The contribution of transcriptional and post-transcriptional regulation to modifying carbon allocation to developing wood of trees is not well defined. To clarify the role of transcriptional regulation, the enzyme activity patterns of eight central primary metabolism enzymes across phloem, cambium, and developing wood of aspen (Populus tremula L.) were compared with transcript levels obtained by RNA sequencing of sequential stem sections from the same trees. Enzymes were selected on the basis of their importance in sugar metabolism and in linking primary metabolism to lignin biosynthesis...

Squamous cell carcinoma (SCC) is the sixth most frequent malignant tumor of the head and neck region. Despite advances in therapeutic options over the last decades, the rate of mortality and morbidity has not been improved markedly. A small subset of cells, cancer stem cells (CSCs), with self-renewal properties have become a major focus of current cancer research. CD44 and p63 are identified as candidate stem cell markers in normal squamous epithelium and SCC. The role of these markers in oral squamous cell carcinoma (OSCC) is still debatable...

The generation of induced pluripotent stem cells (iPSCs) and differentiation to cells composing major organs has opened up the possibility for a new model system to study adverse toxicities associated with chemotherapy. Therefore, we used human iPSC-derived neurons to study peripheral neuropathy, one of the most common adverse effects of chemotherapy and cause for dose reduction. To determine the utility of these neurons in investigating the effects of neurotoxic chemotherapy, we measured morphological differences in neurite outgrowth, cell viability as determined by ATP levels and apoptosis through measures of caspase 3/7 activation following treatment with clinically relevant concentrations of platinating agents (cisplatin, oxaliplatin and carboplatin), taxanes (paclitaxel, docetaxel and nab-paclitaxel), a targeted proteasome inhibitor (bortezomib), an antiangiogenic compound (thalidomide), and 5-fluorouracil, a chemotherapeutic that does not cause neuropathy...

Inhibition of the tumorigenic potential of human pluripotent stem cells (hPSCs) remains critically important for safe hPSC-based therapy. In this issue of Cell Chemical Biology, Kuang et al. (2017) reveal that the phospho-D-peptide D-3 efficiently induces death of residual hPSCs, but not of differentiated progenies, through high alkaline phosphatase activity in hPSCs.

The rapid turnover of intestinal epithelial cells is maintained by a small number of stem cells located in pocket-like gland structures called crypts. While our understanding of the identity and function of intestinal stem cells (ISCs) has rapidly progressed, epigenetic and transcriptional regulation in crypt stem cell and progenitor pools remains an active field of investigation. Surrounded by various types of cells in the stroma, crypt progenitors display high levels of plasticity, harboring the ability to interconvert in the face of epithelial damage...

Sirtuins are pleiotropic NAD+ dependent histone deacetylases involved in metabolism, DNA damage repair, inflammation and stress resistance. SIRT6, a member of the sirtuin family, regulates the process of normal aging and increases the lifespan of male mice over-expressing Sirt6 by 15%. Neurogenesis, the formation of new neurons within the hippocampus of adult mammals, involves several complex stages including stem cell proliferation, differentiation, migration and network integration. During aging, the number of newly generated neurons continuously declines, and this is correlated with a decline in neuronal plasticity and cognitive behavior...

The concept of moral distress was defined in 1984 as (a) the psychological distress of (b) being in a situation in which one is constrained from acting (c) on what one knows to be right. A substantial literature on the subject has developed, primarily in nursing ethics. The aforementioned elements of distress are applied here to areas of clinical and organizational significance: (a) distress from causing intimate pain during care of the dying, (b) constraints stemming from proximate and background challenges of health care organizations, and (c) changing perspectives on therapeutic technologies derived from global environmental perspectives...

Purpose T-cell-replete HLA-haploidentical donor hematopoietic transplantation using post-transplant cyclophosphamide was originally described using bone marrow (BM). With increasing use of mobilized peripheral blood (PB), we compared transplant outcomes after PB and BM transplants. Patients and Methods A total of 681 patients with hematologic malignancy who underwent transplantation in the United States between 2009 and 2014 received BM (n = 481) or PB (n = 190) grafts. Cox regression models were built to examine differences in transplant outcomes by graft type, adjusting for patient, disease, and transplant characteristics...

The role of Ras signaling during tooth development is poorly understood. Ras proteins-which are activated by many upstream pathways, including receptor tyrosine kinase cascades-signal through multiple effectors, such as the mitogen-activated protein kinase (MAPK) and PI3K pathways. Here, we utilized the mouse incisor as a model to study how the MAPK and PI3K pathways regulate dental epithelial stem cells and amelogenesis. The rodent incisor-which grows continuously throughout the life of the animal due to the presence of epithelial and mesenchymal stem cells-provides a model for the study of ectodermal organ renewal and regeneration...

Evidence of cancer cells that bear attributes analogous to those of normal stem cells has developed a hierarchical model of cancer's architecture and progression. This subset of cancer stem cells (CSCs) drives the progression and therapy resistance of cancers. Research to identify the phenotypes of these CSCs presents evidence of a subpopulation that is more resistant to therapy and may proliferate in response. Literature shows that CSCs typically represent around 1%-10% of cell populations in head and neck cancer but this proportion may increase in response to a therapeutic radiation dose...

Nuclear magnetic resonance (NMR) is a fundamental spectroscopic technique for the study of biological systems and materials, molecular imaging and the analysis of small molecules. It detects interactions at very low energies and is thus non-invasive and applicable to a variety of targets, including animals and humans. However, one of its most severe limitations is its low sensitivity, which stems from the small interaction energies involved. Here, we report that dynamic nuclear polarization in liquid solution and at room temperature can enhance the NMR signal of (13)C nuclei by up to three orders of magnitude at magnetic fields of ∼3 T...

As one of the least studied bone morphogenetic proteins (BMPs), BMP9 is highly capable of promoting osteogenic differentiation. However, the underlying mechanism involved remains largely unknown. Recent studies have demonstrated that RUNX1 (runt-related transcription factor 1) is essential in osteoblast/chondrocyte maturation. In this study, we investigated the function of RUNX1 in BMP9-induced osteogenic of murine mesenchymal stem cell line (C3H10T1/2) and murine multi-lineage cell lines (C2C12 and MEFs). Our data showed that BMP9 promoted the endogenous expression of RUNX1 in C3H10T1/2, C2C12 and MEFs...

Hepatic sinusoidal obstruction syndrome (previously named veno-occlusive disease, SOS/VOD) is a serious complication of allogeneic stem cell transplantation (HSCT). Early identification of patients at risk of SOS/VOD may possibly improve the outcome and reduce mortality. Rotation thromboelastometry (ROTEM) is global assay allowing for the precise assessment of both bleeding and thrombotic conditions, however, its usefulness in patients undergoing HSCT for acute leukaemia has not been studied.We evaluated the thromboelastometry parameters in patients undergoing allogeneic HSCT for acute leukaemia to identify candidate biomarkers of SOS/VOD occurrence...

BACKGROUND: Porphyromonas gingivalis (Pg) is a major periodontal pathogen that contains immunostimulatory components. Periodontal ligament mesenchymal stem cells (PDLSCs) are responsible for regeneration of the periodontium that is lost due to periodontitis. Pathologic factors within the microenvironment that impair resident PDLSCs are not well understood. The present study investigated in vitro the effects of Pg protein extract (PgPE) on the biological properties of CD105-enriched PDL progenitor cell populations (PDL-CD105(+) cells)...

In order to assess the therapeutic potential of cell-based strategies, it is of paramount importance to elaborate and validate tools for monitoring the behavior of injected cells in terms of tissue dissemination and engraftment properties. Here, we apply Bismuth Ferrite harmonic nanoparticles (BFO HNPs) to \textit{in vitro} expanded human skeletal muscle-derived stem cells (hMuStem cells), an attractive therapeutic avenue for patients suffering from Duchenne Muscular Dystrophy (DMD). We demonstrate the possibility of stem cell labeling with HNPs...
