Reassessing the Tumorigenic Risk and Antitumor Potential of Pluripotent Stem Cells: Mechanistic Insights and Translational Implications
Abstract Pluripotent stem cells (PSCs) have long been associated with tumorigenic risk, primarily due to their capacity to form teratomas in preclinical models. However, these findings are predominantly derived from studies conducted in immunocompromised hosts. Emerging evidence suggests that in immunocompetent environments, PSCs are efficiently cleared and do not form tumors. Furthermore, increasing data indicate that PSC-derived factors—particularly exosomes and microRNAs—may exert anti-tumor effects by reprogramming malignant cells and modulating
