Abstract
Il trattamento delle malattie neurologiche del Sistema Nervoso Centrale costituisce una delle maggiori sfide aperte dalla ricerca biomedica. In questo ambito, la terapia cellulare, cioe' la sostituzione delle cellule danneggiate con nuove cellule, si colloca tra le strategie piu' affascinanti e ricche di promesse per il trattamento di lesioni cerebrali e delle malattie neurodegenerative. Questi entusiasmi si basano sull'identificazione e sull'isolamento di cellule staminali neurali e sulla dimostrazione della loro capacità di integrarsi in diversi tessuti, acquisendo fenotipi specifici. Tuttavia, sono ancora molti i quesiti che devono essere risolti prima che questa strategia sia applicata con successo ed efficacia alle malattie neurologiche. Tra i piu' importanti vi sono l'analisi del reale potenziale differenziativo delle cellule staminali e progenitori neurali e, d'altra parte, la capacità dell'ambiente ospite di esprimere segnali capaci di dirigerne l'integrazione. Per risolvere questi problemi è necessario chiarire i meccanismi cellulari e molecolari che regolano la proliferazione, la specificazione ed il differenziamento di cellule staminali neurali endogene o dopo trapianto nel sistema nervoso centrale.

Affrontare problematiche biologiche cosi' complesse richiede tecnologie e approcci differenti. La creazione di un network multidisciplinare come quello proposto rappresenta dunque un requisito essenziale, oltre ad una potenzialita' propositiva e di>>>

Le terapie di sostituzione cellulare rappresentano uno dei più promettenti sviluppi nella ricerca di nuovi trattamenti per le lesioni cerebrali e le patologie neuroedgenerative. Il razionale di questo approccio terapeutico prevede il trapianto nel sistema nervoso centrale di cellule che siano in grado di sostituire gli elementi degenerati e ricostituire le connessioni interrotte, ripristinando la normale funzione cerebrale. Dato che i neuroni adulti non sopravvivono alle procedure di dissezione e trapianto, è necessario utilizzare come elementi donatori cellule proliferanti indifferenziate, che, una volta immesse nell'ambiente ospite, siano in grado di acquisire specifici fenotipi maturi. L'utilizzazione di cellule fetali in modelli animali ha permesso di dimostrare come i trapianti neurali permettano di riparare i danni anatomici e ridurre i deficit funzionali conseguenti a diversi tipi di lesione o degenerazione nervosa. Sulla base di questi risultati sono stati condotti trials clinici su pazienti affetti da diverse patologie neurologiche, come il morbo di Parkinson, la malattia di Huntington o l'ictus cerebrale (Björklund e & Lindvall, 2000). Tuttavia, nonostante i promettenti risultati ottentuti da questi sperimentazioni, l'uso delle cellule fetali pone notevoli problemi etici e metodologici che di fatto rallentano il pieno sviluppo di questa strategia terapeutica.
La scoperta delle cellule staminali neurali (CSN) ha aperto nuove prospettive nella ricerca di una>>>
