Neurogeneze a gliogeneze v dospělém mozku po ischemickém poškození
Honsa, Pavel ; Anděrová, Miroslava (advisor) ; Vyklický, Ladislav (referee) ; Mazurová, Yvona (referee)
Ischemic brain injury belongs to the most common cause of death in the developed countries. High complexity of this disorder significantly slows and limits the possible treatment. Currently, there is only one treatment available - the application of the thrombolytic, tissue plasminogen activator, while thousands of other drugs failed during clinical testing. Great expectations were seen in the stroke treatment employing neural stem cells obtained from several external sources; nevertheless, low survival rate, limited favorable outcome and enormous ethical issues complicate the application of such therapy. On the other hand, in the adult mammalian brain exist two endogenous processes - neurogenesis and gliogenesis. These processes need to be fully described and understood, in order to employ them as a source of new cells after injury. Therefore, this thesis focuses on the processes of adult neurogenesis and gliogenesis predominantly after ischemia. Adult neurogenesis and gliogenesis are processes, by which neurons or glial cells are generated from stem/progenitor cells. Both these processes are strongly influenced by brain injury; nevertheless, their contribution to regeneration after ischemia in the human brain is negligible. Here, we aimed to describe the role of polydendrocytes in the...
