Overview of Services
The Translational Pathology Shared Resource at the University of Arkansas for Medical Sciences is comprised of the Experimental Pathology Core and the Tissue Biorepository and Procurement Service (TBAPS).
The UAMS Experimental Pathology (ExPath) Core Laboratory provides researchers with centralized, comprehensive histological services. The laboratory can process and paraffin embed tissues, and section frozen and paraffin-embedded tissues for use in biochemical, molecular, and pathologic studies. The laboratory works with investigators to develop immunostaining approaches to detect specific targets of interest, and to identify clinical pathologists who can assist with image analysis and data interpretation.
The UAMS Tissue Biorepository and Procurement Service (TBAPS) is a repository of human specimens accessible to the UAMS research community. TBAPS uses an IRB approved protocol and general consent form to consent patients, acquire samples from the pathology grossing room, and provide samples to researchers who have appropriate approval. Solid tissues and fluid specimens are stored in liquid nitrogen tanks. Solid tissues may also be embedded into paraffin. De-identified sample and related pathology data are available for a variety of organs.

Equipment
Experimental Pathology
Processing: Tissue-Tek VIP E300 Tissue Processor
Embedding: Tissue-Tek Embedding Center
Sectioning: Microm HM505E Cryostat, Microm HM325 Rotary Microtome
Staining: Histo-Tek SL Automated Slide Stainer, Tissue-Tek Glas Automated Glass Coverslipper, Leica Bond-Rx Fully Automated Research Stainer
Imaging: Digital imaging and analysis of slides are available using an Aperio Scanscope CS coupled with ImageScope Slide Viewer and Image Analysis software from Leica. Available analysis algorithms include color deconvolution, nuclear and membrane localization, and quantifying positive pixel number and intensity
Phenoptics™ analysis is available using the Mantra™ Quantitative Pathology Workstation, which is a manual microscope equipped with a multispectral camera and inForm® image analysis software. Phenoptics integrates multiplexed immunohistochemistry and imaging to quantitatively capture systems biology data with cellular detail. It reveals multi-parameter cellular expressions and interactions while retaining spatial context, offering insights into the complexity of tissue biology.
