Recent advances in trans-differentiation of one type cell to another have made it possible to directly convert Huntington's disease (HD) patient fibroblasts into neurons by modulation of cell-lineage-specific transcription factors or RNA processing. However, this possibility has not been examined. Here, we demonstrate that HD patient-derived fibroblasts can be directly trans-differentiated into...

About thirty years ago, the interlukin-6 (IL-6) which is the proinflammatory cytokine, was detected as the differentiation factor of B cell. IL-6 is able to induce maturation in B cells and as a result, B cells achieve the ability to produce antibodies. In addition to immune responses, the role of IL-6 has been known in neurogenesis (neurons and glial cells). The studies have showed that the ab...

background: some antidepressant drugs can promote neuronal cell proliferation in vitro as well as hippocampal neurogenesis in human and animal models. furthermore, adipose tissue is an available source of adult stem cells with the ability to differentiate in to multiple lineages. therefore, human adipose-derived stem cells (hadscs) may be a suitable source for regenerative medical applications....

Small cell lung carcinomas (SCLCs) represent highly aggressive tumors with an overall five-year survival rate in the range of 5 to 10%. Here, we show that four out of five SCLC cell lines reversibly develop a neuron-like phenotype on extracellular matrix constituents such as fibronectin, laminin or thrombospondin upon staurosporine treatment in an RGD/integrin-mediated manner. Neurite-like proc...

The neuron cell bodies and glia cells are separated by a narrow intercellular cleft of 200 A. We present here evidence that perikarya neuronal and perineuronal glia of the superior colliculus of the Oryctolagus Cuniculus communicate through gap-like junctions according to ultrastructural parameters. These junctions would mean some degree of electronic coupling between neuron cell bodies and per...

The present study evaluated the ability and optimal concentration of tetramethylpyrazine (TMP) to induce human umbilical cord-derived mesenchymal stem cells (hUMSCs) to differentiate into neuron‑like cells in vitro. Human umbilical cords from full-term caesarean section patients were used to obtain hUMSCs by collagenase digestion after removal of the umbilical artery and vein. The surface antig...

Spermatogonial stem cells (SSCs) renew themselves throughout the life of an organism and also differentiate into sperm in the adult. They are multipopent and therefore, can be induced to differentiate into many cells types in vitro. SSCs from pigs, considered an ideal animal model, are used in studies of male infertility, regenerative medicine, and preparation of transgenic animals. Here, we re...
