High-Yield Monocyte, Macrophage, and Dendritic Cell Differentiation from Induced Pluripotent Stem Cells

ABSTRACT: Differentiation of induced pluripotent stem cells (iPSC) into monocytes, monocyte-derived macrophages (MDM), and monocyte-derived dendritic cells (moDC) represents a powerful tool for studying human innate immunology and developing novel iPSC-derived immune therapies. Challenges include inefficiencies in iPSC-derived cell cultures, labor-intensive culture conditions, low purity of desired cell types, and feeder cell requirements. Here, a highly efficient method for differentiating monocytes, MDMs, and moDCs that overcomes these challenges is described. The process utilizes commercially-available materials to derive CD34+ progenitor cells that are apically released from a hemogenic adherent fraction (HAF). Subsequently, the HAF gives rise to highly pure (>95%), CD34-CD14+ monocytes in 19-23 days and yields 13.5-fold more monocytes by day 35 when compared to previous methods. These iPSC-monocytes are analogous to human blood-derived monocytes and readily differentiate into MDM and moDC. The efficient workflow and increase in monocyte output heightens feasibility for high throughput studies and enables clinical-scale iPSC-derived manufacturing processes.

Project description:Microarray analysis was carried out on human monocytes (Mono) and monocyte-derived macrophages (MDM) (n = 4 donors) that were subjected to normoxic (N) or hypoxic (H) conditions. Purified human monocytes and their MDM were cultured for 24 h in CSF-1 (5000U/ml) under normoxic or hypoxic conditions.

Production of MHCII-expressing classical monocytes increases during aging in mice and humans

Project description:Aging is associated with increased monocyte production and altered monocyte function. Classical monocytes are heterogenous and a shift in their subset composition may underlie some of their apparent functional changes during aging. We have previously shown that mouse granulocyte-monocyte progenitors (GMPs) produce “neutrophil-like” monocytes (NeuMo), whereas monocyte-dendritic cell progenitors (MDPs) produce monocyte-derived dendritic cell (moDC)-producing monocytes (DCMo). Here, we demonstrate that classical monocytes from the bone marrow of old male and female mice have higher expression of DCMo signature genes (H2-Aa, H2-Ab1, H2-Eb1, Cd74), and that more classical monocytes express MHCII and CD74 protein. Moreover, we show that bone marrow MDPs and classical monocytes from old mice yield more moDC. We also demonstrate higher expression of Aw112010 in old monocytes and that Aw112010 lncRNA activity regulates MHCII induction in macrophages, which suggests that elevated Aw112010 levels may underlie increased MHCII expression during monocyte aging. Finally, we show that classical monocyte expression of MHCII is also elevated during healthy aging in humans. Thus, aging-associated changes in monocyte production may underlie altered monocyte function and have implications for aging-associated disorders.

Monocyte-derived macrophages stimulated with the TLR8 agonist 3M-002 at 10 microM show a prominent activation of TLR-dependent genes as assessed b "Human Toll-like Receptor PCR array pathway" over time

Project description:We were interested in the effects of TLR8 triggering of human monocyte-derived macrophages. We observed a striking upregulation of those genes. This work was done in the context of examining the effects of TLR8 triggering for the activation of HIV. We generated monocyte-derived macrophages (MDM) by initially isolating monocytes and subsequently culturing them in RPMI supplemented with human AB serum. MDM were stimulated for 18 h with the TLR8 agonist 3M-002, and subsequently harvested for extraction of total RNA. Total RNA was then used to quantify the TLR-dependent genes using a PCR array pathway.

Aspergillus fumigatus-derived gliotoxin impairs innate immune cell activation through modulating lipid mediator production in macrophages

Project description:Gliotoxin (GT), a major secondary metabolite and virulence factor of Aspergillus fumigatus, suppresses innate immunity and supports the evasion of host immune responses. Recently, we revealed that GT blocks leukotriene (LT)B4 formation by directly inhibiting LTA4 hydrolase (LTA4H) in activated human neutrophils and monocytes. Here, we elucidated the impact of GT on LTB4 biosynthesis and the complex lipid mediator network in human M1- and M2-like monocyte-derived macrophage (MDM) subtypes and studied the respective consequences for innate immune cell functions. Notably, in resting MDMs, GT elicited prostaglandin and 12/15-lipoxygenase product formation, although less efficient than bacterial exotoxins. In activated MDM, LTB4 formation was effectively suppressed by GT, connected to impaired macrophage phagocytic activity, and detrimental consequences for neutrophil movement and migration. Conclusively, GT impairs functions of activated innate immune cells through suppression of LTB4 formation, while GT may prime the immune system by provoking prostaglandin formation and 12/15-lipoxygenase-derived LM.

Transcriptomic analysis reveals the multifaceted impairments of DC functions produced by a Morbillivirus infection

Project description:Viruses have evolved numerous strategies to impair immunity so that they can replicate more efficiently, such as the immunosuppressive effects of Morbillivirus infection. In the present work we hypothesized that the highly contagious morbillivirus Peste des Petits Ruminants virus (PPRV) could target monocytes and dendritic cells (DC) to contribute to the immunosuppressive effects produced by the infection. Monocytes isolated from healthy sheep donor, a natural host of the disease, could be infected by PPRV and this impaired the differentiation and phagocytic ability of immature monocyte-derived DC (MoDC). Ovine MoDC could be productively infected by PPRV, and this drastically reduced MoDC capacity to activate allogeneic T cell responses. Transcriptomic analysis of infected MoDC indicated that several tolerogenic DC signature genes were upregulated upon PPRV infection.

The miR-424(322)/503 gene cluster regulates pro- vs anti-inflammatory skin DC subset differentiation by modulating TGF-βsignaling

Project description:TGF-β family ligands are key regulators of dendritic cell (DC) differentiation and activation. Epidermal Langerhans cells (LCs) require TGF-β family signaling for their differentiation and canonical TGF-β1 signaling secures a non-activated LC state. LCs reportedly control skin inflammation and are replenished from peripheral blood monocytes, which also give rise to pro-inflammatory monocyte-derived DCs (moDCs). By studying mechanisms in inflammation, we previously screened LCs vs moDCs for differentially expressed miRNAs. miR-424/503 was the most strongly inversely regulated (moDCs > LCs). We found that miR-424/503 is induced during moDC differentiation and promotes moDC differentiation in human and mouse. Inversely, forced repression of miR-424 during moDC differentiation facilitated TGF-β1-dependent LC differentiation. Mechanistically, miR-424/503 deficiency in monocyte/DC precursors leads to the induction of TGF-β1-response genes critical for LC differentiation. Therefore, the miR-424/503 gene cluster plays a decisive role in anti-inflammatory LC vs pro-inflammatory moDC differentiation from monocytes.

RNA sequencing of macrophages derived from monocytes differentiated in presence of M-CSF, GM-CSF and heat killed mycobacteria M. obuense

Project description:Earlier work has shown that macrophages derived from differentiation of monocytes by heat killed (HK) mycobacteria (e.g. M. obuense) exhibit unique immunophenotypic and molecular properties. Yet, our knowledge of these properties is still limited. The goal of the study is to understand global gene expression programs that are differentially modulated in macrophages derived from monocytes that were differentiated through three different routes: in presence of M-CSF, GM-CSF and the heat killed mycobacterium M. obuense. We performed RNA sequencing (RNA-Seq) of monocyte-derived macrophages (MDM) that were acquired from four separate healthy donors and differentiated by incubation with M-CSF (M-MDM), GM-CSF (GM-MDM) and HK M. obuense (Mob-MDM) (n = 12 samples). We report that Mob-MDM exhibit unique gene expression programs that may explain its unique immunophenotypic properties and thus immunomodulatory capacity.
