Single-cell RNA-Seq of human thyroid organoid II
The function of the thyroid gland is to metabolize iodide to synthesize hormones that act on almost all tissues and are essential for normal growth and metabolism. Low plasma levels of thyroid hormones lead to hypothyroidism, which is one of the most common diseases in the general population and cannot be always satisfactorily treated by lifelong hormone replacement. Therefore, in addition to the lack of in vitro tractable models to study human thyroid development, differentiation and maturation, there is a need for new therapeutic approaches that involve replacement of thyroid tissue to better control hormone balance. Here we report the first model of thyroid organoids derived from human embryonic stem cells that produce thyroid hormones in vitro and are capable of restoring plasma thyroid hormone levels when transplanted into athyreotic mice. Overall design: Cells originating from human thyroid differentiation protocol, at day 58, were isolated for scRNAseq profiling. Different proportions of viable NKX2-1/GFP+ (60 %) and NKX2-1/GFP- (40 %) cells were sorted and combined in a single tube. Around 6,000 cells were loaded onto a channel of the Chromium Single Cell 3' microfluidic chip and barcoded with a 10X Chromium controller followed by RNA reverse transcription and amplification according to manufacturer's recommendations (10X Genomics).
