Poly(Lactic-co-Glycolic Acid): Applications and Future Prospects for Periodontal Tissue Regeneration
Periodontal tissue regeneration is the ultimate goal of the treatment for periodontitis-affected teeth. The success of regenerative modalities relies heavily on the utilization of appropriate biomaterials with specific properties. Poly (lactic-co-glycolic acid) (PLGA), a synthetic aliphatic polyester, has been actively investigated for periodontal therapy due to its favorable mechanical propert...
Poly(lactic-co-glycolic acid) (PLGA) nanoparticles were studied as drug delivery vehicles for calcitriol, the active form of vitamin D3. In vitro effects of calcitriol encapsulated in PLGA nanoparticles were evaluated with respect to free calcitriol on human pancreatic cell lines, S2-013 and hTERT-HPNE, and the lung cancer cell line A549. Encapsulated calcitriol retained its biological activity...
Biodegradable porous biomaterial scaffolds play a critical role in bone regeneration. In this study, the porous nano-hydroxyapatite/collagen/poly(lactic-co-glycolic acid)/graphene oxide (nHAC/PLGA/GO) composite scaffolds containing different amount of GO were fabricated by freeze-drying method. The results show that the synthesized scaffolds possess a three-dimensional porous structure. GO slig...
The aim of this study is to investigate the applicability of poly(lactic-co-glycolic acid) (PLGA)/collagen composite scaffold for skin tissue engineering. PLGA and collagen were dissolved in HFIP as a common solvent and fibrous scaffolds were prepared by electrospinning method. The scaffolds were characterized by scanning electron microscopy (SEM), FTIR spectroscopy, mercury porosimetry, tensil...
Biodegradable poly (lactic-co-glycolic acid) (PLGA) microparticles are an effective way to achieve sustained drug release. In this study, we investigated a sustained release model of PLGA microparticles with incorporated protein via either emulsion or coaxial electrospray techniques. PLGA (75:25) was used as the carrier, and bovine serum albumin as a model protein. Coaxial electrospray resulted...
Core-shell alginate-poly (lactic-co-glycolic) acid (PLGA) microparticles are potential candidates to improve hydrophilic drug loading while facilitating controlled release. This report studies the influence of the alginate core size on the drug release profile of alginate-PLGA microparticles and its size. Microparticles are synthesized through double-emulsion fabrication via a concurrent ionotr...
Drug-eluting stents (DES) are commonly used in coronary angioplasty procedures. A DES elutes drug compounds from a thin polymeric coating into the surrounding coronary artery tissue to reduce in-stent restenosis (a significant lumen loss due to growth of vascular tissue). Biodurable (non-erodible) polymers are often used in the current DES coatings, which stay permanently in the patients. While...
Introduction: Poly lactic co- glycolic acid (PLGA) and poly caprolacton (PCL) are highly applicable polymers in the field of drug delivery and tissue engineering scaffolds. Therefore, this study aimed to design an insulin-loaded PCL/PLGA hybrid nanofiber scaffold in order to be applied in attachment and growth of chondrocytes. Moreover, it can provide a vehicle for the controlled release of a...
There has been a growing interest in the design and development of polymeric microspheres as controlled release systems for drugs and antigens. Different types of polymers have been used to design biodegradable polymeric microparticles. Poly(lactic-co-glycolic) acid (PLGA) microspheres have been extensively investigated because of their biocompatibility and biodegradability. PLGA has been appro...
