We evaluated the effect of serum-free and xeno-cultivation (SFXFM) on the characterization, proliferation, and differentiation properties of human nasal stem cells (airway tissue; hTMSCs). hTMSCs were isolated from 10 patients, after which patient samples were separated into two groups, an SFXFM group and a control group. The control group was treated with bovine serum-containing medium. FACS analysis revealed that SFXFM-cultured hTMSCs maintained a characteristic mesenchymal stem cell phenotype. hTMSC proliferation was not influenced by SFXFM. In addition, upregulation of IL-8 and GM-CSF and downregulation of RANTES expression were shown in response to SFXFM. Moreover, two-lineage differentiation properties (osteocyte and adipocyte) of hTMSCs were enhanced under SFXFM. Finally, the genetic stability of SFXFM-cultured hTMSCs was demonstrated by normal karyotype results. SFXFM enables good expansion, multipotentiality, and normal genotype maintenance of MSCs. Moreover, this approach serves as a substitute to conventional media for the cultivation of capable MSCs for upcoming medical applications.
我们评估了无血清异种培养(SFXFM)对人鼻干细胞(气道组织;hTMSCs)的特性、增殖及分化特性的影响。从10名患者中分离出hTMSCs,之后将患者样本分为两组,即SFXFM组和对照组。对照组用含牛血清的培养基处理。流式细胞术分析显示,经SFXFM培养的hTMSCs维持了典型的间充质干细胞表型。hTMSC的增殖不受SFXFM影响。此外,SFXFM可使IL-8和GM-CSF上调,RANTES表达下调。而且,在SFXFM条件下hTMSCs的双系分化特性(成骨细胞和脂肪细胞)增强。最后,正常核型结果证明了经SFXFM培养的hTMSCs的遗传稳定性。SFXFM能实现间充质干细胞的良好扩增、多能性及正常基因型维持。此外,这种方法可替代传统培养基用于培养有能力的间充质干细胞以用于未来的医学应用。
