background: the failure of regeneration after spinal cord injury (sci) has been attributed to axonal demyelination and neuronal death. cellular replacement and white matter regeneration are both necessary for sci repair. in this study, we evaluated the co-transplantation of olfactory ensheathing cells (oec) and embryonic stem (es) cell-derived motor neurons (esmn) on contused sci. methods: oec ...

bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. recently, various stem cells, including embryonic stem cells (escs), bone marrow-derived mesenchymal stem cells (bm-mscs), umbilical cord blood-derived mesenchymal stem cells (ucb-mscs), adipose tissue-derived stem cells (adscs), muscle-derived stem cell...

introduction: type i diabetes mellitus is caused by autoimmune destruction of the insulin-producing β-cells. a new potential method for curing the disease is transplantation of differentiated insulin- secreting cells from human embryonic stem cells. methods: human embryonic stem cell lines (royan h1) were used to produce embryoid bodies. differentiation carried out by growth factor-mediated sel...

stem cell therapy can be useful for spinal cord injury (sci). induced pluripotent stem cells (ipscs) are generated by reprogramming mature, fully differentiated cells into a pluripotent state. the ability to generate pluripotent cells from adult somatic cells without the need for an embryo was a major development in stem cell biology. ipscs were established from mouse fibroblasts and demonstrat...

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...

The human embryonic stem cell line, KthES11, is derived from a normal healthy blastocyst donated for clinical research. inner mass (ICM) was isolated using mechanical dissection and plated on laminin fragments. Cell line derivation, its propagation storage were performed without feeders in an animal product-free environment according to current Good Manufacturing Practice (cGMP) standards. KthE...

The pig is important for agriculture and as an animal model in human and veterinary medicine, yet despite over 20 years of effort, there has been a failure to generate pluripotent stem cells analogous to those derived from mouse embryos. Here we report the production of leukemia inhibitory factor-dependent, so-called naive type, pluripotent stem cells from the inner cell mass of porcine blastoc...

Human embryonic stem (ES) cells are undifferentiated pluripotent cells derived from the inner cell mass of blastocyst stage embryos. These unique cell lines have the potential to form virtually any cell type in the body and can be propagated in vitro indefinitely in an undifferentiated state. These cells are capable of forming embryoid bodies (EB) that contain cells from all three embryonic lin...

Objective(s): In some previous studies, the extract of embryonic carcinoma cells (ECCs) and embryonic stem cells (ESCs) have been used to reprogram somatic cells to more dedifferentiated state. The aim of this study was to investigate the effect of mouse ESCs extract on the expression of some pluripotency markers in human adipose tissue-derived stem cells (ADSCs). Materials and Methods: Human A...
