Plasticidade de células tronco mesenquimais de medula óssea de ratos na presença de meio condicionado do nervo facial e do fator de crescimento fibroblástico 2

A number of evidences show the influence of the growth of injured nerve fibers in Peripheral Nervous System (PNS) as well as potential implant stem cells (SCs) to make it more suitable for nerve regeneration medium. In this perspective, this study aimed to evaluate the plasticity of mesenchymal stem cells from bone marrow of mice in the presence of culture medium conditioned with facial nerve explants (D-10) and fibroblast growth factor-2 (FGF-2). In this perspective, the cells were cultivated only with DMEM (group 1), only with D-10(group 2), only with FGF-2(group 3) or with D-10 and FGF-2(group 4). The growth and morphology were assessed over 72 hours. Quantitative phenotypic analysis was taken from the immunocytochemistry for GFAP, OX-42, MAP-2, β-tubulin III, NeuN and NF-200 on the fourth day of cultivation. Cells cultured with conditioned medium alone or combined with FGF-2 showed distinct morphological features similar apparent at certain times with neurons and glial cells and a significant proliferative activity in groups 2 and 4 throughout the days. Cells cultived only with conditioned medium acquired a glial phenotype. Cells cultured with FGF-2 and conditioned medium expressed GFAP, OX-42, MAP-2, β-tubulin III, NeuN and NF-200. On average, area and perimeter fo the group of cells positive for GFAP and the área of the cells immunostained for OX-42 were higher than those of the group 4. This study enabled the plasticity of mesenchymal cells (MCs) in neuronal and glial nineage and opened prospects for the search with cell therapy and transdifferentiation

A auto-estima da criança que sofre violência física pela família

This research investigates the self-esteem of children who suffered physical violence by family members. Seven children took part in the research: three boys and four girls, aged between six and twelve years old. The analysis were done from the constructed data obtained from: semi-structured interview, activities about human feelings, activities that included facial expressions, unfinished phrases, Pinocchio s story, a drawing of a family and a drawing of their own family. Data were analyzed from the Content Analysis. The Thematic Units were: violence, intrafamily violence, and self-esteem. The synthesis of the categories studied evidenced that the physical violence and the psychological violence present in the lives of children affect the positive development of their self-concept and, consequently, of their self-esteem. Among the results, we emphasize some negative feelings that are present in children s lives such as fear, a sense of guilt, and sadness, arising out of the situations of violence they have experienced
