La tecnologia delle cellule staminali hanno causato un notevole entusiasmo tra gli interessati alla salute degli animali e degli uomini. Molte persone stanno cercando nuove cure per le malattie e la terapia i vivo. Noi sappiamo che tutti i tipi di cellule possono essere rigenerate eccetto le cellule neuronali di mammifero, sebbene il tessuto nervoso periferico si rigeneri la guaina mielinica che permette l’orientamento della fibra. L’importanza di ottenere cellule neuronali funzionali è vitale per le malattie neurodegenerative. Le malattie neurodegenerative sono per definizione delle malattie progressive corniche caratterizzate da una selettiva perdita di neuroni in aree motori simmetriche, sensoriali e cognitive appartenenti al SNC, o perdita/ disfunzione delle fibre mieliniche o non mieliniche nel SNP. Oggi è possibile deprogrammare cellule adulte in cellule staminali pluripotenti in vitro utilizzando specifici protocolli e sostanze non tossiche per l’uomo, ottenere neurosfere (corpi cellulari da dove è possibile isolare e studiare le cellule staminali neuronali). In questo lavoro di tesi ho dimostrato come è possibile utilizzando cellule deprogrammate del sangue ottenere neurosfere e differenziarle in neuroni adulti in vitro e come questi miei risultati siano in accordo con i risultati ottenuti in vivo.

Abstract
Stem cells technology has provoked considerable excitement among people interested in welfare of animals and humans. Many people are searching for new treatments of diseases and in vivo therapy. We know that all types of cells can be regenerated except neural cells of mammals such as don’t regenerate, although the peripheral nervous tissue regenerate if neurillematic sheath allow the orientation of fiber. the importance of obtaining functional nerve cells is vital in neurodegenerative diseases. Neurodegenerative diseases are by definition progressive chronic diseases characterized by a selective loss of neurons in areas, symmetric motor , sensory , cognitive and member ship of CNS, or loss / dysfunction of myelinated or non myelinated fibers in the PNS. It has been possible today to use BDSCs after Deprogrammation of adult peripheral blood, and using specific protocols to obtain “neurospheres” from these cells in specific medium and non toxic substances addition. Neurospheres (composed of neural stem cells) provide a method for investigating neural precursor in vitro instead of embryonic stem cells. In this study I have demonstrated how BDSCs being able to form neurospheres and differentiated into mature neurons in vitro, and how it is possible to use stem cells therapy as treatment in vivo.File | Dimensione | Formato | |
