The project takes part in Subprogramme S1 «Fundamental and pre-competitive research» having as general objects: stimulation of high performance scientific activity in the field of the biomedical sciences, of consolidation of a research team previously constituted in the frame of a World Bank project, of increase of the Romanian science visibility and of promotion of the international collaborations.
The specific objectiv of the project:
«Advanced researches at the cellular and molecular level of a fundamental biologic process – the maintenance of the human tegument homeostasis».
The precise objectives of the project:
1. Realization of some experimental models for study of wound repair;
2. Comparative studies to choice an optimal model for research of the molecular mechanisms involved in skin lesion repair;
3. Simulation of some lesions on the chosen experimental model and study of the induced morphological and biochemical changes;
4. Estimation of the dynamics of cell – matrix interactions during the lesion repair.
Activities for fulfilment of the project objectives:
1. Obtaining of keratinocyte cultures from human epidermis, in monolayer and in the presence of some cell matrix components;
2. Obtaining of fibroblast cultures from human dermis, in monolayer and in the presence of some cell matrix components;
3. Obtaining of a keratinocyte-fibroblast co-culture;
4. Comparative studies on cell morphology, viability and proliferation;
5. Estimation of the reproduction grade of differentiation markers and of the keratinocyte growth stopping;
6. Study of the action of some compounds with hyperproliferative effect;
7. Realization of mechanical, hyperthermic and oxidant lesions, by gamma irradiation, exposure to irritant substances; estimation of morphologic changes induced by lesions, estimation of some pro-inflammatory cytokines, study of the post-lesional evolution of some matrix metalloproteinases;
8. Study of the efficiency of some compound’s action: insulin, hydrocortisone and vitamin A upon the lesion repair.
