Ongoing research projects
1) Human neural stem cells as an in vitro model to assess neurodegeneration caused by DNA damage response defects
Early progressive neurodegeneration is prominent feature of hereditary syndromes attributable to mutations in DNA damage response/repair (DDR) genes. Ataxia telangiectasia (A-T), A-T like disease (A-TLD) and Nijmegen breakage syndrome (NBS) are related neurodegenerative entities caused by mutations in ATM, MRE11 and NBS1 genes, respectively, whose encoded proteins function together in the DDR. Besides the accumulation of DNA damage as a mechanism for neurodegeneration, other factors including oxidative stress and oxidative DNA damage, mitochondrial dysfunction, unscheduled re-entry into cell cycle, have been variably implicated, at least in animal models. Whether similar mechanisms occur in human neural cells is unclear, due to the lack of appropriate model systems.
Taking advantage of normal human neural stem cells (hNSCs) possessing in vitro self-renewal and differentiation potential into neurons, astrocytes and oligodendrocytes, we aim to investigate the consequences of ATM, Nbs1 and Mre11 knockdown on neuronal cell fate, with a major focus on DNA damage mechanisms and interplay with intracellular oxidative stress, oxidative DNA damage and mitochondrial dysfunction.

2) The generation of induced pluripotent stem cells from adult mesenchymal stem cells and analysis of their genomic stability
We propose that the frequency of derivation of iPS cells may be greater if the cell being reprogrammed is an adult stem cell. Therefore, the overall aim of this project is to test the hypothesis that iPS cells can be generated with higher frequency from human adult mesenchymal stem cells (hMSCs) than from human dermal (skin) fibroblasts. Once iPS cells are established we will characterise their genomic stability and capacity for DNA repair. The specific scientific objectives are:
1. To compare the efficiency of derivation of iPS cells from adult human MSCs versus dermal fibroblasts.
2. To analyse the genomic stability and DNA damage responses in iPS cells generated from hMSCs.
3. To produce iPS cells from Ataxia Telangiectasia patients. This would represent a novel cellular model of the disease, suitable for studying both the neurodegenerative events and the other cellular phenotypes of AT patients.

3) Piattaforma ACTIVE – Advanced Cardiovascular Therapies
Il progetto ACTIVE è un progetto che mira a costituire una piattaforma tecnologica multidisciplinare orientata allo sviluppo di prodotti innovativi ad alto contenuto di ricerca industriale nell’ambito della “tecnologia biomedicale avanzata per la terapia cardiovascolare”.
Obiettivi scientifici e tecnologici
L’obiettivo scientifico e tecnologico è dunque duplice e mira allo sviluppo di:
1. Un nuovo stent a rilascio di farmaco multiplo combinato a supporto della terapia vascolare di angioplastica.
2. Una matrice di materiale bioartificiale bioinduttivo (Biomatrice) e relativo metodo di posizionamento (delivery system sia per intervento chirurgico tradizionale e MIS che percutaneo) allo scopo di guidare la formazione e rigenerazione di tessuto autologo nella parte infartuata del miocardio.


4) Bio-Nano-Tecnologie per la medicina rigenerativa: nanoparticelle fluorescenti funzionalizzate per l’imaging innovativo di cellule staminali mesenchimali umane
Il progetto è un approccio multidisciplinare orientato allo sviluppo di prodotti high-tech per imaging ad alto contenuto di ricerca applicata e trasferimento tecnologico.
Sono obiettivi del presente progetto:
1. la produzione di bio-nanomateriali innovativi per imaging molecolare in fluorescenza di cellule staminali, utili ad evidenziarne la crescita e il differenziamento in vitro e in vivo, che superino le limitazioni sopra riportate
2. la realizzazione prototipale di un microscopio a due fotoni dotato di OPO (optical parametric oscillator), in grado di visualizzare in 4D (3 dimensioni spaziali più temporale) cellule staminali marcate con questi bio-nanomateriali
3. la produzione di protocolli ottimizzati per l’imaging di cellule staminali mesenchimali umane, le cellule maggiormente utilizzate in medicina rigenerativa, utilizzando i prodotti sopra descritti.
