Effects of n-3 Long-Chain Polyunsaturated Fatty Acid and Vitamin D Supplementation on Transcriptional Profiles of Human Lung Organoids.

ABSTRACT: Background/Objectives: Randomized clinical trials (RCTs) suggest that n-3 long-chain polyunsaturated fatty acids (n-3 LCPUFA) and high-dose vitamin D supplementation during pregnancy may protect against childhood asthma. However, the underlying mechanisms remain unclear. Methods: To explore the transcriptional effects of various concentrations of n-3 LCPUFA and vitamin D supplementation on in utero lung development, we cultured human lung organoids derived from BILX and SEHP human-induced pluripotent stem cell lines at the Sanger Institute (Cambridge, UK). The organoids were treated with either no supplementation, or low (0.01 µL/mL) or high (0.1 µL/mL) concentrations of n-3 LCPUFA, as well as no supplementation, or low (5 pM) or high (50 pM) concentrations of vitamin D.
