Fibronectin is a component of the extracellular matrix that links collagen fibers to integrins on the cell's surface. The splicing isoforms, containing the ED-B domain, are not expressed in adult tissues but only in tumor stroma or during embryonic development. Fibroblasts and endothelial cells express ED-B fibronectin during angiogenesis. Also cancer cells can synthetize ED-B fibronectin, but its function in tumor growth needs to be further elucidated.We evaluated the expression of ED-B fibronectin in prostate cancer cell lines: PC3 and DU145...

Adhesion is a key component of hematopoietic stem cell regulation mediating homing and retention to the niche in the bone marrow. Here, using an RNA interference screen, we identify cytohesin 1 (CYTH1) as a critical mediator of adhesive properties in primary human cord-blood derived hematopoietic stem and progenitor cells (HSPCs). Knockdown of CYTH1 disrupted adhesion of HSPC to primary human mesenchymal stroma cells (MSCs). Attachment to fibronectin and ICAM1, two integrin ligands, was severely impaired, and CYTH1 deficient cells showed a reduced integrin β1 activation response, suggesting that CYTH1 mediates integrin-dependent functions...

The role of mesenchymal stem cells (MSC) in osteosarcoma (OS), the most common primary tumor of bone, has not been extensively elucidated. We have recently shown that OS is characterized by interstitial acidosis, a microenvironmental condition that is similar to a wound setting, in which mesenchymal reactive cells are activated to release mitogenic and chemotactic factors. We therefore intended to test the hypothesis that, in OS, acid-activated MSC influence tumor cell behavior. Conditioned media or co-culture with normal MSC previously incubated with short-term acidosis (pH 6...

BACKGROUND: Hyaluronan synthases (HAS) control the biosynthesis of hyaluronan (HA) and critically modulate the tumor microenviroment. Cancer-associated fibroblasts (CAFs) affect the progression of a tumor by remolding the matrix. However, little is known about the role of HAS from CAFs in this process. This study aimed to determine the role of hyaluronan synthase 2 (HAS2) from CAFs in the progression of oral squamous cell carcinoma (OSCC) invasion. METHODS: HAS isoforms 1, 2, and 3 in paired sets of CAFs and normal fibroblasts (NFs) were examined by real-time PCR, and the expression of HAS2 and α-SMA in OSCC tissue sections was further evaluated using immunohistochemical staining...

Hedgehog(HH) pathway is found to be activated through a manner of canonical, or the non-canonical HH pathways. Distinct hyperplasia stroma around tumor cells is supposed to express pro-inflammatory cytokines abundantly, such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β), etc. in pancreatic ductal adenocarcinoma (PDAC) tissues. In this study we observed the effects of TNF-α and IL-1β on HH pathway activation in PDAC cells, and explored their activation manners. Our results showed that pro-inflammatory cytokines, TNF-α and IL-1β, could up-regulate the expression of GLI1 gene, increase its nuclear protein expression and promote malignant cell behaviors including migration, invasion, epithelial-mesenchymal transition (EMT) and drug resistance as well...

Ductal carcinoma in situ (DCIS) refers to neoplastic epithelial cells proliferating within the mammary ducts of the breast, which have not breached the basement membrane nor invaded surrounding tissues. Traditional thinking holds that DCIS represents an early step in a linear progression towards invasive ductal carcinoma (IDC). However, as only approximately half of DCIS cases progress to IDC, important questions around the key determinants of malignant progression need to be answered. Recent studies have revealed that molecular differences between DCIS and IDC cells are not found at the genomic level; instead, altered patterns of gene expression and post-translational regulation lead to distinct transcriptomic and proteomic profiles...

The apparent lack of classical mechanisms for maternal recognition of pregnancy is one of the most intriguing features of canine reproduction. Consequently, similar levels of circulating luteal steroids are observed in pregnant and non-pregnant dogs. However, the early pre-implantation canine embryo locally modulates uterine responses to its presence, facilitating the successful onset of pregnancy. As a part of this interaction, the canine uterus undergoes a species-specific decidualization. Maternal stroma-derived decidual cells develop, the only cells of the canine placenta expressing progesterone receptor (PGR)...

: Thyroid fibromatosis is a very rare lesion; to our knowledge, there are only four cases reported in the medical literature. Herein, we report the clinical case of a woman with thyroid fibromatosis with a long follow-up (11 years). A 63-year-old female patient, with an increasing multinodular goitre without compressive symptoms, was admitted to total thyroidectomy. The histology revealed a spindle-cell proliferation with fibroblastic characteristics with no atypia and thin capillary vessels...

Osteosarcoma (OS) is an aggressive bone malignancy with a high relapse rate despite combined treatment with surgery and multiagent chemotherapy. As for other cancers, OS-associated microenvironment may contribute to tumor initiation, growth, and metastasis. We consider mesenchymal stromal cells (MSC) as a relevant cellular component of OS microenvironment, and have previously found that the interaction between MSC and tumor cells is bidirectional: tumor cells can modulate their peripheral environment that in turn becomes more favorable to tumor growth through metabolic reprogramming...

Accumulating evidence has demonstrated that menstrual blood stands as a viable source of stem cells. Menstrual blood-derived stem cells (MenSCs) are morphologically and functionally similar to cells directly extracted from the endometrium, and present dual expression of mesenchymal and embryonic cell markers, thus becoming interesting tools for regenerative medicine. Functional reports show higher proliferative and self-renewal capacities than bone marrow-derived stem cells, as well as successful differentiation into hepatocyte-like cells, glial-like cells, endometrial stroma-like cells, among others...

Tumor budding is thought to reflect the epithelial-mesenchymal transition (EMT). However, the molecular mechanism linking tumor buds and the EMT remains unclear. Here, we examined the induction of tumor budding and EMT and their association with EMT-related proteins (ZEB1, TWIST, SNAIL and SLUG) in colorectal cancer (CRC). Immunohistochemical expression of pan-cytokeratin was examined for identification of tumor budding in 101 CRCs. Grading of tumor budding was classified into low and high grade groups. Tissue micro-array was conducted to identify tumor budding sites...

Superficial acral fibromyxoma (SAF) is an uncommon benign dermal mesenchymal lesion of adults with predilection for acral sites, in particular the nail region. To date, <300 cases have been reported. SAFs consistently express CD34 but other diagnostic markers or specific genetic alterations have not been established yet. We describe 11 SAFs occurring in 7 males and 4 females aged 37 to 86years (median, 48). Mean size was 6mm (range, 4-20mm). Affected sites were fingers (n=5), toes (n=3), heel (n=1), calf (n=1) and unspecified digit (n=1)...

We report a case of two peculiar gallbladder polyps in a sixty-four year old male who presented with symptomatic cholelithiasis. Cholecystectomy was performed, which revealed two polyps measuring 0.6 cm and 1.9 cm, located in the body of the gallbladder. Microscopic examination of the polyps showed composite mesenchymal lesions with vascular proliferation of small-to-medium sized arterioles, myoid stroma, and lipomatous periphery. The myoid component was characterized by wisps of bland smooth muscle fibers loosely separated by proteinaceous and focally myxoid matrix...

PURPOSE: Cytokine or chemokine networks involve lymphatic and distant metastasis of various malignancies, including oral squamous cell carcinoma (OSCC). Immunohistochemical analysis was used to investigate the contribution of the axis of the CC chemokine receptor-2 (CCR2) and the CC chemokine receptor-2 ligand (CCL2) to lymphatic metastasis, particularly the relation between primary OSCC and marginal sinus histiocytosis in regional lymph nodes. MATERIALS AND METHODS: Thirteen metastasis-free cases, 15 metastatic cases at resection of primary tumor resection, and 13 postresection metastasis cases were examined...

BACKGROUND: The terminal duct lobular unit (TDLU) is the most dynamic structure in the human breast and the putative site of origin of human breast cancer. Although stromal cells contribute to a specialized microenvironment in many organs, this component remains largely understudied in the human breast. We here demonstrate the impact on epithelium of two lineages of breast stromal fibroblasts, one of which accumulates in the TDLU while the other resides outside the TDLU in the interlobular stroma...

Historically, the word cancer is derived from the Latin cancer, as the red swollen arteries near a tumor reminded the physician Galenus and his fellow Romans of a red crab. Currently, cancer remains the disease to beat as it remains a leading cause of death worldwide (WHO). Tumors do not simply consist out of cancer cells, as they can recruit normal cells, which will form the tumor-associated stroma. These stromal cells together with the extracellular matrix, constitute the tumor microenvironment. Reciprocal communication between tumor-associated stromal cells and cancer cells is important for the induction of epithelial-to-mesenchymal transition and invasion...

Therapeutic inhibition of macroautophagy/autophagy is expected to increase chemosensitivity of cancers and alter tumor-stroma interdependence. The hypoxic, metabolically challenged bone marrow microenvironment confers chemoresistance to leukemia cells. The impact of autophagy inhibition in the context of microenvironment-mediated resistance in leukemia is less explored. Our recent studies demonstrated that co-culture of acute myelogenous leukemia (AML) cells with marrow-derived mesenchymal stromal cells (MSC) induces autophagy in AML cells and increases resistance to genotoxic agents (cytarabine and idarubicin)...

: Previous observations that human amniotic fluid cells (AFC) can be transformed by human adenovirus type 5 (HAdV-5) E1A/E1B oncogenes prompted us to identify the target cells in the AFC population that are susceptible for transformation. Our results demonstrate that one cell type corresponding to mesenchymal stem/stroma cells (hMSC), can be reproducibly transformed by HAdV-5 E1A/E1B oncogenes as efficient as primary rodent cultures. HAdV-5 E1-transformed hMSCs exhibit all properties commonly associated with a high grade of oncogenic transformation, including enhanced cell proliferation, anchorage-independent growth, increased growth rate, high telomerase activity as well as numerical and structural chromosomal aberrations...

Risk factors for pancreatic ductal adenocarcinoma (PDAC) progression after surgery are unclear, and additional prognostic factors are needed to inform treatment regimens and therapeutic targets. PDAC is characterized by advanced sclerosis of the extracellular matrix, and interactions between cancer cells, fibrillar collagen, and other stromal components play an integral role in progression. Changes in stromal collagen alignment have been shown to modulate cancer cell behavior and have important clinical value in other cancer types, but little is known about its role in PDAC and prognostic value...
