Abstract

The cellular and molecular mechanisms involved in the deposition of extracellular matrix components in both normal and fibrotic liver are still poorly understood. Ito cells (also called fat-storing cells or lipocytes), the principal cells residing in the Disse space, are considered to have great potential for fibrogenesis. Activated Ito cells are considered to be the main collagen producing cell type in normal and fibrotic liver. The aim of this study was to' investigate the presence of the Ito cells in normal and fibrotic liver tissue. In this experimental study, 17 rats were used. Seven rats were used as control group. In the other 10 rats, carbon tetrachloride (CCl4) was used for experimental induction of liver fibrosis. Autopsy was performed on all of the rats and liver tissues were totally removed. Ito cells were evaluated by immunohistochemical staining of laminin, type IV collagen, desmin and vimentin on paraffin sections. It was observed that Ito cells were specifically stained with laminin.

Özet

Normal ve fibrotik karaciğer dokusunda ekstraselüler matriks komponentlerinin depolanmasındaki selüler ve moleküler mekanizmalar hala tam olarak anlaşılamamıştır. Yağ depolayan hücreler veya lipositler olarak da bilinen İto hücreleri, fibrozis oluşmasında büyük bir rol oynamaktadır. Aktive olan İto hücreleri normal ve fibrotik karaciğerde başlıca kollagen üreten hücre tipidir. Sunulan çalışma normal ve fibrotik karaciğer dokusunda İto hücrelerinin varlığını araştırmak amacıyla yapıldı. Bu deneysel çalışmada 17 rat kullanıldı. Yedi rat kontrol grubu olarak ayrıldı. Onuna ise CCl4 verilerek karaciğer fibrozisi oluşturuldu. Daha sonra tüm ratlara otopsi yapılarak karaciğerleri total olarak çıkarıldı. Parafin kesitlere immunohistokimyasal olarak laminin, tip IV kollagen, desmin ve vimentin boyamaları yapılarak İto hücreleri değerlendirildi. Sonuç olarak, İto hücrelerinin lamininle spesifik olarak boyanma gösterdiği izlendi.
