项目摘要
Stem cells are a powerful tool in biomedical research and applications, including generation of complex _in vitro_ models, disease modelling, cell therapy and drug discovery. Furthermore, stem cells can differentiate to form different types of cells, tissues and organs and can be grown to mimic diseases such as cancer and other tissue-related disorders. Within the stem cell environment, differentiation is influenced by extracellular matrix components and growth factors, which provide key instructive signals. Of particular interest are their use in generating organoids (mini organs), where clusters of stem cells come together to mimic the native microenvironment of tissues and organs.A motivation for the use of stems cells is their extraordinary potential of changing our understanding of basic biology, and the development of complex preclinical models. They also have the capacity to reduce animal usage in research and development. The growth and differentiation of stem cells in 3-dimensional (3D) have largely been demonstrated with the use of commercially available animal-derived product (3D gel). As well as ethical issues involved in its harvest, this product have significant batch-to-batch variability occurring from inter-individual species and inter-supplier variation. This animal-derived 3D gel also demonstrates thermo-responsive properties, displaying liquid properties at 4oC but forming a gel at room temperature. This significantly impacts how scientists work with it and its translational capacity in high-throughput applications, as these parameters are not compatible with essential high throughput and robotic systems. Most experiments using this product are therefore not reproducible and make data interpretation difficult.To fully understand the differentiation ability of stem cells and develop their capacity to reduce animal usage in research, it is imperative to have a non-animal derived 3D gel that shows consistent batch production, easy to handle properties for better translation in a laboratory or clinical setting. Our PeptiGel(r) products are biologically relevant, synthetic hydrogels that mimic a tissues' cellular environment through having tuneable properties to simulate the natural extracellular matrix of a native tissue. They have been shown to support the growth of a variety of cell types. However robust data of PeptiGels(r) interactions with stem cell populations is lacking. Therefore, the aim of this project is to reproducibly assess and validate PeptiGel(r) products to understand the ideal growth and differentiation environmental conditions for human mesenchymal stem cell culture. The successful completion of this project will drive forward PeptiGel(r) market penetration, further develop solutions for mesenchymal stem cell work and increase revenue.
干细胞在生物医学研究和应用中是一个强大的工具,包括生成复杂的体外模型、疾病建模、细胞治疗和药物发现。此外,干细胞可以分化形成不同类型的细胞、组织和器官,并可以培养成模拟癌症和其他组织相关疾病等疾病。在干细胞环境中,分化受到细胞外基质成分和生长因子的影响,它们提供了关键的指导信号。特别令人感兴趣的是它们在生成类器官(微型器官)中的使用,在这些器官中,成团的干细胞聚集在一起模拟组织和器官的自然微环境。使用干细胞的一个动机是它们具有改变我们对基础生物学的理解的非凡潜力,以及复杂的临床前模型的发展。它们还有能力减少研究和开发中的动物使用量。干细胞在三维(3D)中的生长和分化在很大程度上是通过使用商业上可用的动物衍生产品(3D Gel)来展示的。除了收获过程中涉及的道德问题外,这种产品在不同品种之间和供应商之间存在显著的批次差异。这种来自动物的3D凝胶也表现出温度响应特性,在4摄氏度时表现出液体特性,但在室温下形成凝胶。这严重影响了科学家如何使用它以及它在高吞吐量应用中的翻译能力,因为这些参数与基本的高吞吐量和机器人系统不兼容。因此,使用该产品的大多数实验都是不可重复性的,并使数据解释变得困难。为了充分了解干细胞的分化能力,并发展其在研究中减少动物使用的能力,必须拥有一种非动物来源的3D凝胶,该凝胶具有一致的批量生产、易于操作的特性,以便在实验室或临床环境中更好地翻译。我们的PeptiGel(R)产品是与生物相关的合成水凝胶,通过具有可调节的特性来模拟天然组织的细胞外基质,从而模拟组织的细胞环境。它们已被证明支持多种细胞类型的生长。然而,缺乏关于PeptiGels(R)与干细胞群体相互作用的可靠数据。因此,该项目的目的是对PeptiGel(R)产品进行可重复性评估和验证,以了解用于人类间充质干细胞培养的理想生长和分化环境条件。该项目的成功完成将推动PeptiGel(R)的市场渗透,进一步开发间充质干细胞工作的解决方案,并增加收入。
