We present a protocol for efficient reprogramming of human somatic cells into human induced pluripotent stem cells (hiPSC) using retroviral vectors encoding Oct3/4, Sox2, Klf4 and c-myc (OSKM) and identification of correctly reprogrammed hiPSC by live staining with Tra-1-81 antibody.

Here we describe the first good manufacturing practice (GMP)-compliant method of producing virus-specific cytotoxic T lymphocytes (CTL) from umbilical cord blood, a source of predominantly naîve T cells.

T cells expressing a CD19-specific chimeric antigen receptor (CAR) are infused as investigational treatment of B-cell malignancies in our first-in-human gene therapy trials. We describe genetic modification of T cells using the Sleeping Beauty (SB) system to introduce CD19-specific CAR and selective propagation on designer CD19+ artificial antigen presenting cells.

Protocols for Assessing Radiofrequency Interactions with Gold Nanoparticles and Biological Systems for Non-invasive Hyperthermia Cancer Therapy

Stuart J. Corr^1,2, Brandon T. Cisneros^1,2, Leila Green¹, Mustafa Raoof¹, Steven A. Curley^1,3

¹Department of Surgical Oncology, University of Texas M.D. Anderson Cancer Center, ²Department of Chemistry, Rice University , ³Mechanical Engineering and Materials Science, Rice University

We describe the protocols used to investigate the interactions of 13.56 MHz radiofrequency (RF) electric-fields with gold nanoparticle colloids in both non-biological and biological systems (in vitro/vivo). These interactions are being investigated for applications in cancer therapy.

Synthesis of Immunotargeted Magneto-plasmonic Nanoclusters

Chun-Hsien Wu^1,2, Konstantin Sokolov^1,2

¹Department of Biomedical Engineering, University of Texas at Austin, ²Department of Imaging Physics, University of Texas M.D. Anderson Cancer Center

Here, we describe a protocol for synthesis of magneto-plasmonic nanoparticles with a strong magnetic moment and a strong near-infrared (NIR) absorbance. The protocol also includes antibody conjugation to the nanoparticles through the Fc moiety for various biomedical applications which require molecular specific targeting.

Automated Cell Enrichment of Cytomegalovirus-specific T cells for Clinical Applications using the Cytokine-capture System

Pappanaicken Kumaresan^*1, Mathew Figliola^*1, Judy S. Moyes¹, M. Helen Huls¹, Priti Tewari¹, Elizabeth J. Shpall², Richard Champlin², Laurence J.N. Cooper¹

¹Division of Pediatrics, U.T. MD Anderson Cancer Center, ²Stem Cell Transplantation and Cellular Therapy, U.T. MD Anderson Cancer Center

The goal of this protocol is to manufacture pathogen-specific clinical-grade T cells using a bench-top, automated, second generation cell enrichment device that incorporates a closed cytokine capture system and does not require dedicated staff or use of a GMP facility. The cytomegalovirus pp65-specific-T cells generated can be directly administered to patients.

¹Imaging Physics, University of Texas M.D. Anderson Cancer Center, ²Advanced Imaging Research Center, University of Texas Southwestern Medical Center

A multi-compartment dynamic phantom is used to simulate some biology of interest for metabolic studies using hyperpolarized magnet resonance agents.

This protocol describes the application of combined near-infrared fluorescent (NIRF) imaging and micro-computed tomography (microCT) for visualizing cerebral thromboemboli. This technique allows the quantification of thrombus burden and evolution. The NIRF imaging technique visualizes fluorescently labeled thrombus in excised brain, while the microCT technique visualizes thrombus inside living animals using gold-nanoparticles.
