干细胞的命运受到许多因素和相互作用的影响,这些因素和相互作用需要强大的控制来安全有效地再生功能组织。与可溶性因子、其他细胞和细胞外基质的协调相互作用定义了干细胞感测的具有复杂和动态调节的局部生化和机械小生境。脱细胞组织基质和合成聚合物壁龛正在临床上使用,它们也开始阐明干细胞如何有助于稳态和修复的基本方面,例如,在纤维化部位。越来越需要多方面的技术来生产和询问离体细胞,建立预测模型,并最终增强干细胞体内整合以获得治疗益处。
Stem cell fate is influenced by a number of factors and interactions that require robust control for safe and effective regeneration of functional tissue. Coordinated interactions with soluble factors, other cells, and extracellular matrices define a local biochemical and mechanical niche with complex and dynamic regulation that stem cells sense. Decellularized tissue matrices and synthetic polymer niches are being used in the clinic, and they are also beginning to clarify fundamental aspects of how stem cells contribute to homeostasis and repair, for example, at sites of fibrosis. Multi-faceted technologies are increasingly required to produce and interrogate cells ex vivo, to build predictive models, and ultimately to enhance stem cell integration in vivo for therapeutic benefit.
