Efficient derivation of microglia-like cells from human pluripotent stem cells

ABSTRACT: Microglia-like cells and neural cells were generated from several hES and hIPS lines. As subset was characterized by RNA seq and compared to expression profiles of published primary and induced samples. ABSTRACT: Microglia, the only lifelong resident immune cells of the central nervous system (CNS), are highly specialized macrophages which have been recognized to play a crucial role in neurodegenerative diseases such as Alzheimer’s, Parkinson’s and Adrenoleukodystrophy (ALD). However, in contrast to other cell types of the human CNS, bona fide microglia have not yet been derived from cultured human pluripotent stem cells. Here we establish a robust and efficient protocol for the rapid production of microglia-like cells from human embryonic stem (ES) and induced pluripotent stem (iPS) cells that uses defined serum-free culture conditions. These in vitro pluripotent stem cell-derived microglia-like cells (termed pMGLs) faithfully recapitulate the expected ontogeny and characteristics of their in vivo counterparts and resemble primary fetal human and mouse microglia. We generated these cells from multiple disease-specific cell lines, and find that pMGLs derived from MeCP2 mutant hES cells are smaller than their isogenic controls. We further describe a culture platform to study integration and live behavior of pMGLs in organotypic 3D-cultures. This modular differentiation system allows the study of microglia in highly defined conditions, as they mature in response to developmentally relevant cues, and provides a framework to study the long-term interaction of microglia residing in a tissue-like environment.

Generation of pluripotent stem cells from adult human testis

Project description:Human primordial germ cells and mouse neonatal and adult germline stem cells are pluripotent and derive embryonic stem cell properties. Here we report the successful establishment of stable pluripotent human adult germline stem cells (haGSCs) derived from spermatogonial cells of adult human testis. Cellular and molecular characterization of haGSCs revealed many similarities to human embryonic stem (hES) cells and haGSCs produced teratomas after subcutaneous transplantation into immunodeficient mice. The haGSCs differentiated into various types of somatic cells of all three germ layers when grown under conditions used to induce the differentiation of hES cells. We conclude that the generation of haGSCs from testicular biopsies may provide simple and non-controversial access to individual cell-based therapy without the ethical and immunological problems associated with hES cells.

Differentiation of human and murine induced pluripotent stem cells to microglia-like cells [mouse]

Project description:Microglia are the resident inflammatory cells of the central nervous system (CNS) and have important roles in development, homeostasis and a variety of neurologic and psychiatric diseases. Difficulties in procuring human microglia have limited their study and hampered the clinical translation of microglia-based treatments shown to be effective in animal disease models. Here, we report the differentiation of human induced pluripotent stem cells (iPSC) into microglia-like cells by exposure to defined factors and co-culture with astrocytes. These iPSC-derived microglia (iPS-MG) have the phenotype, gene expression profile and functional properties of brain-isolated microglia. Murine iPS-MG generated using a similar protocol have equivalent efficacy to primary brain-isolated microglia in the treatment of murine syngeneic intracranial malignant gliomas. The ability to generate human microglia facilitates the further study of this important CNS cell type and raises the possibility of their use in personalized medicine applications.

X-linked adrenoleukosdystrophy disease X-ALD

Project description:X-linked adrenoleukodystrophy (X-ALD) is a metabolic genetic disorder of the central nervous system characterized by axonopathy in spinal cords, progressive demyelination in the brain and adrenal insufficiency. Here we provide transcriptomic data from white matter of human X-ALD patients compared to healthy individuals. In particular, from two different disease variants: 1) patients with adrenomyeloneuropathy (AMN) with cerebral demyelination (cAMN) and, 2), an acute, ultimately lethal childhood cerebral form (cALD) featuring severe demyelination in the brain.

Differentiation of human and murine induced pluripotent stem cells to microglia-like cells [human]

Project description:Microglia are myeloid-lineage inflammatory cells that activate innate and adaptive immune responses within the central nervous system (CNS). They also have important roles in CNS development and homeostasis and can modulate the course of a variety of CNS diseases. We report here the sequential differentiation of murine induced pluripotent stem cells (iPSC) into hematopoietic progenitor-like cells and then into cells with a phenotype and gene expression profile resembling that of primary brain-isolated microglia. Functionally, the iPSC-derived microglia (iPS-MG) produce inflammatory cytokines and reactive oxygen species, demonstrate phagocytic activity and migrate to areas of pathology within the brain following intracranial injection. The ability to readily generate iPS-MG in vitro will facilitate the study of normal and disease-specific microglia and be useful for the development of microglia-based treatments for CNS diseases.

Deterministic programming of human pluripotent stem cells into microglia facilitates studying their role in health and disease

Project description:Microglia, the resident immune cells of the central nervous system (CNS), are derived from yolk-sac macrophages that populate the developing CNS during early embryonic development. Once established, the microglia population is self-maintained throughout life by local proliferation. As a scalable source of microglia-like cells (MGLs), we here present a forward programming protocol for their generation from human pluripotent stem cells (hPSCs). The transient overexpression of PU.1 and C/EBPβ in hPSCs led to a homogenous population of mature microglia within 16 d. MGLs met microglia characteristics on a morphological, transcriptional, and functional level. MGLs facilitated the investigation of a human tauopathy model in cortical neuron–microglia cocultures, revealing a secondary dystrophic microglia phenotype. Single-cell RNA sequencing of microglia integrated into hPSC-derived cortical brain organoids demonstrated a shift of microglia signatures toward a more-developmental in vivo–like phenotype, inducing intercellular interactions promoting neurogenesis and arborization. Taken together, our microglia forward programming platform represents a tool for both reductionist studies in monocultures and complex coculture systems, including 3D brain organoids for the study of cellular interactions in healthy or diseased environments.

Derivation of endothelial colony forming cells from human pluripotent stem cells

Project description:Human induced pluripotent stem (hiPS) cells and human embryonic stem (hES) cells differentiate into cells of the endothelial lineage, but derivation of cells with human umbilical cord blood endothelial colony forming cell (ECFC)-like properties has not been reported. Here we describe a novel serum- and stromal cell-free ECFC differentiation protocol for the derivation of clinically relevant numbers of ECFCs (> 108) from hiPS and hES cells. We identified NRP-1+CD31+ selected cells that displayed a stable endothelial phenotype exhibiting high clonal proliferative potential, extensive replicative capacity, formation of human vessels that inosculated with host vasculature upon transplantation, but lacking in teratoma formation in vivo. We also identified NRP-1-VEGF165-KDR-mediated activation of KDR as a critical mechanism for the emergence and derivation of ECFCs from hiPS and hES cells. This protocol advances the field by generating highly replicative but stable endothelial cells for use as a potential cell therapy for human clinical disorders. Transcriptome sequencing of undifferentiated day 0 hiPS cells, Day 3 differentiated hiPS-derived mesoderm proginator cells, Day 12 hiPS-derived NRP-1+CD31+ cells, Day 12 H9-hES-derived NRP-1+CD31+ cells and cord blood-derived Endothelial colony forming cells.
