Single-cell RNA-Seq of mouse thyroid organoid

ABSTRACT: The thyroid gland regulates metabolism and growth via secretion of thyroid hormone by thyroid follicular cells (TFCs). Loss of TFCs, by cellular dysfunction, autoimmune destruction or surgical resection, underlies hypothyroidism. Recovery of thyroid hormone levels by transplantation of mature TFCs derived from stem cells in vitro holds great therapeutic promise. However, the utilization of in vitro derived tissue for regenerative medicine is restricted by the efficiency of differentiation protocols to generate mature organoids. Here, to improve the differentiation efficiency for thyroid organoids, we utilized single-cell RNA-Seq to chart the molecular steps undertaken by individual cells during the in vitro transformation of mouse embryonic stem cells to TFCs. Our single-cell atlas of mouse organoid systematically and comprehensively identifies, for the first time, the cell-types generated during production of thyroid organoids. Using pseudotime analysis, we identify molecular pathways that regulate thyroid maturation in vitro. Our study highlights the potential of single-cell molecular characterization in understanding and improving thyroid maturation, and paves the way for identification of therapeutic targets against thyroid disorders.

Generation of thyroid follicular cell organoids from adult thyroid tissue [Mouse single-cell]

Project description:The thyroid maintains systemic homeostasis by regulating serum thyroid hormone concentrations. Here we report the establishment of adult stem cell-derived three-dimensional (3D) organoids representing murine and human thyroid follicular cells (TFCs). The TFC organoids (TFCO) harbour the complete machinery of hormone production as visualised by the presence of colloid in the lumen and by the presence of essential transporters and enzymes in the polarised epithelial cells that surround a central lumen. Both the established murine as human thyroid organoids express canonical thyroid markers PAX8 and NKX2.1, while the thyroid hormone precursor thyroglobulin is expressed at comparable levels to tissue. Single cell RNA sequencing and transmission electron microscopy confirm that TFCOs phenocopy primary thyroid tissue. Thyroid hormones are readily detectable in conditioned medium of human TFCOs.

Transcriptional profiling of pax2a-Low and pax2a-High thyroid follicular cells in zebrafish

Project description:Thyroid follicular cells (TFCs) are responsible for generation, storage and release of thyroid hormone. Single-cell analysis of zebrafish thyroid gland demonstrated transcriptional heterogeneity within the TFC population (Gillotay et al., bioRxiv, 2020. doi: 10.1101/2020.01.13.891630. GEO dataset for single-cell RNA-Seq.: GSE133466). Particularly, TFC displayed transcriptional heterogeneity in the expression of pax2a, a transcription factor involved in differentiation and maturation of TFCs. To validate the genetic heterogeneity, we generated a pax2a knock-in line, in which mKO2 expression is driven by endogenous pax2a locus. Using Tg(tg:nls-EGFP); pax2a:mKO2-Knock-in, we sorted for TFCs (GFP+) and separated the pax2a-Low (mKO2-Low) and pax2a-High (mKO2-High) populations for NGS.

Bulk ATAC-seq of Foxe1KO and control Nkx2-1/mKO2+ mouse ESC-derived cells

Project description:Functional thyroid follicles generation in vitro is obtained at high efficiency by doxycycline-mediated expression of Nkx2-1 and Pax8, two proteins involved in early specification of thyroid lineage. Although those factors are sufficient to induce thyroid specification in vitro, other players, such as Foxe1, are also present in early thyroid primordium and its loss-of-function is responsible for thyroid congenital defects in mice and humans. Here we show that Foxe1KO mESCs can be induced to differentiate towards thyroid lineage but the efficiency of thyroid follicular cells generated is drastically low. Moreover, correct expression of maturation genes and capacity to produce thyroid hormone in vitro are completely disrupted. On the other hand, Nkx2-1 expressing cells derived from Foxe1KO have an unexpected ability to deviate to a lung epithelium differentiation program and form organoids containing multiple lung cell types. These findings demonstrate that Foxe1 is required to reinforce thyroid cell fate in vitro and to promote terminal maturation of thyroid follicles.

Bulk RNA-Seq of human thyroid organoids

Project description: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.
