Perikardial Sıvıdan İzole Edilen Hücrelere Fibroblast Büyüme Faktörü (FGF-2) Etkisinin Analizi

Perikardiyal sıvı (PF) heterojen bir hücre topluluğuna sahiptir. Bu hücrelerden biri de mezenkimal kökhücre özelliği taşıyarak başka hücrelere farklılaşma potansiyeline sahip olan mesotelyal hücrelerdir. Buhücrelerin sayısı doku hasarıyla birlikte artarak büyüme faktörleri (VEGF, FGF-2, PDGF, TGF-b) veekstrasellüler matriks (ECM) moleküllerini sentezleyerek doku/organda meydana gelen hasarınonarımında önemli bir yer tutmaktadır. Bu çalışmada mesotelyal hücrelerin hücre kültür ortamına FGF-2(basic fibroblast growth factor)’ nin eklenmesiyle mesotelyal hücrelerin vasküler doku oluşumuna etkisiincelenmiştir. Bu amaçla büyüme faktörü eklenmiş ve büyüme faktörü eklenmemiş olan kontrol grubuhücrelerinin birinci ve beşinci günlerdeki ışık mikroskobu görüntüleri kullanılarak analiz edilmiştir. Bugörüntüler ve görüntü histogramları kullanılarak Hjorth parametreleri olan mobilite, aktivite vekomplekslik özellikleri, çarpıklık, basıklık ve entropi değerleri kullanılarak istatistiksel olarak analizedilmiştir. Birinci ve beşinci günlerde FGF-2 eklenen ve eklenmeyen kültürdeki hücreleringörüntülerinden hesaplanan özniteliklerin gruplar arasındaki farklılığı değerlendirmek için istatistikselanalizi yapılmıştır. Elde edilen sonuçlara göre birinci günde iki grup arasında ve beşinci günde iki gruparasında bağımsız örneklem t testi ve Mann-Whitney U testi neticesinde anlamlı farklılıklar olduğu (p

Analysis of Fibroblast Growth Factor (FGF-2) Effect on Cells Isolated from Pericardial Fluid

Pericardial fluid (PF) has a heterogeneous cell population. One of these cells is mesothelial cells that have the potential to differentiate into other cells, such as mesenchymal stem cells. The number of these cells increases with tissue damage and plays an important role in the repair of tissue/organ damage by synthesizing growth factors (VEGF, FGF-2, PDGF, TGF-b) and extracellular matrix (ECM) molecules. In this study, the effect of mesothelial cells on vascular tissue formation was investigated by adding FGF-2 (basic fibroblast Görowth factor) to cell culture medium. For this purpose, control group cells and groups of added growth factor were analyzed using light microscopy images at the first and fifth days. Using these images and image histograms, Hjorth parameters which are mobility, activity, complexity and, kurtosis, skewness and entropy values were analyzed statistically. On the first and fifth days, statistical analysis was performed to evaluate the differences between the groups calculated from the images of cells in culture with FGF-2 and without FGF-2 addition. According to the results of independent samples t test and Mann-Whitney U test showed significant differences between the two groups on the first day and between the two groups on the fifth day (p
