摘要:

間充質干細胞（mesenchymal stem cells, MSCs）源于發育早期的中胚層，因其來源廣泛、具有多向分化潛能、低免疫原性和自我更新能力，在組織工程和再生醫學應用中顯示出巨大的潛力，也是當前基礎研究和臨床研究中應用最多的一類干細胞。然而，間充質干細胞的臨床應用面臨許多挑戰，比如治療所需細胞數量巨大，細胞質量存在異質性，細胞體內移植后存活率低，以及二維（two-dimensional, 2D）貼壁培養導致間充質干細胞特征衰減等。三維（three-dimensional, 3D）成球培養可以更好地模擬體內微環境，且大量的研究證明，3D成球培養增強了間充質干細胞的細胞存活和因子分泌能力，促進了干細胞特征維持、細胞遷移和血管生成，在臨床醫學領域具有廣闊的應用前景。基于此，綜述了體外3D成球培養的方法、3D成球培養優化的間充質干細胞的生物學特性及應用，并對3D成球培養未來的研究方向進行展望。

Abstract:

As an important branch of stem cell, mesenchymal stem cells (MSCs) are derived from the mesoderm at early embryonic development, which have shown great potentials in tissue engineering and regenerative medicine applications due to their extensive sources, multilineage differentiation potential, low immunogenicity and self�瞨enewal ability. However, MSCs are still confronting challenges in clinical applications due to requirement of large quantity of cells for therapy, heterogeneity of cell quality, low survival ability after transplantation, the attenuation of MSCs characteristics in two�瞕imensional (2D) culture and ambiguous mechanism of MSCs function for disease therapy. Three�瞕imensional (3D) spheroid culture is widely regarded as a more preferable and closer physiological microenvironment for cells growth. Studies reported that 3D spheroid culture enhanced the characteristics of MSCs on cell survival, factor secretion, stemness maintenance, migration, anti�瞫enescence in�瞯itro and enhanced the capacities of anti�瞚nflammatory, angiogenesis, tissue repair and regeneration in�瞯ivo. Therefore, 3D culture has broad application prospects in clinical application. In view of this, this article summarized the methods of 3D spheroid culture in vitro, and the spheroid biological characteristics and application briefly. Meanwhile, the prospects in future also have been discussed.
