mai exista cercetare in Romania
Nu reprezintă pentru nimeni o noutate faptul că – în România – cercetarea este codașă în lista de priorități a guvernanților, indiferent de coloratura lor politică. Cifrele brute vorbesc de la sine și nu lasă loc de nuanțe și interpretări. În acest context (vitreg), descoperirea cercetătorilor de la Institutul ”Victor Babeș” apare cu atât mai remarcabilă. Astfel, aceștia au descoperit un nou tip de celule, denumite telocite, celule care joacă un rol important în capacitatea de regenerare și reparare a țesuturilor și organelor din corpul omenesc, împreună cu celulele-stem.
Romanian researchers from “Victor Babes” National Institute for Research and Development in the Field of Pathology and Biomedical Sciences have discovered a cell type, which, together with stem cells could promote regeneration of heart muscle affected by stroke. Victor Babes Institute’s specialists have discovered by chance, while doing research on cells in the intestine, the presence of very small cells that help regenerate organs.
Santiago Ramón y Cajal discovered a particular cell type in the gut, which he named “interstitial neurons” more that 100 years ago. In the early 1970s, electron microscope (EM) studies showed that indeed a special interstitial cell type corresponding to the cells discovered by Cajal is localized in the gut muscle coat, but it became obvious that they were not neurons. Consequently, they were renamed “Interstitial Cells of Cajal”(ICC) and considered to be pace-makers for gut motility. For the past 10 years many groups were interested in whether or not ICC are present outside the gastrointestinal tract, and indeed, peculiar interstitial cells were found in: upper and lower urinary tracts, blood vessels, pancreas, male and female reproductive tracts, mammary gland, placenta, and, recently, in the heart as well as in the gut. Such cells, now mostly known as Interstitial Cajal-Like Cells (ICLC), were given different and confusing names. Moreover, ICLC are only apparently similar to canonical ICC. In fact, EM and cell cultures revealed very particular features of ICLC, which unequivocally distinguishes them from ICC and all other interstitial cells: the presence of 2–5 cell body prolongations that are very thin (less than 0.2 mm, under resolving power of light microscopy), extremely long (tens to hundreds of mm), with a moniliform aspect (many dilations along), as well as caveolae. Given the unique dimensions of these prolongations (very long and very thin) and to avoid further confusion with other interstitial cell types (e.g. fibroblast, fibrocyte, fibroblast-like cells, mesenchymal cells), was coined the term TELOCYTES for them, and TELOPODES for their prolongations, by using the Greek affix “telos”.
According to Laurenţiu Popescu, President of the Academy of Medical Sciences, the telocyte cells were highlighted by Romanian scholars and their existence was confirmed by independent teams from Italy, Germany, Britain and China. In tandem with stem cells, telocytes can help restore some vital organs like heart and brain.
“If we succeed to isolate, multiply them with stem cells, we can use effectively to treat heart attack,” said Professor Laurenţiu Popescu, M.D., Ph.D.
De aici. Cine vrea să cunoască mai multe despre istoria și detaliile descoperirii poate arunca o privire aici.
Lesne de înțeles, o finațare corespunzătoare a institutelor de cercetare care chiar produc rezultate științifice ar reprezenta o promovare mult mai bună pentru România, în loc de aruncat bani aiurea pe concerte și scene inutile marca Ridzi sau pe campanii de plagiat frunze marca Udrea & co. De pildă, comparați milionul de euro necesar Institutului ”Victor Babeș” cu sumele care se fură, cu acte în regulă, în România actuală…
PS Aflu că știrea nu este tocmai nouă, domnul Popescu acordând un interviu încă din luna aprilie revistei Viața Medicală, interviu în care acesta vorbește despre descoperirea telocitelor. Pesemne mass-media autohtonă nu a considerat subiectul destul de important pentru a fi strecurat în vreun jurnal de știri sau colț de tabloid, în cele patru luni scurse de atunci…
