Disease relevance of FN1

 

High impact information on FN1

  • Recent studies have reported improved efficiency by including stromal cells (STR), or the fibronectin fragment CH-296 (FN), and various cytokines such as flt3 ligand (FLT) during ex vivo culture and transduction in nonhuman primates [5].
  • Antibodies to vascular basement membrane and matrix markers laminin, fibronectin, and collagen types I and VIII, and antisera recognizing cell cycle-specific nuclear proteins (cyclin, Ki-67, Mib-1) also were used [6].
  • METHODS: The impact of culture and transduction on rhesus macaque CD34+ peripheral blood stem cells (PBSCs) was assessed in the presence of FN and stimulatory cytokines [7].
  • In the current study, we investigated whether prolonged culture and transduction in the presence of the carboxy-terminal portion of fibronectin (FN) could maintain or expand retrovirally transduced repopulating hematopoietic stem cells (HSCs) [7].
  • Levels of FFN in amnion increase with the onset of labor in rhesus monkeys [8].
 

Biological context of FN1

 

Anatomical context of FN1

  • We conclude that GC differentially regulates FFN expression in epithelial and mesenchymal cells from amnion and placenta [8].
  • CONCLUSIONS: These results suggest that culture on FN support allows prolonged ex vivo maintenance and even expansion of transduced repopulating stem cells [7].
  • Cultured simian astrocytes expressed vimentin, laminin, and fibronectin [13].
  • As macrophages, they expressed in vitro CD68, CD64, CD14, CD11b, MHC class II, and fibronectin [13].
  • During this period the trophoblast cells in the proximal shell reorganized, forming strands of cells that were separated by bands of matrix immunoreactive for type IV collagen, laminin, and fibronectin [14].
 

Associations of FN1 with chemical compounds

  • Cells were maintained with and without dexamethasone (DEX), and levels of FFN in the conditioned media were determined by ELISA [8].
  • Aqueous humor fibronectin levels were determined in four monkeys after approximately 9.5 weeks of timolol + dorzolamide treatment [15].
  • Our findings indicate that timolol affects neither ciliary epithelial transport of ascorbate nor aqueous fibronectin levels [15].
  • Surfaces on the experimental sides were decalcified with citric acid, and after thorough rinsing, the inner aspect of the flaps and the roots were bathed with 1 ml of autologous plasma fibronectin in normal saline (400 micrograms m/ml) and the flaps sutured [10].
  • Immunoperoxidase staining showed that these structures contained major basement membrane components including laminin, heparan sulfate proteoglycan, type IV collagen, as well as fibronectin [16].
 

Regulatory relationships of FN1

  • In the absence of serum, VEGF stimulated proliferation of UEA-1 (+) cells plated on fibronectin but not collagen I, whereas in the presence of 10% fetal calf serum, both matrices supported VEGF-induced mitogenesis [17].
