This research investigates the characteristics and behavior of purified fat-storing cells from rat liver in culture, focusing on their proliferative capacity and collagen content.
Established primary cultures and cell lines from purified fat-storing cells.
Conducted indirect immunofluorescence to analyze cytoskeletal components and collagen types.
Measured morphological and proliferative changes during multiple passages.
Fat-storing cells reached confluency in 3 to 4 days and maintained morphological characteristics.
Collagen types I and IV, along with laminin, were detected during primary culture and first passage; only collagen type I was noted in the fourth passage.
Cell multiplication correlated with a transition to a fibroblastic appearance and loss of vitamin A.
