Accurate disease models are essential for understanding disease pathogenesis and for developing new therapeutics. As stem cells are capable of self-renewal and differentiation, they are ideally suited both for generating these models and for obtaining the large quantities of cells required for drug development and transplantation therapies. Jellyfish collagen is showing great promise as a next generation matrix enabling improved outcomes in 2D and 3D cell culture and regenerative medicine. Here, we report the potential of jellyfish collagen for culturing induced pluripotent stem cell derived cell lines (iPSCs) for modeling human diseases. Jellyfish collagen from Rhizostoma pulmo (Jellagen®) was evaluated for the growth and viability of iPSC-derived microglial-like cells (iMGL) comparing to cells cultured on rat tail collagen 1, laminin-511 and tissue culture plastic. Viability was measured using MTT, XTT, Alamar Blue and Annexin V, since this last assay has the aim of evaluating the onset of apoptosis. Cell ramification was measured using Neurotracker software and ramification measured on the InCucyte S3TM. Cell surface receptor expression was quantified using flow cytometry. Microglia markers used for immunocytochemistry were IBA1, CD11b, TREM2, TMEM119, and P2RY12. We report that iPSC-derived microglia can be successfully cultured on Jellagen® jellyfish collagen demonstrating a more ramified cell morphology compared to cells cultured on mammalian rat tail collagen I and comparable to Laminin-511.

水母胶原蛋白作为 iPSC 衍生小胶质细胞生长和培养的新研究工具的生物学评价

准确的疾病模型对于了解疾病发病机制和开发新疗法至关重要。由于干细胞能够自我更新和分化,因此它们非常适合生成这些模型以及获得药物开发和移植治疗所需的大量细胞。水母胶原蛋白作为下一代基质显示出巨大的前景,可改善 2D 和 3D 细胞培养和再生医学的结果。在这里,我们报告了水母胶原蛋白在培养诱导多能干细胞衍生细胞系 (iPSC) 以模拟人类疾病方面的潜力。与在大鼠尾胶原蛋白 1 上培养的细胞相比,评估了来自肺根瘤菌 (Jellagen®) 的水母胶原蛋白的 iPSC 衍生的小胶质细胞样细胞 (iMGL) 的生长和活力,层粘连蛋白 511 和组织培养塑料。使用 MTT、XTT、Alamar Blue 和 Annexin V 测量生存力,因为最后一个测定的目的是评估细胞凋亡的发生。使用 Neurotracker 软件测量细胞分枝,并在 InCucyte S3TM 上测量分枝。使用流式细胞术定量细胞表面受体表达。用于免疫细胞化学的小胶质细胞标记物是 IBA1、CD11b、TREM2、TMEM119 和 P2RY12。我们报告说,iPSC 衍生的小胶质细胞可以在 Jellagen® 水母胶原蛋白上成功培养,与在哺乳动物大鼠尾胶原蛋白 I 上培养的细胞相比,表现出更加分枝的细胞形态,并且与 Laminin-511 相当。使用 Neurotracker 软件测量细胞分枝,并在 InCucyte S3TM 上测量分枝。使用流式细胞术定量细胞表面受体表达。用于免疫细胞化学的小胶质细胞标记物是 IBA1、CD11b、TREM2、TMEM119 和 P2RY12。我们报告说,iPSC 衍生的小胶质细胞可以在 Jellagen® 水母胶原蛋白上成功培养,与在哺乳动物大鼠尾胶原蛋白 I 上培养的细胞相比,表现出更加分枝的细胞形态,并且与 Laminin-511 相当。使用 Neurotracker 软件测量细胞分枝,并在 InCucyte S3TM 上测量分枝。使用流式细胞术定量细胞表面受体表达。用于免疫细胞化学的小胶质细胞标记物是 IBA1、CD11b、TREM2、TMEM119 和 P2RY12。我们报告说,iPSC 衍生的小胶质细胞可以在 Jellagen® 水母胶原蛋白上成功培养,与在哺乳动物大鼠尾胶原蛋白 I 上培养的细胞相比,表现出更加分枝的细胞形态,并且与 Laminin-511 相当。
