Gene Delivery and Transfection Studies with Lipopolyplexes in Human Endothelial and Smooth Muscle Cells

Brito L., Little S., Langer R., Amiji M., Northeastern University, US

Non-viral gene delivery and transfection in primary human vascular endothelial cells (EC) and smooth muscle cells (SMC) has tremendous potential for cardiovascular diseases, such as in treatment of coronary restenosis. Using a combination of synthetic [...]

Enhancement of in vitro Capillary Tube Formation by Substrate Nanotopography

Bettinger C.J., Zhang Z., Gerecht S., Borenstein J.T., Langer R., Massachusetts Institute of Technology, US

Controlling the morphology and function of cells using substrate nanotopography is a phenomenon that can be utilized in a variety of fields including tissue engineering and regenerative medicine. In this work, we explored the possibility [...]

Targeted Aptamer-Nanoparticles to Diminish Drug Resistance of Cancer Cells in vitro Study

Basto P., Alexis F., Levy-Nissenbaum E., Langer R., Farokzhad O., Massachusetts Institute of Technology, US

Using prostate cancer as a model, we report the drug release of pacitaxel and doxorubicin from aptamer-poly (D,L lactic co glycolic acid)-poly(ethylene glycol) (PLGA-PEG) nanoparticles used to target prostate-specific membrane antigen (PSMA), a well characterized [...]

Targeted Nanoparticle-Polypeptide Conjugates for Breast Cancer Treatment

Alexis F., Basto P., Radovic-Moreno A., Langer R., Farokhzad O.C., Brigham and Women's Hospital, Harvard Medical School, US

We have developed a polymeric targeted nanoparticle-polypeptide conjugates that shows cell binding speficity and stealth properties. The targeted naoparticles binds and are taken up efficiently by Her2 expressing breast cancer cells. These nanoparticles represent a [...]
