Abstract Systemic Sclerosis (SSc) or Scleroderma is a chronic autoimmune disease where immune cells contribute to the initiation and/or progression of microvascular damage and fibrosis, leading devastating tissue malfunction often resulting in high morbidity mortality. We recently discovered that PBMCs from SSc patients show increased expression various co-inhibitory receptors, consistent with ...

Two cell lines with different in vitro growth patterns were established from the pleural fluid of a patient with malignant epithelial pleural mesothelioma. The cell line established in RPMI 1640 supplemented with human AB serum had an epithelial morphology, while the cell line established in fetal calf serum-supplemented medium had a fibroblast-like morphology. Exposure of the fibroblast-like c...

Mitotic inhibitors (colcemid, colchicine, and vinblastine) initiate DNA synthesis in dense stationary cultures of mouse embryo fibroblast-like cells. This initiation is not due to any changes in local cell population density. Relationships between the activation of proliferation and other changes of interphase fibroblast-like cells produced by the mitotic inhibitors (disappearance of cytoplasmi...

Background: The aim of this study was to investigate the effect of methanolic extract of Achillea millefolium L. (MEA) on the antiproliferative activity of bleomycin on human prostate cancer and normal skin cells. Materials and Methods: Human prostate cancer cell (DU-145) and human non-malignant fibroblast cell (HFFF2) were treated with MEA at various concentrations ( 20, 100, 500, 1000 and ...

A convenient synthesis of indolin-2-ones substituted in the 3 position by an aminomethylene group bearing different amino acid moieties is described. Their antiproliferative activities were evaluated toward a panel of human solid tumor cell lines (PC 3, DLD-1, MCF-7, M4 Beu, A549, PA 1) and healthy cell lines (a murine fibroblast L929 and a human fibroblast primary culture).

introduction: mineral trioxide aggregate is being widely used for root end filling, pulp capping, perforation repair, and other endodontic procedures. recently, a material similar to proroot mineral trioxide aggregate (pmta) was developed in iran named root mineral trioxide aggregate (rmta) with the claim of having the exact result of original mta. the purpose of this study was to compare the a...

Human activated T cells adhere to synovial fibroblast-like cells in vitro. The present study was conducted to investigate the consequences of T cell-synovial fibroblast interactions with regard to induction of adhesion molecules and proinflammatory cytokines. A sensitive Western blot technique, polymerase chain reaction (PCR) amplification, and fluorescence-activated cell sorter (FACS) analysis...

Endometrial cancer is the most commonly diagnosed gynecologic malignancy worldwide; yet the tumor microenvironment, especially the fibroblast cells surrounding the cancer cells, is poorly understood. We established four primary cultures of fibroblasts from human endometrial cancer tissues (cancer-associated fibroblasts, CAFs) using antibody-conjugated magnetic bead isolation. These relatively h...

Semaphorin-7A is a glycosylphosphatidylinositol-anchored protein, initially characterized as an axon guidance protein. Semaphorin-7A also contributes to immune cell regulation and may be an essential pro-fibrotic factor when expressed by non-fibroblast cell types (exogenous). In mouse models, semaphorin-7A was shown to be important for TGF-ß1-induced pulmonary fibrosis characterized by myofibro...

Biologic drugs have revolutionised outcomes in psoriasis, with a growing number of patients achieving clear skin (‘remission’). However, treatment involves expensive regular injections, and the long-term impact remains uncertain. An improved understanding early mechanisms underpinning biologics-induced remission may help inform strategies around drug withdrawal. This promises to overcome burden...
