Abstract (original English)

Hepatocellular carcinoma (HCC) is a significant global health challenge, being one of the leading causes of cancer-related mortality. This review focuses on the intricate interactions within the tumor microenvironment and mesenchymal stem cells (MSCs) and it's secretome in HCC and possible therapeutic responses. MSCs, characterized by their multipotent differentiation and self-renewal capabilities, can influence tumor behavior maybe through its secreted factors, including cytokines, growth factors and extracellular vesicles. This review summarizes the recent findings on role of MSCs in HCC, highlighting its involvement in different cell signaling pathways, including NF-κB, Wnt/β-catenin, Notch1, Stat3, and TGF-β, which play a significant role in HCC and possibly exhibit both tumor-suppressive and/or tumor-promoting effects depending on the activation or deactivation of signaling pathways. Publications related to the topic between 2016 to 2025 were searched using databases like PubMed, Scopus, Google Scholar with keywords viz. HCC, mesenchymal stem cells, secretome, tumor microenvironment, and signaling pathways. Findings from different research studies depict that MSCs and their secretome can exert anti-tumor effects by inducing apoptosis and enhancing immune responses, they may also promote alternate effects like tumor proliferation and metastasis under certain conditions, rel
