objective: we studied both the presence of some carbohydrate compounds in a three-dimensional (3d) matrix harvested from human gingiva and the cell behavior in this matrix. materials and methods: in this experimental research, in order to prepare 3d scaffolds, human palatal gingival biopsies were harvested and physically decellularized by freeze-thawing and sodium dodecyl sulfate (sds). the sca...

objective(s)tissue engineering is an attractive science because it promises new therapeutic strategies for repairing organs that have lost functions due to damage. the purpose of this study was to evaluate induction effect of human gingival scaffold in tissue engineering for skin regeneration.materials and methodstissue samples were obtained from crown-lengthening procedures and wisdom teeth re...

background: development of tissue engineering and regenerative medicine has led to designing scaffolds and their modification to provide a better microenvironment which mimics the natural niche of the cells. gelatin surface modification was applied to improve scaffold flexibility and cytocompatibility. methods: plla/pcl aligned fibrous scaffold was fabricated using electrospinning method. adscs...

there are two main methods for preparing the puramatrix (pm) as a three-dimensional (3-d) scaffold for supporting the cells including surface plating and encapsulation. in the surface-plating procedure, the scaffold is created by adding an ionic agent such as medium to pm. after adjusting the ph by changing the medium, cells are seeded on top of the scaffold. in the encapsulation method, pm and...

to date, various approaches have been used in attempt to treat spinal cord injury (sci) but there is no definite treatment for repair of the damaged tissue. it is well known that sci results in a loss of neural tissues and formation of cystic cavities that inhibit regeneration of axons. tissue engineering, in which cells, signals and scaffolds are combined, is one of the most promising areas of...
