The cell membrane is not only a physical barrier, but also functional organelle that regulates the communication between and its environment. ability to functionalize with synthetic molecules or nanostructures would advance cellular functions beyond what evolution has provided. aim of this Minireview introduce recent progress in using DNA DNA-based for cell-surface engineering. We first chemica...

Branching morphogenesis, a specialized part of leads to the formation microstructures (tubes, canals, and glands), source active organ functions. The dynamic mechanisms involved are appearance/disappearance biomolecules morphogens gradients. In context angiogenesis, growth factors allow initiation, regulation, remodeling blood vessels. particular case micro-vascularization, it seems essential r...

The future development of medicine will greatly depend on research, knowledge and clinical application of stem cells. In recent years, stem cells especially; skin stem cells have been very interesting and amazing targets for study and scientific application in the following fields : 1- Cell-based therapy; 2- Regenerative medicine and tissue engineering; 3- Gene therapy; 4- Therapeutic cloning; ...

background: recently, tissue engineering has developed approaches for repair and restoration of damaged skeletal system based on different scaffolds and cells. this study evaluated the ability of differentiated osteoblasts from adipose‑derived stem cells (adscs) seeded into hydroxyapatite/ tricalcium phosphate (ha‑tcp) to repair bone. methods: in this study, adscs of 6 canines were seeded in ha...

In biotechnology has been concentrated to review alternative routes for the production of natural compounds. Plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. However, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...

Electrospinning has been recognized as an efficient technique for the fabrication of polymernanofibers. Recently, various polymers have successfully been electrospun into ultrafine fibers.Electrospinning is an extremely promising method for the preparation of tissue engineering scaffolds.In this study, nanofibers gelatin was electrospun at 20% v/v optimized content. To produce...
