The interaction of fibronectin fragments with fibroblastic cells.

Fibronectin mediates adherence of rat alveolar type II epithelial cells via the fibroblastic cell-attachment domain.

The lung alveolar surface is composed of types I and II epithelial cells. Extremely attenuated type I cells cover 90% of the surface and are prone to necrosis during acute lung injury. After denudation of type I cells, the alveolar epithelium is restored by proliferation of type II cells. During reepithelialization in vivo the type II cells have been observed to reorganize on an extracellular m...

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...

Fibronectin-plasma membrane interaction in the adhesion of hemopoietic cells

Many hemopoietic cell lines were examined for their ability to adhere to culture dishes coated with extracellular matrix proteins. Adhesion assay was performed with murine and human leukemic cell lines representative of different stages of differentiation along both erythroid and myeloid lineages. All the hemopoietic cell lines tested adhered to fibronectin but not to laminin, types I, III, and...

Fibroblastic Reticular Cells: Organization

Neuron-specific interactions with two neurite-promoting fragments of fibronectin.

Proteolytic fragments of fibronectin were used to identify regions of the molecule that support neurite extension and to investigate further the differential behavior of central and peripheral nervous system neurons in response to fibronectin (Rogers, S. L., P. C. Letourneau, S. L. Palm, J. B. McCarthy, and L. T. Furcht (1983) Dev. Biol. 98: 212-220). Fibronectin fragments with differing biolog...
