To explore therapeutic potential of engineered neural tissue, we combined genetically modified neural stem cells (NSCs) and poly(lactic acid-co-glycolic acid) (PLGA) polymers to generate an artificial neural network in vitro. NSCs transfected with either NT-3 or its receptor TrkC gene were seeded into PLGA scaffold. The NSCs were widely distributed and viable in the scaffold after culturing for...

Targeting drugs to their sites of action is still a major challenge in pharmaceutical research. In this study, polylactic-co-glycolic acid (PLGA) immuno-nanoparticles were prepared for targeting invasive epithelial breast tumour cells. Monoclonal antibody (mAb) was used as a homing ligand and was attached to the nanoparticle surface either covalently or non-covalently. The presence of mAb on th...

BACKGROUND Autologous nerve grafts to bridge nerve gaps pose various drawbacks. Nerve tissue engineering to promote nerve regeneration using artificial neural conduits has emerged as a promising alternative. OBJECTIVES To develop an artificial nerve conduit using collagen-coated polylactic-glycolic acid (PLGA) and to analyse the survivability and propagating ability of the neuro-differentiate...

Aim: This study was aimed at evaluating the anticancer potential of curcumin-loaded poly(lactic-co-glycolic acid) (PLGA) based nanoparticles (NPs) in MDA-MB231 human breast cancer cells. Methods: Curcumin-loaded PLGA NPs were developed using a modified solvent evaporation technique. Physical characterization performed on formulated NPs. Furthermore, vitro experiments conducted to biological act...

The purpose of the present work was to develop hepatitis B surface antigen (HBsAg) surface-adsorbed cationic poly (d,l-lactic-co-glycolic acid) PLGA nanoparticles for interferon alpha (IFNα) delivery targeted to hepatocytes. Cationic PLGA nanoparticles loaded with IFNα were prepared using the double emulsification technique. Delipidated HBsAg was passively adsorbed on the surface of nanoparticl...

Objective(s): The present study was designed to evaluate of Metformin/Irinotecan-loaded poly-lactic-co-glycolic acid (PLGA) nanoparticles (NPs) effects on glutamate re-uptake time and receptor expression status in both glioblastoma multiforme (GBM) and cortex neuron cultures. The study was performed on glioblastoma cell line and primer cortex neuron.Materials and Methods: The re-uptake time and...

BACKGROUND Nanoparticles fabricated from the biodegradable and biocompatible polymer, polylactic-co-glycolic acid (PLGA), are the most intensively investigated polymers for drug delivery systems. The objective of this study was to explore fully the development of a PLGA nanoparticle drug delivery system for alternative preparation of a commercial formulation. In our nanoparticle fabrication, ou...

This study examines in vitro and in vivo biodegradation and biocompatibility of a thermogelling polymeric material, which we call a mixture hydrogel. The mixture contains two ABA-type triblock copolymers poly(d,l-lactic acid-co-glycolic acid)-b-poly(ethylene glycol)-b-poly(d,l-lactic acid-co-glycolic acid) (PLGA-PEG-PLGA) with different block ratios, and one polymer is soluble in water, but the...

Prediction of poly(lactic-co-glycolic acid) (PLGA) micro- and nanoparticles' dissolution rates plays a significant role in pharmaceutical and medical industries. The prediction of PLGA dissolution rate is crucial for drug manufacturing. Therefore, a model that predicts the PLGA dissolution rate could be beneficial. PLGA dissolution is influenced by numerous factors (features), and counting the ...
