin and vimentin--in the structures formed in branching tubulogenesis of Madin-Darby Canine Kidney epithelial cells (MDCK, clone 20), cultured in three-dimensional collagen gel in the presence of the "scatter factor" (HGF/SF). An improved method of parallel immunostaining of the whole branching structures and of their cryostat cross-sections was used. It was shown that both the discoid epithelial cells, forming walls of tubules with inner clear spaces, and the fibroblast-like cells invading the collagenic gel coexpressed keratin and vimentin. Thus, in the studied system of simplified morphogenesis in vitro, some conservatism of intermediate filament protein expression was revealed which does not respond to changes in cell shape or cell localization.

UI	MeSH Term	Description	Entries
D007633	Keratins	A class of fibrous proteins or scleroproteins that represents the principal constituent of EPIDERMIS; HAIR; NAILS; horny tissues, and the organic matrix of tooth ENAMEL. Two major conformational groups have been characterized, alpha-keratin, whose peptide backbone forms a coiled-coil alpha helical structure consisting of TYPE I KERATIN and a TYPE II KERATIN, and beta-keratin, whose backbone forms a zigzag or pleated sheet structure. alpha-Keratins have been classified into at least 20 subtypes. In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.

D002460	Cell Line	Established cell cultures that have the potential to propagate indefinitely.	Cell Lines,Line, Cell,Lines, Cell
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014746	Vimentin	An intermediate filament protein found in most differentiating cells, in cells grown in tissue culture, and in certain fully differentiated cells. Its insolubility suggests that it serves a structural function in the cytoplasm. MW 52,000.
D017228	Hepatocyte Growth Factor	Multifunctional growth factor which regulates both cell growth and cell motility. It exerts a strong mitogenic effect on hepatocytes and primary epithelial cells. Its receptor is PROTO-ONCOGENE PROTEINS C-MET.	Hepatopoietin,Hepatopoietin A,Scatter Factor,Factor, Hepatocyte Growth,Factor, Scatter,Growth Factor, Hepatocyte
D019084	Fluorescent Antibody Technique, Indirect	A form of fluorescent antibody technique commonly used to detect serum antibodies and immune complexes in tissues and microorganisms in specimens from patients with infectious diseases. The technique involves formation of an antigen-antibody complex which is labeled with fluorescein-conjugated anti-immunoglobulin antibody.
