Gene Delivery by Immobilization to Cell-Adhesive Substrates

Micropatterned dynamically adhesive substrates for cell migration.

We present a novel approach to examine cell migration using dynamically adhesive substrates consisting of three spatially and functionally distinct regions: the first is permanently nonadhesive to cells, the second is permanently adhesive, and the final region is electrochemically switched from nonadhesive to adhesive. We applied a double microcontact printing approach to pattern gold surfaces ...

Gene Delivery to Mesenchymal Stem Cells

There is increasing trend in using recombinant stem cells as novel therapeutic candidates in different diseases. These studies encompass different applications from targeted homing of Mesenchymal Stromal (stem) Cells (MSC), to arming them with different cytokines. Resistance to transfection or transduction methods had urged researchers to look for better gene delivery alternates and optimizing ...

Modeling of Cell Motion on Patterned Adhesive and Deformable Substrates

Investigating lipopolymers based on polyethylenimine and nanoliposome for gene delivery to prostate cancer (PC3) cell line

Background: Non-viral Nano carriers such as liposomes and cationic polymers based on engineered properties are regarded in gene delivery field. Although these carriers do not have weaknesses of viral vectors, but they are less efficient than viruses and they still need to be improved as favorable gene delivery carriers. Amongst non-viral carriers, cationic liposomes have been proposed for clini...

Recombinant mussel adhesive protein as a gene delivery material.

Efficient target gene delivery into eukaryotic cells is important for biotechnological research and gene therapy. Gene delivery based on proteins, including histones, has recently emerged as a powerful non-viral DNA transfer technique. Here, we investigated the potential use of a recombinant mussel adhesive protein, hybrid fp-151, as a gene delivery material, in view of its similar basic amino ...
