Objectives: This study compared rate of cell proliferation, viability, cell size, expression patterns of genes related to pluripotency and epigenetic modification between canine foetal fibroblasts (cFF) and canine adipose tissue-derived mesenchymal stem cells (cAd-MSC). Materials and methods: Proliferation pattern, cell viability as well as cell size at each passage of cFF
and cAd-MSC were measured when cultures reached confluence. In addition, real-time PCR was performed to investigate expression of Dnmt1,
HDAC1, OCT4, SOX2, BAX, BCL2 genes with reference to b-actin gene expression as an endogenous control in both cell lines.
