Transcriptional characterization of Human Lung Organoids (HLOs) using RNAseq
Human lung organoids (HLOs) were derived from human embryonic stem cell line H9 NIH registry #0062. Sequencing of HLOs was performed by the UM DNA Sequencing Core, using Illumina Hi-Seq platform and single-end 50 bp reads. The UM Bioinformatics Core downloaded the reads files from the Sequencing Core storage, and concatenated those into a single .fastq file for each sample. 3 HLOs were cultured for 65 days and 3 HLOs were cultured in vitro for 110 days.  HLO Culture Protocol 4-day Activin A (R&D systems) differentiation protocol was used to derive definitive endoderm from human pluripotent stem cells (hPSCs). Cells were treated with Activin A (100?ng?ml-1) for three consecutive days in RPMI 1640 media (Life Technologies) with increasing concentrations of 0%, 0.2% and 2% HyClone defined fetal bovine serum (dFBS, Thermo Scientific). The fourth day was a repeat of day 3 media (2% HyClone FBS).   After differentiation into definitive endoderm, cells were incubated in foregut media (advanced DMEM/F12 plus N-2 and B27 supplement, 10mM Hepes, 1x L-Glutamine (200mM), 1x Penicillin-streptomycin (5,000 U/mL, all from Life Technologies)) with 200ng/mL Noggin (NOG, R&D Systems) and 10µM SB431542 (SB, Stemgent) for 4 days, SB, 500ng/mL FGF4 (R&D Systems), and 2 µM CHIR99021 (Chiron, Stemgent), and 1µM SAG (Enzo Life Sciences) for 4-6 days. After 4 days with treatment of growth factors, three-dimensional floating spheroids were present in the culture. Three-dimensional spheroids were transferred into Matrigel to support 3D growth. Spheroids were embedded in a droplet of Matrigel (BD Bioscience  #356237) in one well of a 24 well plate, and incubated at room temperature for 10 minutes. After the Matrigel solidified, foregut media with 1% Fetal bovine serum (FBS, CAT#: 16000-044, Life Technologies) and 500ng/mL FGF10 (R&D Systems) were overlaid and replaced every 4 days. Organoids were transferred into new Matrigel droplets every 10 to 15 days.
