The delivery of chemotherapeutics into tumor cells is a fundamental knot for tumor-target therapy to improve the curative effect and avoid side effects. Here, A54 peptide-functionalized poly(lactic-co-glycolic acid)-grafted dextran (A54-Dex-PLGA) was synthesized. The synthesized A54-Dex-PLGA self-assembled to form micelles with a low critical micelle concentration of 16.79 μg·mL(-1) and diamete...
Background and Aims: Tissue engineering is a relatively novel field that has been intensely developing during recent years and has shown to be excessively promising when used for cartilage regeneration. Scaffolds represent important components for tissue engineering. Materials and Methods: The Poly Lactic-Co-Glycolic Acid (PLGA) impregnated with fibrin and hyaluronic acid (HA) produce hybrid s...
چکیده زمینه و هدف: پلی لاکتید کو پلی گلیکولید (poly d,l-lactic-co-glycolic acid=plga) به عنوان پلیمری زیست سازگار و زیست تخریب پذیر شناخته شده است. این پلیمر اخیرا در مهندسی بافت بسیار مورد توجه قرار گرفته است. هدف از مطالعه ی حاضر بررسی رفتار بیولوژیک سلول های استرومایی مغز استخوان (=bmscs bone marrow stromal cells) در کشت با نانوالیاف plga پوشش داده شده با ژلاتین و یا پلی ال لایزین می باشد. ر...
Biodistribution of nanoparticles is dependent on their physicochemical properties (such as size, surface charge, and surface hydrophilicity). Clear and systematic understanding of nanoparticle properties' effects on their in vivo performance is of fundamental significance in nanoparticle design, development and optimization for medical applications, and toxicity evaluation. In the present study...
BACKGROUND 5-Aminolevulinic acid (ALA) is a prodrug for topical photodynamic therapy. The effectiveness of topical ALA can be limited by its bioavailability. The aim of this study was to develop a novel ALA delivery approach using poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs). METHODS A modified double emulsion solvent evaporation method was used to prepare ALA loaded PLGA NPs (ALA...
BACKGROUND To mimic the muscle inspired cells adhesion through proteins secretion, the lamination of collagen-hydroxyapatite nanorod (nHA) composite nanofibers has been carried out successfully on polydopamine (PDA)-coated microfibrous polylactide-co-glycolide (PLGA) fabrics. The lamination of collagen-hydroxyapatite composite nanofibers on polydopamine-coated microfibrous PLGA fabrics was carr...
A mesoporous bioactive glass (MBG) surface modified with poly(lactic-co-glycolic acid) (PLGA) electrospun fibrous scaffold for bone regeneration was prepared by dip-coating a PLGA electrospun fibrous scaffold into MBG precursor solution. Different surface structures and properties were acquired by different coating times. Surface morphology, chemical composition, microstructure, pore size distr...
In the preliminary study, we have found an excellent osteogenic property of nanohydroxyapatite/chitosan/poly(lactide-co-glycolide) (nHA/CS/PLGA) scaffolds seeded with human umbilical cord mesenchymal stem cells (hUCMSCs) in vitro and subcutaneously in the nude mice. The aim of this study was to further evaluate the osteogenic capacity of nHA/CS/PLGA scaffolds seeded with hUCMSCs in the calvaria...
