INTRODUCTION: Restoration of acquired, congenital, or age-related soft tissue defects using autologous or implantable materials can cause donor site morbidity, infection, device failure, and fibrosis. Injectable fillers are limited by variable resorption and fat grafting causes necrosis in large volumes. An alternative approach using the body’s regenerative capacity and an injectable synthetic ...

A modified degumming technique, involving boiling in 0.25% Na2CO3 with addition of 1% sodium dodecyl sulphate and intermittent ultrasonic agitation, was developed for knitted silk scaffolds. Sericin was efficiently removed, while mechanical and structural properties of native silk fibroin were preserved. Biocompatible and mechanically robust hybrid nano-microscaffolds were fabricated by coating...

Biological hydrogels consisting of self-assembling peptide nanofibers are potentially excellent materials for various controlled molecular release applications. The individual nanofiber consists of ionic self-complementary peptides with 16 amino acids (RADA16, Ac-RADARADARADARADA-CONH(2)) that are characterized by a stable beta-sheet structure and undergo self-assembly into hydrogels containing...

INTRODUCTION Dilated cardiomyopathy is a major cause of progressive heart failure. Utilization of stem cell therapy offers a potential means of regenerating viable cardiac tissue. However, a major obstacle to stem cell therapy is the delivery and survival of implanted stem cells in the ischemic heart. To address this issue, we have developed a biomimetic aligned nanofibrous cardiac patch and ch...

Neural progenitor cells were encapsulated in vitro within a three-dimensional network of nanofibers formed by self-assembly of peptide amphiphile molecules. The self-assembly is triggered by mixing cell suspensions in media with dilute aqueous solutions of the molecules, and cells survive the growth of the nanofibers around them. These nanofibers were designed to present to cells the neurite-pr...

Background: Nano-scaffolds loaded with bioactive compounds such as ZnO nanoparticles (ZnO-NPs), tissue-engineered artificial skin grafts, can be a suitable substitute for extracellular matrix and greatly contribute to accelerating chronic wound treatment by decreasing the chance of bacterial infection. Methods: Silk fibroin nanofiber was fabricated using electrospinning three-dimensional porous...

spinal cord injury (sci) in humans remains a devastating and incurable disorder. a very important obstacle in axonal regeneration after spinal cord injury is astroglial scaring. the use of self-assembling peptide nanofiber, a hydrogel mimicking extracellular matrix, has been suggested as a scaffold for spinal cord regeneration and inhibition of astrogliosis. however, neurogenesis potential of l...
