Stem cells, with their unique propensity to differentiate into various cell types, have become the linchpin of regenerative medicine [4]. This offers unprecedented prospects for tissue and organ repair and potential remedies for diseases once deemed incurable [5]. Notably, the advent of induced pluripotent stem cells (iPSCs) has marked a significant advancement by mitigating immune rejection and ethical dilemmas, while the integration of nanotechnology has refined the precision and effectiveness of stem cell-based therapies [6]. The influence of stem cell biology extends beyond conventional therapeutic boundaries, particularly in immunology, where engineered immune cells are designed to target and eliminate cancer, and in tissue engineering, which aspires to cultivate lab-grown organs [7-9]. Despite the promise, the path is fraught with challenges, including ethical quandaries, genomic stability, and potential tumorigenicity [10]. These complexities necessitate comprehensive research and strict regulatory oversight. Moreover, the intricate interplay between stem cells and the immune system presents both opportunities and obstacles, underscoring the need for ensuring the safety and efficacy of these therapies [11,12].
