METHODS: Trachea and lung organoids were derived from mixed cell populations of mice primary airway epithelial cells, fibroblasts, and lung microvascular endothelial cells and directly digested from the whole cell population in the distal lung.
RESULTS: The formation of spheres appeared as early as 3 days and continued to proliferate until day 5. The generation of trachea and lung organoids self-organised into discrete epithelial structures was formed within less than 10 days.
CONCLUSION: We conclude that researchers will be able to examine cellular involvement during organ formation and molecular networks because organoids come in a variety of morphologies and stages of development, and this organoid protocol may be used for modelling lung diseases as a platform for therapeutic purposes and suitable for personalised medicine for respiratory diseases.
