Overview

STEMdiff™ Branching Lung Organoid Kit (Catalog #100-0195) is a serum-free medium system for efficient and reproducible generation of branching lung organoids from human embryonic stem (ES) and induced pluripotent stem (iPS) cells through four stages of differentiation: 1) definitive endoderm, 2) anterior foregut endoderm, 3) lung bud organoid, and 4) branching lung organoids. STEMdiff™ Branching Lung Organoid Kit has been optimized for differentiation of cells maintained in mTeSR™1 (Catalog #85850). Resulting organoids will develop proximal and distal-like branching airway epithelial structures expressing EPCAM, NKX2.1, SOX2, SOX9, MUC1, and P63. When maintained beyond 28 days in a Matrigel® sandwich, there is an increase in expression levels of markers for more mature lung cells, such as SFTPC, SFTPB, and ABCA3. For extended periods of organoid culture (> 28 days in the Matrigel® sandwich), the components required for branching lung organoid maturation are available in STEMdiff™ Branching Lung Organoid Maturation Kit (Catalog #100-0528).
Advantages:
⦁ Physiologically relevant model system that recapitulates in vivo airway branching morphogenesis and proximo-distal specification
⦁ Robust medium supports efficient differentiation of human ES and iPS cell lines to branching lung organoids
⦁ Convenient format with cryopreservable intermediate stage for experimental flexibility

Schematic showing the different stages in the STEMdiff™ Branching Lung Organoid Kit protocol and the representative morpholgy at each stage.

Figure 1. Generation Of Branching Lung Organoids Using the STEMdiff™ Branching Lung Organoid Kit

(A) Human PSC cultures progress through a four-stage differentiation process to generate human branching lung organoids. By the end of stage 1 (day 3), cultures exhibit characteristics typical of definitive endoderm and anterior foregut differentiation is initiated. During stage 2 (days 3 - 6) anterior foregut endoderm buds are released from the monolayer, and are then suspended to form ventralized lung bud organoids in stage 3 (days 6 - 14). In stage 4, the lung bud organoids are embedded into Matrigel sandwich cultures to mature into branching lung organoids. (B) Morphological representation of the culture at different stages.

Flow cytometry data at the end of stage 2 demonstrating expression of SOX2 and absence of CDX2 in AFE buds and brnaching lung organoids cultured beyond stage 4 demonstrating the expression of CPM and NKX2.1.

Figure 2. STEMdiff™ Branching Lung Organoid Kit Supports Expression of Key Lung Markers at Different Stages

Flow cytometric analysis at different stages of the STEMdiff™ Branching Lung Organoid Kit workflow shows protein expression of key lung markers. (A) Anterior foregut endoderm (AFE) buds generated at the end of stage 2 demonstrates high expression of the anterior foregut marker, SOX2 and absence of mid/hindgut marker, CDX2. (B) Cells from branching lung organoids on day 42 (stage 4) express lung progenitor marker NKX2.1 and its surrogate cell surface marker CPM. (C) NKX2.1 and CPM expression are maintained in long-term cultures as seen by flow cytometric analysis of cells from branching lung organoids (day 67).

Figure 3. Branching Lung Organoids Cultured in STEMdiff™ Branching Lung Organoid Kit Feature Key Protein Markers and Exhibit Branching Morphogenesis

(A) Branching lung organoids express lung progenitor marker NKX2.1 throughout their branching structures, and (B, C) demonstrate the presence of alveolar type II-like cells with Pro-surfactant protein B and C expressions. (D, E) These organoids undergo proximodistal differentiation demonstrated by the differential expression of SOX2 and SOX9. (F) MUC1 can be found luminally expressed while the (G) organoids are surrounded by VIM-expressing mesenchyme. (H, I) Branching lung organoids generated in STEMdiff™ Branching Lung Organoid Kit also express proteins associated with SARS-CoV-2 entry, ACE2 and TMPRSS2. Protein expression was visualized by immunohistochemistry and confocal microscopy of branching lung organoids on day 63.

Figure 4. Branching Lung Organoids Cultured in STEMdiff™ Branching Lung Organoid Maturation Kit For Extended Periods Express More Mature Lung Markers

(A) The branching tips of branching lung organoids derived from peripheral blood endothelial progenitor cell-derived iPS cells (iPSC-1), peripheral blood mononuclear cell-derived iPS cells (iPSC-2) or embryonic stem cells (H1 and H9) continue to grow and branch up to day 101. (B) The expression levels of more mature distal lung markers ABCA3, SFTPC, and SFTPB increase overtime. Morphology and gene expression were assessed by RT-qPCR of branching lung organoids cultured up to day 101.

Gene expression data of branching lung organoids of key lung markers like NKX2.1, MUC1, SFTB, SFTC, ABCA3 and the absence of off-target markers like PAX8 and FOXG1.

Figure 5. Branching Lung Organoid Cells Are Specifically Differentiated Towards the Lung

Gene expression profile of branching lung organoids (day 42+) analysed by RT-qPCR show presence of key lung markers and absence of off-target markers. Branching lung organoids at day 42 express (A) lung-thyroid-forebrain marker NKX2.1 and does not exhibit thyroid marker PAX8 and forebrain marker FOXG1. (B) The expressions of proximal lung marker MUC1 and distal lung markers SFTPC, SFTPB, and ABCA3 are upregulated in day 56 branching lung organoids, when compared to respective pluripotent stem cells (PSCs). All expression levels are normalized to the housekeeping gene TBP. iPSC-1: peripheral blood endothelial progenitor cell-derived iPS cells; iPSC-2: peripheral blood mononuclear cell-derived iPS cells.
