    • In this invention we propose a method to compose a stem cell culture niche platform, which is based on the use of the human amniotic membrane. Fluid dynamic, mechanical and topographic factors are additionally included in this niche to provide various factors essential for achieving an enhanced biomimetic micro environment of the cultured stem cells. The amniotic membrane is mounted into various types of culture platforms to suit a wide range of research applications. The rich composition of the membrane with anti-inflammatory, anti microbial, matrix and adhesion molecules in addition to various growth factors suits its application as a complex biomimetic material. The platform includes micro channels to allow continuous exchange of media and creates a dynamic flow of the fluid surrounding the cells in an attempt to simulate the in vivo conditions in which the stem cell typically reaches its ideal proliferation, expansion or differentiation. The method disclosed herein supports a wide range of applications in stem cell research such as the investigation of the optimal conditions for stem cell culture and the effect of various medications and external factors. It can be also applied in investigating the effect of the amniotic membrane and the mechanical factors on the behavior of stem cells and cancer stem cells. Another model of the niche is proposed as an in vivo moldableand implantable carrier for delivering stem cell based therapies in a wide range of diseases especially those associated with aging or decline of specialized cell function such as diabetes, cardiovascular, neurological, hormonal, renal and liver disorders, cancer, and diseases associated with inflammation and disordered immunity. Furthermore, the lack of HLA molecules renders the membrane naive to minimize rejection, which could be valuable for transplantation purposes.
    • 在本发明中,我们提出了一种构建干细胞培养菌落平台的方法,其基于人羊膜的使用。 流体动力学,机械学和地形学因素还包括在该利基中,以提供实现培养的干细胞的增强的仿生微环境所必需的各种因素。 将羊膜安装在各种培养平台上,以适应广泛的研究应用。 除了各种生长因子之外,具有抗炎,抗微生物,基质和粘附分子的膜的丰富组成适合其作为复合仿生材料的应用。 该平台包括微通道以允许介质的连续交换并且产生围绕细胞的流体的动态流动,以试图模拟干细胞通常达到其理想的增殖,扩增或分化的体内条件。 本文所公开的方法支持干细胞研究中广泛的应用,例如干细胞培养的最佳条件的研究以及各种药物和外部因素的影响。 它也可用于研究羊膜的影响和机械因素对干细胞和癌症干细胞的作用。 提出了另一个利基模型作为体内可模塑和可植入的载体,用于在广泛的疾病中特别是与特定细胞功能的衰老或衰退相关的干细胞基治疗,如糖尿病,心血管,神经学,激素,肾脏和肝脏 疾病,癌症和与炎症和无序免疫相关的疾病。 此外,缺乏HLA分子使膜变得天真,以使排斥最小化,这对于移植目的可能是有价值的。
