Abstract Background Previous studies demonstrated the dependence of cancer on nerve. Recently, a growing number reveal that cells share property and regulatory network with neural stem/progenitor cells. However, relationship between stemness cell tumorigenicity is unknown. Results We show cells, but not non-neural embryonic or somatic types, exhibit potential for differentiation into tissue typ...
Objective(s): Hyperglycemia, oxidative stress and apoptosis have key roles in pathogenesis of diabetic neuropathy. There are local renin-angiotensin systems (RASs) in different tissues such as neural tissue. Local RASs are involved in physiological and pathophysiological processes such as inflammation, proliferation and apoptosis. This study aimed to investigate the role of local renin-angioten...
introduction: the aim of this study was evaluate the ability of notochord to induce neural induction and/or differentiation of mouse embryonic stem cell to neuron and motor neuron, respectively. methods: in order to produce embryoid bodies, es cells line royan b1 were grown in suspension in the absence of lif for 4 days. ebs were divided into 4 groups. ebs in group 1 & 2 were further cultured i...
Previous analyses of single neural crest cell trajectories have suggested important roles for interactions between neural crest cells and the environment, and amongst neural crest cells. To test the relative contribution of intrinsic versus extrinsic information in guiding cells to their appropriate sites, we ablated subpopulations of premigratory chick hindbrain neural crest and followed the r...
Traumatic brain injury (TBI) leading to 5 million deaths annually is 1 of the 5 major causes of morbidity and mortality worldwide. In Iran, accidents are the main cause of death in youth as well as a dominant factor in reducing quality of life. In developing countries TBI incidence as one of the worst consequences of these accidents is growing due to wide use of motor-vehicles. Therapeutic stra...
Background: Neurofollicular hamartoma (NFH) is characterized histopathologically by fascicles of spindle cells that laterally delimited by hyperplastic folliculosebaceous units. It usually appears on face, near the nose or nasolabial fold. It does not manifest true neural differentiation and recently the term spindle cell predominant trichodiscoma (SCPT) has been used instead. Case Presentatio...

The neural crest is a unique population of mitotically active, multipotent progenitors that arise at the vertebrate neural plate border. Here, we show that the helix-loop-helix transcriptional regulator Id3 has a novel role in cell cycle progression and survival of neural crest progenitors in Xenopus. Id3 is localized at the neural plate border during gastrulation and neurulation, overlapping t...
