The Shared Resources of the Dan L. Duncan Comprehensive Cancer Center provide technical support services essential for basic and clinical research studies of Cancer Center members. The NCI-designated Cancer Center Support Grant provides funding support for advanced technologies, high-end instrumentation, data analysis, biostatistics and informatics services that would be difficult and too expensive for individual investigators or programs to develop and maintain on their own. Below are short descriptions of the Shared Resources with links to websites with more detailed information.
Advanced In Vivo Cancer Models Shared Resource
Leader: Michael Lewis, Ph.D.
Co-Leaders: Hugo Villanueva, Ph.D., Jianming Xu, Ph.D. and Jason D. Heaney, Ph.D.
The Advanced In Vivo Cancer Models Shared Resource is constructed to meet the needs of Cancer Center investigators wishing to use experimentally demanding, state-of-the-art, in vivo cancer models that require specialized techniques, and a high degree of experimental ingenuity. These models include genetically engineered mice (“knockout,” “knockin,” and transgenics), and patient-derived tumor xenografts (PDX) grown either in immunocompromised mice, or in alternative platforms such as the chicken egg chorioallantoic membrane (CAM). Both mouse and human-derived models require substantial validation work to “credential” that they are reflective of the biology of the disease or process under study. Since patient-derived tissues used to generate the models have considerable associated clinical and “omic” information, computational infrastructure is supported to abstract, store, organize, retrieve, and display such information so that investigators can make rational choices as to which model(s) to use, and to help interpret their results. AICM is a merger and restructuring of Genetic Engineered Mouse (GEM) and Patient-Derived Xenograft and Advanced In Vivo Models (PDX-AIM) Shared Resources supported by Baylor College of Medicine and the DLDCCC. For more information, visit the GERM and PDX-AIM web sites.
Advanced Microscopy and Image Informatics Shared Resource
Leader: Michael Mancini, Ph.D.
Co-Leader: Fabio Stossi, Ph.D.
The Advanced Microscopy and Image Informatics Shared Resource provides high quality microscopy and analytics services to DLDCCC members through availability of state-of-the-art imaging instrumentation, custom image analysis, one-on-one training by expert staff, plus consultation for experimental setup, data acquisition and analysis. AMII covers most of investigators needs for light microscopy with particular emphasis on fully-assisted services for super-resolution microscopy, high throughput/high content imaging-based phenotypic or mechanistic screening, assay development, live imaging, multi-dimensional spatial analysis, imaging of 3D culture models and custom image analysis pipelines and data analytics. AMII is also invested in education and training through graduate level teaching, symposia and seminar organization, and via one-on-one training for most of the services. The original Integrated Microscopy Core was renamed AMII to highlight enhanced capabilities in super-resolution, live imaging, and high throughput microscopy coupled with image analysis.

Cell Processing and Vector Production Shared Resource
Leader: Natalia Lapteva, Ph.D.
Co-Leader: Zhuyong, Mei, Ph.D.
The Cell Processing and Vector Production Shared Resource provides manufacturing of therapeutic grade cellular therapy products and viral vector for use in early phase clinical trials. These must be prepared according to current Good Manufacturing Practices as mandated by the Food and Drug Administration. This CPVP provides the infrastructure and environment to prepare, test, and release these products for use. It consists of a state-of-the-art facility with 22 manufacturing clean rooms and support facilities and highly experienced manufacturing and quality control and assurance staff. This Shared Resource works with investigators to develop clinical scale manufacturing procedures, and release test specifications, testing procedures, quality assurance oversight, and regulatory assistance for IND submissions. The CPVP facilitates the transition of cellular and gene therapy products from the basic science laboratories into early-phase clinical trials. The CPVP currently supports more than 50 clinical trials (21 actively accruing, 18 in follow-up, and 11 in stages of translation to investigational new drug applications [INDs]) held by DLDCCC investigators and does so at a much-reduced cost compared to commercial manufacturing and testing entities. For more information, visit the Cell Processing and Vector Production Shared Resource web site.
Gene Modulation in Cancer Cell Models Shared Resource
