Exposure to free silica induces silicosis and myofibroblasts are regarded as primary effector cells. Fibrocytes can differentiate into myofibroblast. Therefore, the present study was designed to investigate whether fibrocytes participate in silicosis. The rat model of silicosis was established. Hematoxylin-eosin stainings and Masson stainings were used to evaluate the histopathology and collagen deposition. Flow cytometry and immunofluorescence were performed to detect the number of fibrocytes and their contribution to myofibroblasts...

Human CD34+ fibrocytes, circulating monocyte lineage progenitor cells, have recently been implicated in thyroid-associated ophthalmopathy (TAO), the ocular manifestation of Graves' disease (GD). Fibrocytes express constitutive MHC class II (MHC-2) and, surprisingly, thyroglobulin (Tg) and functional thyrotropin (TSH) receptor (TSHR). Underlying expression of these thyroid proteins is the autoimmune regulator protein (AIRE). Fibrocytes respond robustly to TSH and thyroid-stimulating Igs by generating extremely high levels of inflammatory cytokines, such as IL-6...

BACKGROUND: Fibrocytes are implicated in Idiopathic Pulmonary Fibrosis (IPF) pathogenesis and increased proportions in the circulation are associated with poor prognosis. Upon tissue injury, fibrocytes migrate to the affected organ. In IPF patients, circulating fibrocytes are increased especially during exacerbations, however fibrocytes in the lungs have not been examined. Therefore, we sought to evaluate if fibrocytes can be detected in IPF lungs and we compare percentages and phenotypic characteristics of lung fibrocytes with circulating fibrocytes in IPF...

Both microRNA (miRNA) and long noncoding RNA (lncRNA) fall within the category of noncoding RNA. MiRNA is a 20-24 nt long, highly conserved, single-stranded noncoding RNA. MiRNA can specifically bind to the 3' untranslated region of target mRNA, induce the transcript degradation or translation inhibition, and eventually impact the biological functions of the cell, such as proliferation, differentiation, and apoptosis. Whereas lncRNA is an over 200 bp long, single-stranded, noncoding RNA, which can regulate the important biological processes, such as cell division, growth, differentiation and apoptosis...

Fibrosis is the common final pathway of virtually all chronic injury to the kidney. While it is well accepted that myofibroblasts are the scar-producing cells in the kidney, their cellular origin is still hotly debated. The relative contribution of proximal tubular epithelium and circulating cells, including mesenchymal stem cells, macrophages, and fibrocytes, to the myofibroblast pool remains highly controversial. Using inducible genetic fate tracing of proximal tubular epithelium, we confirm that the proximal tubule does not contribute to the myofibroblast pool...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a progressive disease with high mortality, and the pathogenesis of the disease is still incompletely understood. Although lymphocytes, especially CD4+ CD25+ FoxP3+ regulatory T cells (Tregs), have been implicated in the development of IPF, contradictory results have been reported regarding the contribution of Tregs to fibrosis both in animals and humans. The aim of this study was to investigate whether a specific T cell subset has therapeutic potential in inhibiting bleomycin (BLM)-induced murine pulmonary fibrosis...

AIM: To explore the expression profile of CD45+/pro-collagen I+ fibrocytes in intact dental pulps as well as during wound healing in adult dental pulp tissue. METHODOLOGY: A total of 16 healthy permanent teeth were obtained from young patients (18 to 25 years) undergoing orthodontic treatment. Routine pulp capping with mineral trioxide aggregate (MTA) was performed under local anaesthesia to induce a mineralized barrier at the exposed surface. Teeth were extracted from patients after 7, 14, and 35 days...

Fibrocytes are unique cells with innate and adaptive immune functions, but these mechanisms have not been fully explored. The aim of this study was to explain the mechanism by which adoptive transfer of exogenous fibrocytes improved bacterial clearance and increased sepsis survival. Initial flow cytometry-based, in vitro assays demonstrated phagocytosis by fibrocytes and intracellular bacterial killing was confirmed by direct plating of cell lysates after exposure to live bacteria. Intravenous adoptive transfer of fibrocytes at the time of cecal ligation and puncture (CLP) or two hours after CLP in mice increased survivability...

BACKGROUND: In atrial fibrillation (AF), a more extensively fibrotic left atrium (LA) provides a substrate for arrhythmias and increases risk of relapse following ablation. Fibrocytes are bone marrow-derived circulating mesenchymal progenitors that have been identified in the atrium of patients with AF who have valvular diseases. The present study investigates the associations between circulating fibrocytes and LA fibrosis or the prevalence of recurrence after ablation in patients with persistent AF...

The aim of this study was to determine whether bone marrow-derived fibrocytes migrate into the cornea after stromal scar-producing injury and differentiate into alpha-smooth muscle actin (αSMA) + myofibroblasts. Chimeric mice expressing green fluorescent protein (GFP) bone marrow cells had fibrosis (haze)-generating irregular phototherapeutic keratectomy (PTK). Multiplex immunohistochemistry (IHC) for GFP and fibrocyte markers (CD34, CD45, and vimentin) was used to detect fibrocyte infiltration into the corneal stroma and the development of GFP+ αSMA+ myofibroblasts...

Cervical sarcomas are rare neoplasms, accounting for <1% of all cervical malignancies and characterized by an aggressive course despite radical excision. We report the clinical and microscopic features of a spindle cell sarcoma arising as a polypoid endocervical mass in a 45-yr-old woman. The neoplasm was characterized by a monotonous, mildly atypical proliferation of spindle cells, displaying a fibrosarcoma-like parallel pattern of highly dense fascicles, growing under the cervical epithelium. Mitotic activity was conspicuous, with up to 40 mitoses per 10 HPF...

A new cell type, interstitial Cajal-like cell (ICLC), was recently described in different organs. The name was recently changed to telocytes (TCs), and their typical thin, long processes have been named telopodes (Tp). TCs regulate the contractile activity of smooth muscle cells and play a role in regulating vessel contractions. Although the placenta is not an innervated organ, we believe that TCs are present in the placenta. We studied placenta samples from physiological pregnancies and in different variants of preeclampsia (PE)...

Idiopathic pulmonary fibrosis (IPF) is a chronic fibrotic lung disease that is prevalent in individuals >50 years of age, with a median survival of 3-5 years and limited therapeutic options. The disease is characterized by collagen deposition and remodeling of the lung parenchyma in a process that is thought to be driven by collagen-expressing immune and structural cells. The G-protein coupled C-X-C chemokine receptor 4, CXCR4, is a candidate therapeutic target for IPF owing to its role in the recruitment of CXCR4+ fibrocytes from the bone marrow to fibrotic lung tissue and its increased expression levels by structural cells in fibrotic lung tissue...

Cancer stem cells (CSCs) represent a minor population that have clonal tumor initiation and self-renewal capacity and are responsible for tumor initiation, metastasis, and therapeutic resistance. CSCs reside in niches, which are composed of diverse types of stromal cells and extracellular matrix components. These stromal cells regulate CSC-like properties by providing secreted factors or by physical contact. Fibrocytes are differentiated from bone marrow-derived CD14+ monocytes and have features of both macrophages and fibroblasts...

In the field of neurosurgery, often the dura mater cannot be sutured, and consequently, it requires a duraplasty procedure using a dural fascial graft. Since 1890, various materials have been researched as dura mater substitutes. Amniotic membrane, for example, is suitable as a dural graft material and has been used in neurosurgery since 2012. However, there has been little research on human patient's dural healing after the use of amniotic membrane in their duraplasty procedure. To address this gap, a clinical experimental study was undertaken to evaluate the human dural healing of 16 patients who had undergone duraplasty in decompressive craniectomy surgery at Dr...

Background: Giant cell tumor (GCT) of the bone is known for its locally aggressive behavior and tendency to recur. It is an admixture of rounded or spindle-shaped mononuclear neoplastic stromal cells and multinucleated osteoclast-like giant cells with their proportionate dispersion among the former. Zoledronic acid (a bisphosphonate) is being used in various cancers such as myelomas and metastasis, for osteoporosis with an aim to reduce the resorption of bone, and as an adjuvant treatment for the management of GCT of bone for reduction of local recurrence...
