Generation of Tumor Antigen-Specific iPSC-Derived Thymic Emigrants (iTE) using a Novel 3D Thymic Culture System

Project description:Induced Pluripotent Stem Cell (iPSC)-derived T cells may provide future therapies for cancer patients, but those generated by current methods, such as the OP9/DLL1 system, have shown abnormalities that pose major barriers for clinical translation. Our data indicate that these iPSC-derived CD8 single positive T cells are more similar to CD4+CD8+ double positive T cells than to mature naïve T cells, display markers of developmental arrest and exhibit characteristics of innate-like immune cells. We developed a 3D organ culture method which avoids these aberrant developmental fates, and generates a novel homogenous subset of CD8αβ+ antigen-specific T cells, iPSC-derived Thymic Emigrants (iTE). iTE exhibit phenotypic and functional similarities to naïve T cells both in vitro and in vivo, including an enormous capacity for expansion, memory formation and tumor suppression. These data illustrate the limitations of current methods and provide a blueprint for the generation of antigen-specific iTE with tremendous clinical potential.

Generation of Tumor Antigen-Specific iPSC-Derived Thymic Emigrants Using a 3D Thymic Culture System.

Project description:Induced pluripotent stem cell (iPSC)-derived T cells may provide future therapies for cancer patients, but those generated by current methods, such as the OP9/DLL1 system, have shown abnormalities that pose major barriers for clinical translation. Our data indicate that these iPSC-derived CD8 single-positive T cells are more like CD4+CD8+ double-positive T cells than mature naive T cells because they display phenotypic markers of developmental arrest and an innate-like phenotype after stimulation. We developed a 3D thymic culture system to avoid these aberrant developmental fates, generating a homogeneous subset of CD8αβ+ antigen-specific T cells, designated iPSC-derived thymic emigrants (iTEs). iTEs exhibit phenotypic and functional similarities to naive T cells both in vitro and in vivo, including the capacity for expansion, memory formation, and tumor suppression. These data illustrate the limitations of current methods and provide a tool to develop the next generation of iPSC-based antigen-specific immunotherapies.

CD205+ iPSc-derived thymic epithelial progenitor cells

Project description:We employed an ultra-sensitive bulk RNA sequencing approach to study thymic epithelial progenitor cells (TEPs) derived from iPSc differentiation and sorted by FACS based on their CD205 expression levels.

Mapping the thymic hematopoietic antigen presenting cell network

Project description:To characterize thymic APCs in an unbiased manner, we generated a scRNA-seq atlas of thymic antigen presenting cells (APCs) isolated from thymic rosettes, cellular complexes of physically interacting thymocytes and APCs. Around 8,000 APCs were captured, mostly haematopoietic in origin, consisting of B cell, dendritic cell and macrophage lineages.

Bulk RNA-seq time-course of human iPSc differentiation to thymic epithelial progenitors

Project description:Bulk RNA-seq was performed across a time-course of human iPSc differentiation toward thymic epithelial progenitors (TEPs). Twenty-nine experimental libraries spanning eleven time-points (days 0, 1, 2, 3, 7, 9, 10, 14, 15, 17, 22) plus four primary thymic epithelial cell (TEC) controls revealed progressive down-regulation of pluripotency genes and stepwise activation of transcriptional modules corresponding to anterior endoderm, third pharyngeal pouch endoderm, and thymic epithelial fate.

Isolated TEC and DC from human iPSc-derived thymic organoids (hTOs) seeded with primary early thymic progenitors (ETPs) at late phase of maturation (D28)

Project description:We employed an ultra-sensitive bulk RNA sequencing approach to study thymic epithelial cells (TECs), sorted by FACS based on their HLA-DR expression levels, and dendritic cells (DCs), both isolated from hTOs at the late stage of differentiation (day 28). These hTOs were generated by reaggregating iPSc-derived thymic epithelial progenitors (TEPs) with primary ETPs.

iPSc-to-thymic epithelial progenitor differentiation under multifactorial DoE optimization and transcriptomic profiling

Project description:This study investigates the differentiation of human induced pluripotent stem cells (iPSc) into thymic epithelial progenitors (TEPs) through a combinatorial experimental design (Design of Experiments, DoE). Bulk RNA-seq was performed across 96 differentiation conditions covering key developmental transitions: definitive endoderm (DE), anterior foregut endoderm (AFE), third pharyngeal pouch endoderm (3PPE), and thymic epithelial progenitors (TEP). The multifactorial screen leveraged Plackett-Burman designs and transcriptomic similarity to in vivo pharyngeal development atlases to identify optimal differentiation cues.

Project description:We have employed a single-cell sequencing approach to using 10x Genomics scRNA-seq to study the differentation/maturation of thymic epithalial cell progenitors (TEPs) obtained via our iPSc differentitation protocol based on design of experiment (DoE) in the early phase of hTO formation at D7after reaggregation with primary ETPs.
