Background: The liver microenvironment plays a key role in liver fibrosis and carcinogenesis. This study aimed to fill the gap in knowledge on the interaction between hepatic stellate cells and endothelial progenitor cells with biomarkers of liver fibrosis and/or carcinogenesis, including Col1A1, TGF-β, and tenascin-C.

Methods: CD34⁺ stem cells were isolated from umbilical-cord-blood mononuclear cells. 2D and 3D co-culture of CD34⁺ UCB SCs and LX2 was performed. The cells were incubated in a CO₂ incubator for three days. Morphological observation, qRT-PCR of TGF-β1 and COL1A1, and immunocytochemistry of tenascin-C were performed.

Results: CD34^{+ …}
