Abstract:
Since its first conceptualization over a century ago, the mesenchymal phenotype has traditionally been viewed as either a transient phase between successive epithelial stages or as a feature of cell types primarily devoted to structural support. However, recent findings in cancer research challenge this limited view, demonstrating that mesenchymal traits and hybrid mesenchymal/epithelial states can mark cancer cells with stem cell properties. By analyzing publicly available single-cell transcriptome datasets from early embryonic stages and adult tissues, this study aims to extend this concept

Undifferentiated mesenchymal cells were isolated from mouse embryonic lungs and plated at subconfluent and confluent densities. During the first 5 hours in culture, all the cells were negative for smooth muscle markers. After 24 hours in culture, the mesenchymal cells that spread synthesized smooth muscle alpha-actin, muscle myosin, desmin and SM22 in levels comparable to those of mature smooth muscle. The cells that did not spread remained negative for smooth muscle markers. SM differentiation was independent of cell-cell contact or proliferation. In additional studies, undifferentiated lung

AbstractBackground: Human embryonic stem (hES) cells are pluripotent, and can differentiate into three germ layers. Traditionally, cultures of hES cells are maintained in a system containing mouse embryonic fibroblasts as a feeder layer for support of undifferentiated growth. However, contamination by animal cells limits the use of hES cells.Objective: We evaluated the use of human dental pulp stem cells (hDPSCs) as a feeder layer for hES cell culture. It should be possible to obtain a new source of human mesenchymal stem cells for feeder cells to maintain undifferentiated growth of hES cells.

Abstract:
Undifferentiated embryonic mesenchymal cells are round/cuboidal in shape. During development, visceral myogenesis is shortly preceded by mesenchymal cell elongation. To determine the role of the cell's shape on smooth muscle development, undifferentiated embryonic mesenchymal cells from intestine (abundant visceral muscle), lung (some visceral muscle) or kidney (no visceral muscle) were plated under conditions that maintained cell rounding or promoted elongation. Regardless of their fate in vivo, all the cells differentiated into smooth muscle upon elongation as indicated by the expression of

Abstract Ependymoma (EPN) is a brain tumor commonly presenting in childhood that remains fatal in the majority of children. Intra-tumoral cellular heterogeneity in bulk-tumor samples significantly confounds our understanding of EPN biology, impeding development of effective therapy. We therefore used single-cell RNA sequencing to catalog cellular heterogeneity of 26 childhood EPN, predominantly from ST-RELA, PFA1 and PFA2 subgroups. ST-RELA and PFA subgroups clustered separately, with ST-RELA clustering largely according to individual sample-of-origin. PFA1 and PFA2 subgroup EPNs cells were in

SummaryThe digestive tract and the gut as a paradigm represents an attractive system for the study of mechanisms involved in the differentiation of two types of progenitor cells: the endodermal cells during embryonic life and the undifferentiated crypt cells during epithelial renewal of the adult intestine. The morphological and functional events that accompany the differentiation processes of progenitor cells into the polarized epithelial cell types characteristic of the intestine appear comparable in both situations (1,2).

Aberrant activation of histone deacetylases (HDACs) is one of the causes of tumor cell transformation in many types of cancer, however, the critical HDAC responsible for the malignant transformation remain unclear. To identify the HDAC related to the dedifferentiation of hepatocellular carcinoma (HCC) cells, we investigated the expression profile of HDACs in differentiated and undifferentiated hepatoma cells. We found that HDAC9, a member of the class II HDAC, is preferentially expressed in undifferentiated HCC cells. Analysis of 373 HCC patients in The Cancer Genome Atlas (TCGA) database reve

The body of work presented in this dissertation has demonstrated that the interactions between donor cells and host cells are critical for bone repair and regeneration. The donor cells secrete VEGF which activates the downstream PI3K/Akt signaling pathway, ultimately leading to host cell recruitment and robust bone regeneration. The findings from this dissertation may provide a scientific rationale for the development of novel therapeutic strategies in the treatment and management of bone defects.

Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune inflammatory disorder with considerable clinical heterogeneity and a prevalence of 26 to 52 out of 100,000. In autoimmune diseases, such as SLE, the immune system loses its ability to distinguish between self and other. Treatment of SLE is challenging because of clinical heterogeneity and unpredictable disease flares. Currently available treatments, such as corticosteroids, cyclophosphamide (CYC), and other immunosuppressive or immunomodulating agents, can control most lupus flares but a definitive cure is rarely achieved.
