间充质干细胞(MSC)可调节免疫系统并帮助组织修复,因此具有治疗潜力。然而,细胞存活率低、免疫排斥及临床应用相关伦理问题,限制了其广泛应用。为克服这些局限,MSC来源外泌体(MSC-EXO)作为创新且有前景的无细胞治疗策略受到关注。MSC-EXO是MSC释放的纳米级细胞外囊泡,携带多种生物活性分子,包括蛋白质、脂质和核酸。其具有MSC的许多益处,包括免疫调节、抗炎和组织修复。MSC-EXO可通过调节肿瘤微环境、抑制肿瘤生长并增强传统疗法疗效,发挥治疗潜力;还可特异性靶向细胞、递送治疗药物并诱导癌细胞凋亡。
此外,MSC-EXO可调节免疫应答、促进造血恢复并缓解治疗相关副作用。尽管MSC-EXO治疗前景良好,仍面临若干挑战,包括分离和表征方法标准化、作用机制阐明及安全性和疗效保障。尽管存在这些挑战,MSC-EXO疗法在血液学领域的未来仍值得期待。持续研究对于阐明外泌体复杂生物学、识别新型生物标志物和开发创新治疗策略至关重要。利用MSC-EXO有望变革血液系统疾病治疗并改善患者结局。
Mesenchymal stem cells (MSCs) offer promising therapy because they regulate the immune system and help repair tissues.
However, challenges such as low cell survival rates, immune rejection, and ethical concerns related to their clinical use have limited their widespread application. To overcome these limitations, MSC-derived exosomes (MSC-EXOs) have emerged as an innovative and promising cell-free therapeutic strategy. MSC-EXOs are nanosized extracellular vesicles released by MSCs that carry a diverse array of bioactive molecules, including proteins, lipids, and nucleic acids.
They share many benefits with MSCs, including immune regulation, anti-inflammatory effects, and tissue repair. MSC-EXOs demonstrate therapeutic potential by modulating the tumor microenvironment, suppressing tumor growth, and enhancing the efficacy of conventional therapies. They can specifically target cells, deliver therapeutic agents, and induce apoptosis in cancer cells.
Additionally, MSC-EXOs can modulate the immune response, promote hematopoietic recovery, and alleviate treatment-related side effects. While MSC-EXOs present a promising therapeutic approach, several challenges remain, including the standardization of isolation and characterization methods, understanding their mechanisms of action, and ensuring both safety and efficacy.
Despite these challenges, the future of MSC-EXO-based therapies in hematology is promising. Continued research efforts are essential to unravel the intricate biology of exosomes, identify novel biomarkers, and develop innovative therapeutic strategies. By harnessing the power of MSC-EXOs, we can revolutionize the treatment of hematological diseases and improve patient outcomes.
