Glioblastomas exhibit a hierarchical cellular organization, suggesting that they are driven by neoplastic stem cells that retain partial yet abnormal differentiation potential. Here, we show that a large subset of patient-derived glioblastoma stem cells (GSCs) express high levels of Achaete-scute homolog 1 (ASCL1), a proneural transcription factor involved in normal neurogenesis. ASCL1(hi) GSCs exhibit a latent capacity for terminal neuronal differentiation in response to inhibition of Notch signaling, whereas ASCL1(lo) GSCs do not...

Direct lineage reprogramming, including with small molecules, has emerged as a promising approach for generating desired cell types. We recently found that during chemical induction of induced pluripotent stem cells (iPSCs) from mouse fibroblasts, cells pass through an extra-embryonic endoderm (XEN)-like state. Here, we show that these chemically induced XEN-like cells can also be induced to directly reprogram into functional neurons, bypassing the pluripotent state. The induced neurons possess neuron-specific expression profiles, form functional synapses in culture, and further mature after transplantation into the adult mouse brain...

Dormant hematopoietic stem cells (dHSCs) display superior serial reconstitution capacity compared to active HSCs, although their role in normal hematopoiesis has not been thoroughly investigated. Recently in Cell, Cabezas-Wallscheid et al. (2017) demonstrate involvement of retinoic acid signaling in murine dHSCs for preservation of the HSC pool.

Several cell populations have been reported to possess intestinal stem cell (ISC) activity during homeostasis and injury-induced regeneration. Here, we explored inter-relationships between putative mouse ISC populations by comparative RNA-sequencing (RNA-seq). The transcriptomes of multiple cycling ISC populations closely resembled Lgr5(+) ISCs, the most well-defined ISC pool, but Bmi1-GFP(+) cells were distinct and enriched for enteroendocrine (EE) markers, including Prox1. Prox1-GFP(+) cells exhibited sustained clonogenic growth in vitro, and lineage-tracing of Prox1(+) cells revealed long-lived clones during homeostasis and after radiation-induced injury in vivo...

Podocyte depletion drives kidney disease and kidney failure progression, but podocyte complexity at the glomerular filtration barrier is difficult to model in vitro. In Nature Biomedical Engineering, Musah et al. (2017) developed a multifluidic device with iPS-derived podocytes mimicking a functional glomerular filtration barrier that elevates standards for modeling glomerular diseases.

The intestinal epithelium displays great resilience, as several cell populations can replenish the stem cell pool upon damage. Two studies in Cell Stem Cell extend this capacity to enteroendocrine cells, addressing the molecular basis underlying cellular plasticity observed in the intestine and the identities of putative reserve stem cells.

The ability to directly reprogram mature cells to alternative fates challenges concepts of how cell identities are maintained, erased, and acquired. Recent advances in understanding and overcoming hurdles to direct neuronal conversion have provided new insights into mechanisms that maintain cell identity programs and have enabled high efficiency reprogramming in vivo. We discuss key cell-intrinsic molecular and metabolic constraints that influence the establishment of a new identity as well as environmental inputs from injured brains that favor or harm the conversion process...

Nonclinical studies of drug effects with human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) provide new possibilities for evaluating drug safety and efficacy. The Comprehensive In Vitro Proarrhythmia Assay (CiPA) paradigm provides lessons from the cardiac field that also apply to drug studies with other stem cell-based assays.

George Daley and Shahin Rafii's groups recently generated multilineage, serially engrafting hematopoietic stem cells (HSCs) from human pluripotent stem cells and endothelial cells, respectively, achieving an important research milestone for the field. We asked some experts in the field to reflect on the broader implications of these findings.

Screening for small molecules or drugs that can protect or restore mechanosensory hair cells has been hampered by limited cell numbers. In Nature Biotechnology, Koehler et al.

Organ growth requires a careful balance between stem cell self-renewal and lineage commitment to ensure proper tissue expansion. The cellular and molecular mechanisms that mediate this balance are unresolved in most organs, including skeletal muscle. Here we identify a long-lived stem cell pool that mediates growth of the zebrafish myotome. This population exhibits extensive clonal drift, shifting from random deployment of stem cells during development to reliance on a small number of dominant clones to fuel the vast majority of muscle growth...

Lung tissue can robustly regenerate functional alveolar units after injury, but the mechanisms are unknown. Lechner et al. (2017) in this issue of Cell Stem Cell demonstrate that lung regeneration is facilitated by bone-marrow-derived myeloid cells that are recruited to the lung through a CCL2-CCR2 chemokine axis and by IL-13 expressing innate lymphoid cells.

Gastric and small intestinal organoids differentiated from human pluripotent stem cells (hPSCs) have revolutionized the study of gastrointestinal development and disease. Distal gut tissues such as cecum and colon, however, have proved considerably more challenging to derive in vitro. Here we report the differentiation of human colonic organoids (HCOs) from hPSCs. We found that BMP signaling is required to establish a posterior SATB2+ domain in developing and postnatal intestinal epithelium. Brief activation of BMP signaling is sufficient to activate a posterior HOX code and direct hPSC-derived gut tube cultures into HCOs...

Replicating Lgr5(+) stem cells and quiescent Bmi1(+) cells behave as intestinal stem cells (ISCs) in vivo. Disrupting Lgr5(+) ISCs triggers epithelial renewal from Bmi1(+) cells, from secretory or absorptive progenitors, and from Paneth cell precursors, revealing a high degree of plasticity within intestinal crypts. Here, we show that GFP(+) cells from Bmi1(GFP) mice are preterminal enteroendocrine cells and we identify CD69(+)CD274(+) cells as related goblet cell precursors. Upon loss of native Lgr5(+) ISCs, both populations revert toward an Lgr5(+) cell identity...

Functionally relevant markers of glioblastoma stem-like cells (GSCs) have potential for therapeutic targeting to treat this aggressive disease. Here we used generation and screening of thousands of monoclonal antibodies to search for receptors and signaling pathways preferentially enriched in GSCs. We identified integrin α7 (ITGA7) as a major laminin receptor in GSCs and in primary high-grade glioma specimens. Analyses of mRNA profiles in comprehensive datasets revealed that high ITGA7 expression negatively correlated with survival of patients with both low- and high-grade glioma...

To investigate the role of immune cells in lung regeneration, we used a unilateral pneumonectomy model that promotes the formation of new alveoli in the remaining lobes. Immunofluorescence and single-cell RNA sequencing found CD115+ and CCR2+ monocytes and M2-like macrophages accumulating in the lung during the peak of type 2 alveolar epithelial stem cell (AEC2) proliferation. Genetic loss of function in mice and adoptive transfer studies revealed that bone marrow-derived macrophages (BMDMs) traffic to the lung through a CCL2-CCR2 chemokine axis and are required for optimal lung regeneration, along with Il4ra-expressing leukocytes...

Tissue homeostasis requires the production of newly differentiated cells from resident adult stem cells. Central to this process is the expansion of undifferentiated intermediates known as transit-amplifying (TA) cells, but how stem cells are triggered to enter this proliferative TA state remains an important open question. Using the continuously growing mouse incisor as a model of stem cell-based tissue renewal, we found that the transcriptional cofactors YAP and TAZ are required both to maintain TA cell proliferation and to inhibit differentiation...
