Using cationic polyurethane-short branch PEI as microRNA-driven nano-delivery system for stem cell differentiation

Optimization of conditions for gene delivery system based on PEI

Objective(s): PEI based nanoparticle (NP) due to dual capabilities of proton sponge and DNA binding is known as powerful tool for nucleic acid delivery to cells. However, serious cytotoxicity and complicated conditions, which govern NPs properties and its interactions with cells practically, hindered achievement to high transfection efficiency. Here, we have tried to optimize the properties of ...

PLLA/HA Nano composite scaffolds for stem cell proliferation and differentiation in tissue engineering

Abstract Due to their mulitpotency, Mesenchymal stem cells (MSCs), have the ability to proliferate and differentiate into multiple mesodermal tissues. The aim of this study was to isolate MSCs from human Umbilical Cord (hUCMSCs) to determine their osteogenic potential on nanofibrous scaffolds. To this end, Poly (L-lactic acid) (PLLA)/Nano hydroxyapatite (HA) composite nanofibrous scaffolds were...

Methodology Report Nonviral Gene Delivery toMesenchymal Stem Cells Using Cationic Liposomes for Gene and Cell Therapy

Mesenchymal stem cells (MSCs) hold a great promise for application in several therapies due to their unique biological characteristics. In order to harness their full potential in cell-or gene-based therapies it might be advantageous to enhance some of their features through gene delivery strategies. Accordingly, we are interested in developing an efficient and safe methodology to genetically e...
