Deksametason Kullanıldığında Myoblastlar Yüzeyindeki Değişikliklerin Scanning Elektron Mikroskobu İle İncelenmesi
Abstract
Hücreler fonksiyonlarına bağlı bazı yüzey özelliklerine sahiptir.Metabolizması değişen hücrelerin yüzeyinde de bazı değişiklikler beklenir.Bu çalışmada fareden elde edilen N-ras Onkogeni bağlanmış myoblastlar değişik kültür ortamlarında üretildi. Ortama deksametazon eklenerek değişik kültür ortamının ve dekzametazonun etkileri sonucu hücrelerin yüzeylerindeki değişiklikler scanning Elektron Mikroskop ile incelendi. Değişik kültür ortamında, üretilen hücrelerin yüzeylerinde bazı farklılıklar tespit edildi. Ortama deksametazon eklenmesinden sonra hücrelerin yüzeylerinde mikrovilli artışı yanı sıra düzensiz kıvrıntı, kabartı, katlantı gibi deformasyon özellikeri tespit edildi.

EXAMINATION OF CHANGES ON THE SURFACE OF MYOBLASTS WHEN DEXAMETHASONE IS USED BY SCANNING ELECTRON MICROSCOPE
Abstract
Cells have certain surface characteristics depending on their functions, When the metabolism of the cells changes, some differences on their surfaces are also expected. In this study, the myoblasts, given N-ras oncogen were produced in different cultur media, Dexamethasone was added to the medium and the effects ol media and dexamethasone on the surfaces of these cells were examined by a scanning electron microscopy. Certain differentiations were determined on the surface of cells grown in different cultur media. The increases of microvilli and some deformalion characteristics such as rufiling and swelling were determined after adding dexamethasone to the cultur medium.
