Impactul rezultatelor asupra comunităţii<br />

ştiinţifice şi societate<br />

Prof. Dr. Virgil Păunescu a fost coordonator al echipei<br />

<strong>de</strong> imunologi care, împreună cu echipa Prof. Dr. Margit Şerban,<br />

a realizat primul transplant autolog (2001) şi primul<br />

transplant alogen (2002) <strong>de</strong> măduva osoasă din România. A<br />

fost promotor pe plan naţional al cercetării ştiinţifice cu<br />

privire la biologia celulelor stem şi potenţialul terapeutic în<br />

medicina regenerativă. A coordonat echipa din România implicată<br />

în proiectul integrat GENOSTEM care reprezintă<br />

unica participare românească în cadrul unui proiect integrat<br />

la competiţia FP6 pe domeniul „Life Sciences and Health”.<br />

Împreună cu Institutul <strong>de</strong> Boli Cardiovasculare Timişoara a<br />

realizat primul trial clinic privind aplicarea terapiei cu celule<br />

stem AC133 la pacienţii cu infarct miocardic (2003).<br />

Cercetările <strong>de</strong>sfăşurate pentru i<strong>de</strong>ntificarea unor surse alternative<br />

<strong>de</strong> celule producătoare <strong>de</strong> insulină ca terapie a diabetului<br />

zaharat au fost finalizate prin <strong>de</strong>punerea unui brevet<br />

<strong>de</strong> invenţie la US Patent (Brevet <strong>de</strong> invenţie nr.<br />

20060148079 - U.S. Patents: Isolation and purification of<br />

human insulin producing cells for the treatment of insulin<br />

<strong>de</strong>pen<strong>de</strong>nt diabetes). A organizat şi coordonat o echipa <strong>de</strong><br />

studii in vivo pe animal care a stat la baza iniţierii a o serie<br />

<strong>de</strong> mo<strong>de</strong>le experimentale animale. Rezultatele obţinute au<br />

fost publicate, şi a fost <strong>de</strong>pus un brevet <strong>de</strong> invenţie în acest<br />

sens („Aparat <strong>de</strong> respiraţie artificială pentru animale mici <strong>de</strong><br />

laborator (şobolan, cobai) cu un nou tip <strong>de</strong> valvă expiratorie”<br />

Nr. Înregistrare: A-00783-6.10.2006, OSIM Bucureşti).<br />

Colonie <strong>de</strong> celule stem mezenchimale pe suport tridimensional.<br />

Aplicarea unui colorant vital (acridin-orange/EtBr) indică<br />

instalarea apoptozei în zona centrală a coloniei.<br />

Colonies of mesenchymal stem cells on 3D scaffold.<br />

The vital staining (acridin-orange/EtBr) indicates<br />

the apoptosis in the central part of the colony<br />

The extected Impact of the Results<br />

on the Scientific Community and Society<br />

Prof. Dr. Virgil Paunescu coordinated the immunologists’<br />

team who performed in collaboration with the team<br />

coordinated by Prof. Dr. Margit Şerban, the first bone marrow<br />

autologous transplant (2001) and the first allogenic<br />

transplant (2002) in Romania. At national level he was the<br />

promoter of scientific research employing biology of stem<br />

cells and their therapeutic potential in regenerative medicine.<br />

He coordinated the Romanian research team involved<br />

in GENOSTEM integrated project, which represents the exclusive<br />

Romanian participation within an integrated research<br />

project in Frame Work Program 6 competition, ”Life Sciences<br />

and Health” priority. Together with Cardiovascular<br />

Diseases Institute in Timisoara, the first clinical trial on<br />

AC133 stem cells application in myocardial infarction<br />

(2003) was accomplished. The researches focused on i<strong>de</strong>ntification<br />

of alternative sources substituting the insulin producing<br />

cells as diabetes mellitus treatment conclu<strong>de</strong>d in a<br />

patent application at US Patent (US Patents no.<br />

20060148079: Isolation and purification of human insulin<br />

producing cells for the treatment of insulin <strong>de</strong>pen<strong>de</strong>nt diabetes).<br />

Prof. Dr. Virgil Paunescu organized and coordinated<br />

the research team working on animal mo<strong>de</strong>l experiments.<br />

The results were significant and published, and a patent application<br />

was granted (OSIM Bucuresti, no. A-00783-<br />

6.10.2006:”Artificial respiration <strong>de</strong>vice for small laboratory<br />

animals (rat, guinea pig) using a new expiratory valve”).<br />

Expresia alfa tubulinei în cultura <strong>de</strong> celule stem<br />

mezenchimale (imunofluorescenţă)<br />

Celule stem mezenchimale în mediu <strong>de</strong> diferenţiereosteoblastic.<br />

Se observă clustere <strong>de</strong> celule cu aspect modificat, poligonal<br />
