Protocol for generating three-dimensional induced early ameloblasts using serum-free media and growth factors.

Adult humans cannot regenerate the enamel-forming cell type, ameloblasts. Hence, human induced pluripotent stem cell (hiPSC)-derived ameloblasts are valuable for investigating tooth development and regeneration. Here, we present a protocol for generating three-dimensional induced early ameloblasts (ieAMs) utilizing serum-free media and growth factors. We describe steps for directing hiPSCs toward oral epithelium and then toward ameloblast fate. These cells can form suspended early ameloblast organoids. This approach is critical for understanding, treating, and promoting regeneration in diseases like amelogenesis imperfecta.
