摘要

我们之前开发了一种具有成本效益的化学定义培养基配方，用于人诱导多能干细胞(hiPSCs)的周末无培养，成本为商业培养基价格的3%。我们将这种培养基命名为B8，专门针对hipsc的强劲快速生长和周末无培养基更换方案进行了优化。我们证明了这种培养基适合将体细胞重编程为hipsc并分化为各种谱系。在这里，我们提供了一种最具成本效益的培养基变体的简单生成方案，以及制作matrigel涂层板和培养，传代，冷冻保存和解冻hipsc的方案。©2020 Wiley期刊有限公司基本方案1:制备高度优化、稳健且具有成本效益的人诱导多能干细胞培养基基本方案2:在B8培养基中无周末维持和传代人诱导多能干细胞

Generating a Cost-Effective, Weekend-Free Chemically Defined Human Induced Pluripotent Stem Cell (hiPSC) Culture Medium

We have previously developed a cost-effective chemically defined medium formula for weekend-free culture of human induced pluripotent stem cells (hiPSCs), costing ∼3% of the price of commercial medium. This medium, which we termed B8, is specifically optimized for robust and fast growth of hiPSCs and for a weekend-free medium change regimen. We demonstrated that this medium is suitable for reprogramming of somatic cells into hiPSCs and for differentiation into a variety of lineages. Here, we provide a protocol for simple generation of the most cost-effective variant of this medium, along with a protocol for making Matrigel-coated plates and culturing, passaging, cryopreserving, and thawing hiPSCs. © 2020 Wiley Periodicals LLC.
