Anti-inflammatory compounds and stem cells in treatment of spinal cord injury
Kárová, Kristýna ; Jendelová, Pavla (advisor) ; Sameš, Martin (referee) ; Chvátal, Alexandr (referee)
Despite intense scientific efforts, spinal cord injury (SCI) remains to be a severe neurological condition that has no treatment. Currently, therapy is based on alleviating pressure by surgical spinal cord decompression, administration of methylprednisolone and physical therapy. In this study, therapeutic effects of anti-inflammatory compounds and of three types of stem cells were tested in a balloon compression model of spinal cord injury in rats. Natural compounds epigallocatechin-3-gallate (EGCG) or curcumin were administered in situ and then intraperitoneally every day for up to 28 days. Human bone marrow mesenchymal stem cells (MSCs), human spinal neural precursors (SPC-01) and neural precursors derived from human induced pluripotent stem cells (iPS-NPs) were transplanted intrathecally (MSCs) or via spinal injection into immunosuppressed rats 7 days after induction of SCI. To determine effects of therapies, changes in motor function was tested by open field test BBB, flat beam test and score, Plantar test and rotarod. Morphometric analysis was used to assess gray/matter sparing and cavity size. Immunohistochemistry was used to determine survival and differentiation of transplanted cells, activation of classical pathway of NFκB (p65 nuclear translocation), astroglial activation (GFAP) and...
: Investigation of lymphocyte populations in the porcine small intestine
Kárová, Kristýna ; Šinkora, Marek (advisor) ; Javorková, Eliška (referee)
8 ABSTRACT Historically pig is allocated to a group of animals which use certain parts of their small intestine to acquire a fully developed primary B cell reperoire. Development of such primary repertoire is independent on the antigen presence and resembles the primary lymphopoietic activity of avian bursa of Fabricius. However, some findings concernig the pig's alignment in the above mentioned group suggest otherwise. This graduation thesis is focused on the investigtion of lymphocyte populations and subpopulations in the small intestine of germ-free and conventional piglets. The aim is to determine whether the percentage amounts of lymphocyte populations is dependent on the intestinal colonization. Using Flow Cytometry the significant differences between individual samples were assesed allowing us to conclude which parts of the small intestine could possibly be used for the development of B cell repertoire. Moreover, the status of isotype switching of B lymphocytes isolated from different intestinal parts was determined by the means of PCR analysis. Our data suggest that the small intestine colonization has a crucial role in development of all the main lymphocyte populations as well as some of their subpopulations. The greatest influence of colonization was observed concerning B lymphocytes and their...
