Hudock1, Deepak Kaushal1,2 1Bacteriology and Parasitology, Tulane National Primate Research Center, 2Microbiology and Immunology, Tulane National Primate Research Center Microdissection has been extensively employed for the examination of DNA, RNA, and protein within tissue. Laser capture microscopy (LCM) is the most commonly used method, but a new milling technique, mesodissection, is recently available. We demonstrate RNA extraction from mesodissected formalin fixed paraffin embedded tissue slides of Mycobacterium tuberculosis granulomas. Bioengineering Nonhuman Primate Lung Decellularization and Recellularization Using a Specialized Large-organ Bioreactor Ryan W. Bonvillain1,2, Michelle E. Scarritt1, Nicholas C. Pashos1, Jacques P.

The description of a nonhuman primate model of lung regeneration in which whole lungs are decellularized and then seeded with adult stem cells and endothelial cells in a bioreactor that facilitates vascular circulation and liquid media ventilation is presented.
