In this study, a three-dimensional chitosan-gelatin/nanohydroxyapatite (ChG/nHaP) scaffold was successfully fabricated and characterized in terms of swelling, degradation, cell proliferation, cell attachment, and mineralization characterizations. The ChG/nHaP scaffold was fabricated with a mean pore size of 100-180 μm. Our results showed that the physicochemical and biological properties of the...
introduction: the native inability of nervous system to regenerate, encourage researchers to consider neural tissue engineering as a potential treatment for spinal cord injuries. considering the suitable characteristics of induced pluripotent stem cells (ipscs) for tissue regeneration applications, in this study we investigated the adhesion, viability and proliferation of neural progenitors (de...
collagen is the major protein component of cartilage, bone, skin and connective tissue and constitutes the major part of the extracellular matrix. collagen type i has complex structural hierarchy, which consists of treepolypeptide α-chains wound together in a rod-like helical structure. collagen is an important biomaterial, finding many applications in the field of tissue engineering. it has be...
objective: this study examined the in vivo differentiation of mesenchymal stem cells (mscs) into insulin producing cells (ipcs) on electrospun poly-l-lactide acid (plla) scaffolds coated with matricaria chammomila l. (chamomile) oil. materials and methods: in this interventional, experimental study adipose mscs (amscs) were isolated from 12 adult male new zealand white rabbits and characterized...
Biodegradable and biocompatible macromolecule chitosan has been favored for a variety of clinical applications. We reported herein the fabrication of a novel chitosan scaffold with high elasticity. This scaffold can be easily compressed and thus enable the insertion of such scaffold into surgical lesions during minimal invasive surgeries. In addition, this novel scaffold can restore its shape w...
In bone tissue engineering, the organo-ceramic composite, electrospun polycaprolactone/hydroxyapatite (PCL/HA) scaffold has the potential to support cell proliferation, migration, differentiation, and homeostasis. Here, we report the effect of PCL/HA scaffold in tissue regeneration using human mesenchymal stem cells (hMSCs). We characterized the scaffold by fourier transform infrared spectrosco...
The synthesis of a new triazacyclophane scaffold (TACO scaffold) containing three selectively deprotectable amines is described. The TACO scaffold is conformationally more constrained than our frequently used TAC scaffold, due to introduction of a substituent on the para position of the benzoic acid hinge, which prevents ring flipping and makes it more attractive than the TAC scaffold for prepa...
introduction perforation of maxillary sinus mucous membrane is of the most prevalent complication during open sinus lift surgery. moreover, such complication can usually be managed by an absorbable membrane. as far as absorbable membranes are concerned, decellularized maxillary sinus mucous membranes, which is an extracellular matrix, can be used as a biologic scaffold and insulating membrane i...
