Pluripotent stem cells as a promising cell source with unlimited proliferation and differentiation capacity hold great promise for cell-based therapies in regenerative medicine. Establishment of appropriate culture conditions might enable the control of cellular fate decision in cell culture. Transfer of three-dimensional (3D) embryoid bodies to two-dimensional (2D) monolayer culture systems for initiation of cell differentiation and specialization requires an adaptation of cells which can be managed by extracellular matrix (ECM) materials. Here we compare the characteristics of four different cell culture coating materials and their effect on attachment and differentiation of cells spreading from mouse embryonic stem cell (mESC) derived embryoid bodies (EBs) in mesoderm inducing culture conditions. Atomic force microscope (AFM) and scanning electron microscope (SEM) analysis along with Water Contact Angle technique were used to analyze physical properties of ECM materials and to evaluate cellular behavior on surfaces. Cell migration and differentiation were performed initially by using mesoderm inducing culture conditions and then three germ layer specification conditions. We investigated properties of coating materials such as roughness and wettability control cell attachment, migration and differentiation of mESCs. Matrigel-Gelatin combination is suitable for cell attachment and migration of cells spreading from 3D EBs followed by transfer onto coated surfaces. Matrigel-Gelatin coating enhanced differentiation of cells into mesoderm like cells via EMT process. Our data demonstrated that the Matrigel-Gelatin combination as a cell culture coating matrix might serve as a suitable platform to transfer EBs for differentiation and might influence pluripotent stem cell fate decision into mesoderm and further mesoderm derivative cell populations.

多能干细胞作为一种具有无限增殖和分化能力的有前景的细胞来源,在再生医学的细胞治疗中具有巨大潜力。建立合适的培养条件可能有助于控制细胞培养中的细胞命运决定。将三维(3D)胚状体转移到二维(2D)单层培养系统以启动细胞分化和特化需要细胞进行适应,这可以通过细胞外基质(ECM)材料来实现。在这里,我们比较了四种不同细胞培养包被材料的特性及其对从中胚层诱导培养条件下从小鼠胚胎干细胞(mESC)衍生的胚状体(EBs)扩散而来的细胞的附着和分化的影响。使用原子力显微镜(AFM)、扫描电子显微镜(SEM)分析以及水接触角技术来分析ECM材料的物理性质并评估细胞在表面的行为。最初在中胚层诱导培养条件下,然后在三个胚层指定条件下进行细胞迁移和分化。我们研究了诸如粗糙度和润湿性等包被材料特性对mESCs细胞附着、迁移和分化的控制作用。基质胶 - 明胶组合适合于从3D EBs扩散而来的细胞的附着和迁移,随后转移到包被表面。基质胶 - 明胶包被通过上皮 - 间质转化(EMT)过程增强细胞向中胚层样细胞的分化。我们的数据表明,基质胶 - 明胶组合作为细胞培养包被基质可能是一个合适的平台,用于转移EBs进行分化,并可能影响多能干细胞向中胚层及进一步的中胚层衍生细胞群体的命运决定。
