Identification of regulatory networks in HSCs and their immediate progeny via integrated proteome, transcriptome, and DNA methylome analysis

In this study, we present integrated quantitative proteome, transcriptome, and methylome analyses of hematopoietic stem cells (HSCs) and four multipotent progenitor (MPP) populations. From the characterization of more than 6,000 proteins, 27,000 transcripts, and 15,000 differentially methylated regions (DMRs), we identified coordinated changes associated with early differentiation steps. DMRs show

Inflammation-Induced Emergency Megakaryopoiesis Driven by Hematopoietic Stem Cell-like Megakaryocyte Progenitors

Infections are associated with extensive platelet consumption, representing a high risk for health. However, the mechanism coordinating the rapid regeneration of the platelet pool during such stress conditions remains unclear. Here, we report that the phenotypic hematopoietic stem cell (HSC) compartment contains stem-like megakaryocyte-committed progenitors (SL-MkPs), a cell population that shares

Transcription Factor 7 Limits Regulatory T Cell Generation in the Thymus

Regulatory T cells (Tregs) differentiate in the thymus, but the mechanisms that control this process are not fully understood. We generated a comprehensive quantitative and differential proteome of murine Tregs and conventional T cells. We identified 5225 proteins, 164 of which were differentially expressed in Tregs. Together with the comparative analysis of proteome and gene expression data, we i

Transcriptome-wide profiling and posttranscriptional analysis of hematopoietic stem/progenitor cell differentiation toward myeloid commitment

Hematopoietic stem cells possess lifelong self-renewal activity and generate multipotent progenitors that differentiate into lineage-committed and subsequently mature cells. We present a comparative transcriptome analysis of ex vivo isolated mouse multipotent hematopoietic stem/progenitor cells (Lin(neg)SCA-1(+)c-KIT(+)) and myeloid committed precursors (Lin(neg)SCA-1(neg)c-KIT(+)). Our data displ

Proteomic analysis of cell fate decision

The field of proteomics is progressing at a rapid pace, developing from primarily a specialist technology to a valuable tool in biological research. Importantly, the establishment of mass spectrometry as a quantitative method, miniaturisation of liquid chromatography techniques, and improved sensitivity of mass-spectrometric instrumentation now enable near-complete monitoring of cellular proteome

Similar, yet different: a comparative analysis of the role of trust in radical and incremental product innovation

Trust within teams is a central performance driver in product innovation. In this paper, we examine the antecedents to and performance implications of trust in firms engaged in radical innovation compared to those working towards incremental innovations. Our findings suggest that systematic processes and structures are significantly linked to trust in firms conducting radical innovation, but not s

Good cop-bad cop : Trust, control, and the lure of integration

Based on a longitudinal case study of four interorganizational product development collaborations, this paper identifies a lure to cross-functional integration that has hereto been neglected. In particular, findings suggest that when the buyer firm separates the Research and Development (R&D) Department from the Procurement Department, the two departments play a good cop-bad cop strategy towar

Creativity, trust and systematic processes in product development

This paper addresses the challenge of striking a balance between, on one hand, mitigating uncertainty through the existence of systematic processes and structures and, on the other, stimulating creativity through allowable variation in work processes and structures. Both objectives are fundamental aspects of product development work. Our main finding is that both objectives can be achieved simulta

Advances in ethanol production from hardwood spent sulphite liquors

Hardwood spent sulphite liquors (HSSLs) are by-products from the pulping industry rich in pentoses, which are not yet fully exploited for bioprocessing, namely for the production of bioethanol. The sustainable fermentation of pentoses into bioethanol is a challenge to overcome. Besides sugars, HSSLs contains inhibitors that decrease the possibility of bioprocessing of these by-products. Neverthele

Moral Development, Friendship and Self-deception in Dame Margaret Drabble’s The Millstone

Dame Margaret Drabble’s The Millstone can profitably be read as shedding light on personal identity and moral development as well as how these connect to contemporary society, history, friendship, self-knowledge and self-deception in a way that ought to be of interest to classic perfectionist theories, i.e. ethical theories that develop an account of ethics informed by an account of the good human

The Ambiguities of Recognition : Young Queer Sexualities in Contemporary India

What does recognition mean for people whose sexuality has for a long time been criminalised? Over the last years, the recognition of India’s queers has been the focus of numerous contestations as a result of the complex developments around Section 377 of the Indian Penal Code, which criminalises ‘carnal acts against the order of nature’. The Section had been partially repealed in 2009 by the Delhi
