One of the fundamental principles underlying tissue engineering approaches is that newly formed must maintain sufficient vascularization to support its growth. Efforts induce vascular growth into tissue-engineered scaffolds have recently been dedicated developing novel strategies deliver specific biological factors direct recruitment endothelial cell (EC) progenitors and their differentiation. The challenge, however, lies in orchestration cells, appropriate factors, optimal factor doses....

Wound healing is a complex physiological process that controlled by well-orchestrated cascade of interdependent biochemical and cellular events, which has spurred the development therapeutics simultaneously target these active constituents. We assessed potential Parrotia persica (Hamamelidaceae) in wound repair analyzing regenerative effects its two main phenolic compounds, myricetin-3-O-β-rhamnoside chlorogenic acid. To accomplish this, we performed phytochemical profiling characterized...

Resveratrol (RSV) and nicotinamide (NAM) have garnered considerable attention due to their anti-inflammatory anti-aging properties. NAM is a transient inhibitor of class III histone deacetylase SIRTs (silent mating type information regulation 2 homologs) SIRT1 an poly-ADP-ribose polymerase-1 (PARP1). The debate on the relationship between RSV has precluded use as therapeutic drug. Recent work demonstrated that facilitates tyrosyl-tRNA synthetase (TyrRS)-dependent activation PARP1. Moreover,...

Cancer has arisen to be of the most prominent health care issues across world in recent years. Doctors have used physiological intervention as well chemical and radioactive therapeutics treat cancer thus far. As an alternative current methods, gene delivery systems with high efficiency, specificity, safety that can reduce side effects such necrosis tissue are under development. Although viral vectors highly efficient, concerns from fact sourced lethal diseases. With this mind, rod shaped...

A wide variety of environmental factors including physical and biochemical signals are responsible for stem cell behavior function. In particular, matrix elasticity shape have been shown to determine function, yet little is known about the interplay between how these cues control differentiation. For first time, by using ultraviolet (UV) lithography pattern poly(ethylene) glycol (PEG) hydrogels, it possible manufacture microenvironments capable parsing effects elasticity, shape, size in...

Abstract Regenerative engineering approaches utilizing biomimetic synthetic scaffolds provide alternative strategies to repair and restore damaged bone. The efficacy of the for functional bone regeneration critically depends on their ability induce support vascular infiltration. In present study, three‐dimensional (3D) poly(lactide‐ co ‐glycolide) (PLAGA) sintered microsphere were developed by sintering together PLAGA microspheres followed nucleation minerals in a simulated body fluid....

Current methods of treating critical size bone defects include autografts and allografts, however, both present major limitations including donor-site morbidity, risk disease transmission, immune rejection. Tissue engineering provides a promising alternative to circumvent these shortcomings through the use autologous cells, three-dimensional scaffolds, growth factors. We investigated development scaffold with native extracellular matrix (ECM) components for directing osteogenic...

Targeted therapies have changed the treatment of cancer, giving new hope to many patients in recent years. The shortcomings targeted including acquired resistance, limited susceptible patients, high cost, and toxicities, led necessity combining these with other or chemotherapeutic treatments. Natural products are uniquely capable synergizing non-targeted anticancer regimens due their ability affect multiple cellular pathways simultaneously. Compounds which provide an additive effect often...

Abstract Bone tissue engineering offers promising alternatives to repair and restore tissues. Our laboratory has employed poly(lactid‐co‐glycolide) PLAGA microspheres develop a three dimensional (3‐D) porous bioresorbable scaffold with biomimetic pore structure. Osseous healing integration the surrounding depends in part on new blood vessel formation within Since endothelial cells play key role angiogenesis (formation of vessels from pre‐existing vasculature), purpose this study was better...

Targeted therapies have become the focus of much cancer therapy research conducted in United States. While these made vast improvements treatment cancer, their results been somewhat disappointing due to acquired resistances, high cost, and limited populations susceptible patients. As a result, targeted therapeutics are often combined with other or chemotherapies. Compounds which target more than one related pathway rare, but potential synergize multiple components therapeutic cocktails....

Tissue engineering uses various approaches to restore bone loss and heal critical-size defects resulting from trauma, infection, tumor resection or other musculoskeletal diseases. The success of tissue strategies critically depends on the extent blood vessel infiltration into scaffolds. It has been demonstrated that invasion host scaffolds is limited a depth several hundred micrometers. Limited perfusion restricts formation in central regions scaffold, leads cell viability this region...

Cell-based angiogenic therapies offer potential for the repair of ischemic injuries, while avoiding several limitations associated with material-based growth factor delivery strategies. Evidence supports that applying MSCs as spheroids rather than dispersed cells can improve retention and enhance therapeutic effect through increased secretion factors due to hypoxia. However, spheroid culture appears modulate MSC behavior, there has been little investigation how major parameters affect...

Control over angiogenesis (formation of new capillaries from preexisting vessels) is often a crucial requirement for implantable porous biomaterials serving as scaffolds tissue regeneration. Angiogenesis influenced by the transport chemoattractants such vascular endothelial growth factor (VEGF) through implant. To investigate this influence, we developed computational model capillary formation based on cell migration modeling random motion sprout tips biased along spatially and temporally...

The physiology of wound healing is dependent on the crosstalk between inflammatory mediators and cellular components skin regeneration including fibroblasts endothelial cells. Therefore, strategies to promote must regulate this achieve maximum efficacy. In light remarkable potential natural compounds target multiple signaling mechanisms, study aims demonstrate hypermongone C, a polycyclic polyprenylated acylphloroglucinol (PPAP), accelerate closure by concurrently enhancing fibroblast...

A number of bone tissue engineering approaches are aimed at (i) increasing the osteconductivity and osteoinductivity matrices, (ii) incorporating bioactive molecules within scaffolds. In this study we examined growth a nano-crystalline mineral layer on poly(lactide-co-glycolide) (PLAGA) sintered microsphere scaffolds for engineering. addition, influence precipitate protein adsorption was studied. Scaffolds were mineralized by incubation in simulated body fluid (SBF). Scanning electron...
