Texto completoMesenchymal stem or stromal cells (MSCs) are a specific type of adult stem cells with an extensive proliferation and differentiation potential towards specialized cells developing from the mesoderm. MSCs are also characterized by paracrine function through the release of multiple growth factors, chemokines and cytokines. MSCs play as sentinel that feel the microenvironment and act consequently, switching from a pro-inflammatory phenotype to an immunosuppressive phenotype according to the signals they receive. In the present work the existence and the role of MSCs in the pathogenesis and potential therapy of selected gynecological diseases with an inflammatory component as uterine leiomyoma, cervical intraepithelial neoplasia (CIN), and in primary myopathies, as Duchenne Muscular Dystrophy (DMD) were evaluated. In the first study, progenitor cells were identified both in leiomyomas and normal myometrium, and the correlation between these cells and inflammation in leiomyoma onset has been investigated. The data suggest that the upregulation of cytokines related to chronic inflammation in leiomyoma progenitors could favour a microenvironment suitable for the onset of this pathology. In the second study, MSCs from cervix of young (yC-MSCs) and old patients (oC-MSCs) were isolated and results show as their immunobiology is affected by the age of donors, influencing in turn the regression rate of CIN. In addition, in the crosstalk with HeLa cells, yC-MSCs play an anti-tumoral role sustaining an acute inflammatory environment. The goal of the third study was to find a correct strategy to enhance the production of dystrophin protein in DMD through gene therapy. Therefore, myoblasts isolated from DMD donor were transduced with green fluorescent protein (GFP) and a lentiviral vector expressing the snRNA to induce exon skipping; data indicate that transduced myoblasts were able to perform myogenic differentiation expressing a functional dystrophin protein.

Texto completoEpidemiological studies have shown that an increased risk of several cancers, including colon cancer, endometrial, breast, kidney, esophagus, pancreas, gallbladder, liver, and hematological malignancies, is associated with obesity. Moreover, this condition can lead to a reduction in the expected results from treatment, to a worse prognosis and to an increase of the cancer-associated mortality. Several studies have shown that in the white adipose tissue of obese subjects there is a decrease in the maturation of preadipocytes to adipocytes, as well as an imbalance between leptin and adiponectin; in addition, obesity is associated with hyperinsulinemia, hyperglycemia, insulin resistance, aberrant glucose metabolism, chronic inflammation and production of high levels of IGF-1, important risk factor for cancer.
Many studies have highlighted the complexity of the tumors and of their microenvironment. Tumor microenvironment is constituted by several different types of cells as immune system cells, cells of the vascular and lymphatic system (endothelial cells), fibroblasts, pericytes, adipocytes and stromal cells derived from adipose tissue. The role of adipose tissue, and more specifically of adipocytes, in cancer initiation, growth and metastatization is a relatively new area of investigation.
In tumors growing in a microenvironment dominated by adipocytes, it was observed that adipocytes disappear with an accumulation of fibroblast-like cells and subsequent formation of a desmoplastic stroma. Histological observations in some types of cancer, confirm that adipocytes localized at the tumor invasive front, become smaller and the number of fibroblast-like cells increases. It has been hypothesized that fibroblast-like cells could derived from dedifferentiation of adipocytes. In a previous in vitro study with 3T3-L1 cells differentiated to adipocytes, adipocytes promoted the growth, proliferation and survival of human breast cancer cells. However the role of adipocytes in the tumor microenvironment is only incompletely known; in particular in some types of tumors, as melanoma and pancreatic cancer, the role of adipocytes in cancer proliferation and invasiveness is not known. The main focus of this work was to study the interaction between adipocytes and cancer through a co-culture in vitro model. In particular, the study focused on the interaction between adipocytes and human pancreatic cancer cells and human melanoma cells, using a co-culture system between murine fibroblasts 3T3-L1 cell line differentiated to adipocytes and MiaPaca2 and A375 cell line respectively. Adipocytes co-cultured with both types of cells (human pancreatic cancer MiaPaca2 and human melanoma A375 cells) show a progressive loss of lipid content with more centralized nuclei and an elongated shape, similar to the fibroblasts morphology. Moreover, in both co-culture models, dedifferentiated adipocytes loste the adipocyte gene expression profile and acquire a gene profile of reprogramming cells. Finally, MiaPaca2 cells in co-culture showed an up-regulation of Wnt5a and greater activation of STAT3 compared to control; 3T3-L1 cells in co-culture had a greater ability to bind both c-Jun and AP-1, two proteins activated by the Wnt5a pathway; A375 cells in co-culture showed an increased migratory capacity compared to controls and a greater expression of β-catenin and LEF1. The plasticity of AT and the existence of dedifferentiation phenomena could bring new light into the complex relation between obesity, AT dysfunction and increased cancer risk.
