Immunohistochemical Distribution Of Transforming Growth Factor Alpha,Laminin, Fibronectin And Desmin In Rat Ovary, Gökhan Akkoyunlu, İsmai̇l Üstünel, Ramazan Demi̇r
Turkish Journal of Biology
Since the pure synthesis of transforming growth facto alpha (TGF\alpha) many attempts have been made in order to determine its distribution in various tissues. As a result of the complexitiy of the cyclic periods throughout experimental models, it is not easy to determine the distribution of TGF\alpha in the system. Especially the pre-and through-gestational pattern of TGF\alpha in rat ovary has not been reported fully. Furthermore, the shortage of literature about intracellular desmin and laminin, fibronectin of different intermediate filaments whether they have any interaction with TGF\alpha through this period, makes the subject worth discussing. Immunocytochemical techniques were utilized in …

In this investigation of the primary ossification zones of 14-18 day-old fetal rat humeri by histological, histochemical and histoenzymatical methods, 30 rat fetuses of the species Rattus norvegicus were used. The humeral diaphysis samples of the fetuses were subjected to alcian blue-heamatoxylin, periodic acid Schiff (PAS)-heamatoxylin, alcian blue-PAS-heamatoxylin, alizarin red and toluidine blue, alkaline phosphatase (ALP), adenosine triphosphatase (ATPase) and acid phophatase (ACP) staining techniques. The results can be summarized as follows: On day 14, no ossification signs were evident yet, whereas on day 15, the initiation of degenerations in some chondrocyte cytoplasms and the formation of osteoblastic cells on …
