background: surface properties of a biomaterial could be critical in determining biomaterial’s biocompatibility due to the fact that the first interactions between the biological environment and artificial materials are most likely occurred at material’s surface. in this study, the surface properties of a new nanocomposite (nc) polymeric material were modified by combining plasma treatment and ...

Background: Extensive full-thickness burns require replacement of both epidermis and dermis. In designing skin replacements, the goal has been to re-create this model and make a product which has both essential components. Methods: In the present study, we developed procedures for establishing confluent, stratified layers of cultured human keratinocytes on the surface of modified collagen-chito...

Acid-soluble collagen could be isolated from fish skin using acetic acid. In recent years, much attention has been paid to collagen from marine sources, mainly arising from the fact that there is no risk of contagious diseases. Moreover, by processing the fish, significant amounts of waste materials are produced which can be considered as a substitute for these collagen sources. Thunnus tonggol...

Background  Recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (LLLT). The aim of this study was to determine whether LLLT could induce a bio-stimulatory effects on human gingival fibroblasts (HGF3-PI 53). Therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type I gene ...

Collagen meshes with large or small openings were prepared after selective removal of PLGA mesh from PLGA–collagen composite collagen-coated mesh. The collagen support human skin fibroblast adhesion and promote cell proliferation.

  Objective(s): Osteoarthritis is one of the most common diseases in middle-aged population in the world. Cartilage tissue engineering (TE) has been presented as an effort to introduce the best combination of cells, biomaterial scaffolds and stimulating growth factors to produce a cartilage tissue similar to the natural articular cartilage. In this study, the chondrogenic potential of adipose d...
