Bottom Line: WJ-MSCs expressed high levels of CD90 (93.6%) and CD105 (90.7%), but low levels of CD34 (0.3%) and CD45 (0.8%).Albumin production had significant difference in the two groups (p≤0.05).The data showed specific characteristics in favor of considering the differentiated cells as hepatocyte-like cells such as obtaining morphologic, functional, and αFP and HNF1-α expression patterns which in turn were higher in cells exposed to RA.

ABSTRACT

Background: Wharton's Jelly-Mesenchymal Stem Cells (WJ-MSCs) are pluripotent cells with differentiation capability into most cell lineages. The aim of the current work was to examine the role of Retinoic Acid (RA) in differentiation process of these cells into hepatocyte-like cells and determine the morphological and functional patterns.

Methods: Human WJ-MSCs were extracted, cultured and expanded; after approximately 95% of confluence, the cells were treated with hepatogenic media containing RA. The cells were subsequently analyzed for morphological changes, glycogen storage, albumin production, and specific gene expression.

Results: WJ-MSCs expressed high levels of CD90 (93.6%) and CD105 (90.7%), but low levels of CD34 (0.3%) and CD45 (0.8%). Albumin production had significant difference in the two groups (p≤0.05). The data showed specific characteristics in favor of considering the differentiated cells as hepatocyte-like cells such as obtaining morphologic, functional, and αFP and HNF1-α expression patterns which in turn were higher in cells exposed to RA.

Conclusion: Based on the data of present study, RA is an effective molecule in inducing differentiation of WJ-MSCs into hepatocyte-like cells; therefore, it may be considered as a promising factor for targeting therapy of liver disorders.

Mentions: Human WJ-MSCs at passage 3 were characterized by flow cytometry analysis (Figure 2) for the evaluation of stem cell markers expression. The cells expressed considerable levels of CD90 (93.6%) and CD105 (90.7%), but slight levels of CD34 (0.3%) and CD45 (0.8%). The expression rate for CD90 was the highest.
