Traumatic brain injury (TBI) is a disruption in the brain functions following a head trauma. Cell therapy may provide a promising treatment for TBI. Human neural stem cells cultured in self-assembling peptide scaffolds have been proposed as a potential novel method for cell replacement treatment after TBI. In the present study, we accessed the effects of human neural stem/progenitor cells (hNS/...

objective: there is longstanding experimental and clinical evidence that supports the idea that replacement of dopaminergic (daergic) neurons can ameliorate functional disabilities of parkinson’s disease (pd). the purpose of the present study is to examine the efficacy of transplantation of rat bone marrow stromal cell (bmscs)-derived tyrosine hydroxylase-positive (th+) cells induced by depreny...

Lateral labial melanocytic nevus or mole has cosmetic value among young or middle aged Iranian ladies particularly those with fair complexion. I describe auto transplantation of a melanocytic nevus from a remote area of the body to lateral labial skin. After selection of a 3-mm nevus, both donor and recipient sites were anesthetized. A punch with a diameter comparable to the diameter of t...

BACKGROUND Islet transplantation is a successful β-cell replacement therapy for selected patients with type 1 diabetes mellitus. Although high rates of early insulin independence are achieved routinely, long-term function wanes over time. Intraportal transplantation is associated with procedural risks, requires multiple donors, and does not afford routine biopsy. Stem cell technologies may requ...

the pathology of spinal cord injury (sci) comprises multiple processes characterized by extensive cell death and glial scar formation, which together limits axonal regeneration. in particular, variations in chronic demyelination of the lesion have been found to be largely independent of injury intensity, suggesting a secondary pathologic origin. this chronic demyelination results in progressive...
