1. Goat umbilical cord cells are permissive to small ruminant lentivirus infection in vitro
Abstract Small ruminant lentiviruses isolated from peripheral blood leukocytes and target organs can be propagated in vitro in fibroblasts derived from goat synovial membrane cells. These cells are obtained from tissues collected from embryos or fetuses and are necessary for the establishment of the fibroblast primary culture. A new alternative type of host

2. Human mesenchymal stem cells are resistant to cytotoxic and genotoxic effects of cisplatin in vitro
Abstract Mesenchymal stem cells (MSCs) are known for their important properties involving multilineage differentiation potential., trophic factor secretion and localization along various organs and tissues. On the dark side, MSCs play a distinguished role in tumor microenvironments by differentiating into tumor-associated fibroblasts or supporting tumor grow

3. Rabbit olfactory stem cells. Isolation protocol and characterization
PURPOSE: To describe a new technique for isolation of a mesenchymal stem cells (MSCs) population from the olfactory mucosa in rabbits. METHODS: Olfactory stem cells (OSCs) were retrieved from under the cribriform plate of the Ethmoid bone. Several assays were accomplished to characterize the cell population and attest its viability in vitro. The cells were

4. Immunological characteristics of mesenchymal stem cells
Although bone marrow is the main source, mesenchymal stem cells have already been isolated from various other tissues, such as the liver, pancreas, adipose tissue, peripheral blood and dental pulp. These plastic adherent cells are morphologically similar to fibroblasts and have a high proliferative potential. This special group of cells possesses two essenti

5. Avaliação da indiferenciação celular e indução de neurodiferenciação em co-cultivo de fibroblastos NIH 3T3 com células mononucleares do sangue de cordão umbilical
Cellular therapy represent a new frontier for the treatment of several diseases, including diseases related to central nervous system. Human umbilical cord blood is an attractive source of stem cells; however, it has a heterogeneous population with a small amount of mesenchymal stem cells. Currently, cell reprogramming induced by different methodologies can

6. Functional study of mesenchymal cells with pathogenic mutations in TCOF1 / Estudo funcional de células mesenquimais com mutações patogênicas no TCOF1
Neste trabalho tentamos traçar quais seriam os efeitos funcionais e de expressão gênica de mutações patogênicas no gene TCOF1 em células não embrionárias. A partir do estabelecimento de culturas celulares oriundas de periósteo facial de quatro pacientes portadores da síndrome de Treacher Collins (STC), obtivemos populações celulares com mais de

7. Human Umbilical Cord Mesenchymal Stem Cells Reduce Fibrosis of Bleomycin-Induced Lung Injury
Acute respiratory distress syndrome is characterized by loss of lung tissue as a result of inflammation and fibrosis. Augmenting tissue repair by the use of mesenchymal stem cells may be an important advance in treating this condition. We evaluated the role of term human umbilical cord cells derived from Wharton’s jelly with a phenotype consistent with mes

8. Fibroblast biology: Signals targeting the synovial fibroblast in arthritis
Fibroblast-like cells in the synovial lining (type B lining cells), stroma and pannus tissue are targeted by many signals, such as the following: ligands binding to cell surface receptors; lipid soluble, small molecular weight mediators (eg nitric oxide [NO], prostaglandins, carbon monoxide); extracellular matrix (ECM)-cell interactions; and direct cell-cell

9. Mesenchymal stem cells produce Wnt isoforms and TGF-β1 that mediate proliferation and procollagen expression by lung fibroblasts
Studies have been carried out previously to determine whether mesenchymal stem cells (MSC) influence the progression of pulmonary fibrosis. Here, we asked whether MSC (derived from mouse bone marrow and human umbilical cord blood) produce factors that mediate lung fibroblast (LF) growth and matrix production. MSC-conditioned media (CM) were found by ELISA to

10. Cartilage homeoprotein 1, a homeoprotein selectively expressed in chondrocytes.
We identified a rat cDNA that encodes cartilage homeoprotein 1 (Cart-1). The deduced amino acid sequence of Cart-1 contains a paired-type homeodomain. Northern blot hybridization and RNase protection assay revealed that Cart-1 RNA was present at high levels in a well-differentiated rat chondrosarcoma tumor and in a cell line derived from this tumor. Cart-1 R

11. Azacytidine-induced tumorigenesis of CHEF/18 cells: correlated DNA methylation and chromosome changes.
5-Azacytidine (azaC), a drug that induces decreased methylation of DNA in mammalian cells, was shown previously to induce differentiation of mesenchymal cell types in CHEF/18 cells (Chinese hamster embryo fibroblasts). This paper describes the effectiveness of azaC in inducing tumorigenicity in CHEF/18 cells, previously shown to be nontumorigenic stable dipl

12. Induction of peroxisome proliferator-activated receptor gamma during the conversion of 3T3 fibroblasts into adipocytes is mediated by C/EBPbeta, C/EBPdelta, and glucocorticoids.
The differentiation of 3T3 preadipocytes into adipocytes is accompanied by a transient induction of C/EBPbeta and C/EBPdelta expression in response to treatment of the cells with methylisobutylxanthine (MIX) and dexamethasone (DEX), respectively. In this report, we demonstrate that peroxisome proliferator-activated receptor gamma (PPARgamma) expression in 3T
