The function of scaffolding proteins is to bring together two or more proteins in a relatively stable configuration, hence their name. Numerous scaffolding proteins are found in nature, many having multiple protein-protein interaction modules. Over the past decade, examples of scaffolding complexes long thought to be stable have instead been found to be surprisingly dynamic. These studies are s...

InaD, a Drosophila photoreceptor scaffolding protein, assembles multiple signal-transducing proteins at the membrane via its five PDZ domains, enhancing speed and efficiency of vision. Extensive conservation of PDZ domains suggests that these motifs have a general role in organizing diverse signaling complexes.

Avulsed teeth that are replanted dried are more prone to loss. Recent tissue engineering studies focus onfabrication of various cell delivery systems to improve the overall prognosis of such teeth. To evaluate this newcell transplant method, we initially aimed at designing of PRF scaffold and determining BMMSCs viabilityand function on the fabricated scaffold. To test this concept in-vitro, hum...

The aim of this study was to find a proper method for improvement of ischemic condition in the rat hind limb and also to observe the efficacy of cell engraftment with alginate/gelatin three-dimensional scaffolds. Eighteen male Wistar rats weighing 200 to 250 g were randomly divided into three groups (n = 6) including a) ischemia group; in which femoral artery was removed after ligation at the d...

Background: Tissue engineering using Stem cell from Human Exfoliated Deciduous Teeth (SHED) and a natural biomaterials biomaterial scaffold has become a promising therapy for the alveolar bone defect. The aim of this study was to analyze the Osteoprotegerin (OPG) and Receptor Activator of NF-Κb ligand (RANKL) expression after the application of Hydroxyapatite scaffold and SHED.Methods: A labora...

The prototyping of tissue-engineered bone scaffold (calcined goat spongy bone-biphasic ceramic composite/PVA gel) by 3D printing was performed, and the biocompatibility of the fabricated bone scaffold was studied. Pre-designed STL file was imported into the GXYZ303010-XYLE 3D printing system, and the tissue-engineered bone scaffold was fabricated by 3D printing using gel extrusion. Rabbit bone ...

Graphene oxide (GO) consisting of a carbon monolayer has been widely investigated for tissue engineering platforms because of its unique properties. For this study, we fabricated a GO-applied scaffold and assessed the cellular and tissue behaviors in the scaffold. A preclinical test was conducted to ascertain whether the GO scaffold promoted bone induction in dog tooth extraction sockets. For t...
