The role of matricellular proteins in bacterial containment and in the induction of pathogen-specific adaptive immune responses is unknown. We studied the function of the matricellular protein secreted protein, acidic and rich in cysteine (SPARC/osteonectin) in the dissemination of locally injected Salmonella typhimurium and in the subsequent immune response. We show that SPARC was required for...

AIM To investigate the role of Wnt5a in the process of differentiation of human dental papilla cells (HDPCs). METHODOLOGY Recombinant adenovirus encoding full-length Wnt5a cDNA was constructed to investigate the biological role of Wnt5a on the differentiation of HDPCs. The effect of Wnt5a on HDPCs differentiation was determined by ALP activity assay, ALP staining and mineral induction assay. ...

Vascular calcification is a prominent feature of atherosclerosis but the mechanisms underlying vascular calcification are still obscure. Since bone-associated proteins such as osteonectin, osteocalcin, and matrix Gla protein have been detected in calcified vascular tissues, calcification has been considered to be an organized, regulated process similar to mineralization in bone tissue. Vascular...

Osteosarcomas are the most abundant form of bone malignancies in multiple species. Canine osteosarcomas are considered a valuable model for human osteosarcomas because of their similar features. Feline osteosarcomas, on the other hand, are rarely studied but have interesting characteristics, such as a better survival prognosis than dogs or humans, and less likelihood of metastasis. To enable ex...
