We evaluated the healing potential of human fetal aorta-derived CD133(+) progenitor cells and their conditioned medium (CD133(+) CCM) in a new model of ischemic diabetic ulcer. Streptozotocin-induced diabetic mice underwent bilateral limb ischemia and wounding. One wound was covered with collagen containing 2x10(4) CD133(+) or CD133(-) cells or vehicle. The contralateral wound, covered with onl...
Secreted Frizzled Related Proteins (Sfrps) are a family of secreted proteins that can bind both to Wnt ligands and Frizzled receptors, thereby modulating the Wnt signalling cascades. Recent studies have shown that Sfrps can also interact with Wnt unrelated molecules such as RANKL, a member of the tumor necrosis factor family, Tolloid metalloproteinases or integrin-fibronectin complexes. Alterat...
The use of short fiber reinforced polymers (SFRP) is increasing steadily in automotive and aerospace industry due to its mechanical properties and light weight. The mechanical and physical properties of SFRP depend on the geometrical characteristics of the reinforcing material. Under tensile stress various defects are induced in SFRP composites. X-ray computed tomography (XCT) is a non-destruct...
BACKGROUND Wnt signaling plays an important role in development and maintenance of many organs and tissues. The most-studied secreted Wnt inhibitors are sclerostin (SOST), Dickkopf-related protein 1 (DKK-1), and secreted frizzled related protein 1 (SFRP-1) which play important roles in bone turnover. The present study investigated the relationship between serum Wnt inhibitors and diseases with ...
Introduction: Astrocytes, the most abundant glia in the central nervous system, modulate neuronal survival and function. Astrocytic functions are mediated by synthesis and secretion of wide ranges of polypeptides through mechanism (s) poorly understood. Among these, TGFβs are synthesized and released by the astrocytes. In this study, the involvement of Wnt signaling pathway on the synthesi...
We investigated the expression of the secreted frizzled-related proteins (SFRPs) in keratoconus (KC) and control corneas. KC buttons (∼8 mm diameter) (n = 15) and whole control corneas (n = 7) were fixed in 10% formalin or 2% paraformaldehyde and subsequently paraffin embedded and sectioned. Sections for histopathology were stained with hematoxylin and eosin, or Periodic Acid Schiff's reagent. ...
Development of the metanephric kidney is an experimental model system to analyze interactions between mesenchymal and epithelial cells and mesenchymal-epithelial transition. To study the underlying genetic mechanisms we employed organ culture and differential display PCR to identify genes regulated upon induction of mesenchymal cells. One of the genes found encodes the secreted frizzled related...
This paper presents an analytical method considering the effects of fiber length and fiber orientation distributions for predicting the tensile strength (TS) of short-fiber-reinforced polymers (SFRP). Two probability density functions are used for modelling the distributions of fiber length and fiber orientation. The strength of SFRP is derived as a functiolz of fiber length and fiber orientati...
We present a Bayesian methodology to infer the elastic modulus of constituent polymer and fiber orientation state in short-fiber reinforced composite (SFRP). The properties are inversely determined using only few experimental tests. Developing manufacturing digital twins for SFRP processes, including injection molding extrusion deposition additive (EDAM) requires extensive material characteriza...
