354-髓母细胞瘤干细胞分子图谱

这项前瞻性研究探讨了髓母细胞瘤（MB）中癌症干细胞的演化过程，并详细分析了这些细胞如何通过劫持正常的大脑发育程序来驱动肿瘤的生长与扩散。文章强调，虽然基因测序已揭示了肿瘤的高度异质性，但目前的重点必须转向建立更精确的人类疾病模型，例如类器官和多能干细胞模型，以替代在模拟人类发育方面存在局限性的动物实验。作者指出，后转录调控（如可变剪接）和肿瘤微环境在病情恶化中起着关键作用，这些领域目前尚未被充分开发。此外，针对远处转移和复发机制的研究依然匮乏，而这正是导致患者死亡的主要原因。综上所述，未来必须通过功能验证来锁定新的治疗靶点，从而为这种恶性儿科脑瘤开发出更具针对性的精准医疗方案。References:* Zagozewski J, Haldipur P, Millen K J, et al.
