CellDiff - Introduction  Last update: 090824


 
This introduction is aimed to inform readers about the Center of Excellence in the Physiopathology of Cell Differentiation,  in brief CellDiff, at the Vita-Salute San Raffaele University of Milan: who we are, when and why we were established, what has happened in the meantime in terms of scientists  joining or leaving, of scientific productivity, of prestige of the Center.  At the end we will also present our general opinion about Centers of Excellence and about the role they could play in our Country.

Centers of Excellence in Italy
CellDiff was established in 2001 by the Italian Ministry of University and Research (MIUR), together with other  44 Centers of Excellence active in all areas of knowledge: not only in sciences (including physics, chemistry, biology and biomedicine) but also in various humanities. These Centers were the first, and so far remain the only examples of Institutions of this type established in Italy. Needless to say,  in other European countries Centers of Excellence are numerous and well appreciated. The Italian Centers were established and funded for 3 years, with the idea that later on they would have continued to operate with external funds. No evaluation of their work by external scientist reviewers has ever been made. Therefore, the present state of the many Centers is unknown.

CellDiff  and its Staff
At its beginning CellDiff included 9 research groups of the San Raffaele Medical School, working in various areas of Biomedicine and interested in Cell Differentiation, together with a few associated groups of adjacent Universities, such as the University of Milan and that of the Oriental Piedmont. In addition, many scientists belonging not to the University but to the San Raffaele Institute, did participate and, in some cases,  even led the research work. The close synergy between the two Institutions is in fact a stable property of our work, a critical aspect of the scientific success of the “San Raffaele” model. During the years the staff of CellDiff has changed somewhat. A few colleagues have stepped down for various reasons and some have joined the Center, mostly upon their move to the University staff. At the moment the groups are  11, specified by the name of their PIs that appear on the front page of this web site. 

The Research
The CellDiff groups were all of high scientific level  and their collaboration assured a considerable degree of interdisciplinary research. The funds that were received by the Center from the MIUR (as a whole  1.780 million it. Lira, corresponding to less than 1 million €) were all invested in the updating of advanced techniques of general importance for our research, while the work of each group has been entirely supported by external grants, obtained from public and private sources, of Italian and international origin (all together, in the last 8 years, over 20 million €).  As documented by the 410 articles appeared from 2002 in the international scientific literature, the groups have worked with no interruption. Even more important, most of their articles have appeared in highly prestigious Journals, including those advertized in the press, such as Nature and Science, as well as the top specialized Journals of specific scientific areas, including Cancer, Immunology and Neuroscience.  In terms of Impact Factor (the index  that reveals the of impact of  Journals in the scientific community)  the performance of the Center is impressive: overall impact, 2656; average impact/single publication,  6.5). These numbers confirm that all our PIs are leaders in their field at the international level.

Training of Young Scientists and Translational Activities
At CellDiff, training of young scientists is strictly integrated with the research activity. Three levels are considered. University students are accepted in the laboratories before and after their “Magistral thesis”, i.e. just at the beginning of a scientific activity. About 10% of the candidates, after a very competitive examination, are accepted in the International PhD schools in Molecular an Cellular Biology and Molecular Medicine, which are coordinated by Members of the CellDiff staff and run according to the most advanced criteria, including 9 month stages of the students in prestigious foreign laboratories. Finally, CellDiff laboratories are among the few in Italy to include post-docs and Professors in sabbatical, coming from EU countries and North America, mostly supported by international fellowships. This, and the seminars and lectures, all given in English, contribute substantially to the international atmosphere of our research.
The CellDiff scientists are greatly interested in translational research. Most of their work is in fact in areas of medical interest, often carried out in collaboration with clinicians of the San Raffaele Hospital. In addition, various patents, based on the results produced by the CellDiff scientists,  have been granted and are now attracting considerable interest. Finally, CellDiff staff scientists collaborate with biotec Companies, in particular with MolMed, the spin-off company born in the San Raffaele Institute, since a few years a publicly traded Company.

Four Letters of Opinion
In order to obtain an independent evaluation of our work  we have asked four colleagues of the highest prestige to write down letters of opinion about the work made by the CellDiff scientists during the years: Günter Blobel and Erwin Neher, two Nobel laureates; Kai Simons, the Founder of the European Life Scientist Organization, ELSO ; and Pietro De Camilli, a brilliant Italian Researcher who leads Neurobiology at the Yale University. Have a look at the letters that these colleagues have written, which appear in this web site. They summarize our work much better than any long presentation.

Are Centers of Excellence needed in Italy?
Finally, what might be the general significance of CellDiff and other Centers of Excellence in Italy? As specifically emphasized by our prestigious colleagues in their letters of opinion, these institutions play critical roles in the progress of research in most advanced Countries. These foreign Centers are not only established more often, with much larger economical support and for longer periods of time than in Italy, but in addition they are systematically evaluated for their scientific work. A serious evaluation, based not only on bureaucratic, but especially on scientific criteria, carried out by highly qualified committees including foreign experts of the field, is critical for the life of Centers. In fact, if the Center is approved,  the evaluation warrants that research keeps going, possibly improving its level, deserving further support and stimulating its synergy with other experiences; if the Center is turned down, the evaluation opens chances for new Centers to be approved without further expenses. At a time when, even in Italy, excellence of Universities is being more and more requested, especially in the field of  research, the re-establishment, strengthening and systematic evaluation of  Centers of Excellence appear therefore as operational and cultural tools, profoundly needed for the scientific and economic progress of our Country.
