چکیده

Although the mammalian germinal stem cell (GSC) provides a good model to investigate the regulation of stem cells, the small number of these cells currently available hampers elucidation of the regulatory mechanism. Here, we show the dramatic amplification of GSCs in mouse testis following transfection of human glial cell line-derived neurotrophic factor cDNA into Sertoli cells using an efficient, in vivo electroporation technique. Transplantation analysis demonstrated not only GSC enrichment but also differentiation from stem cells into sperm. The GSC population, as estimated using a colony-formation assay, was approximately 20-fold greater than in cryptorchid testis, or approximately 500- to 1000-fold greater than in normal adult testis. This system should provide sufficient quantities of GSCs to accelerate our understanding of GSC properties, regulation mechanisms, and behavior control.

The Effects of Progesterone on Glial Cell Line-derived Neurotrophic Factor Secretion from C6 Glioma Cells

Objective(s)Progesterone is a steroid hormone whose biology has been greatly studied within the confines of reproductive function. In recent years, the neuroprotective effects of progesterone have attracted growing interest. Glial cell line-derived neurotrophic factor (GDNF), is a neurotrophic factor which plays a crucial role in the development and maintenance of distinct sets of central and p...

Human Olfactory Ecto-mesenchymal Stem Cells Displaying Schwann-Cell-Like Phenotypes and Promoting Neurite Outgrowth in Vitro

Strategies of Schwann cell (SC) transplantation to regenerate the peripheral nerve injury involves many limitations. Stem cells can be used as alternative cell sources for differentiation into SCs. Given the high potential of neural crest-derived stem cells for the generation of multiple cell lineages, in this research, we considered whether olfactory ecto-mesenchymal stem cells (OE-MSCs) derive...

P 89: Reduction of Neuroinflammation in Epilepsy by Using Stem Cells Derived Astrocytes

Epilepsy is neurological disorders that afflict many people around the world with a higher prevalence rate in children and in low income countries. Temporal lobe epilepsy (TLE) is result from hippocampal sclerosis is a neurological disorder with difficult treatment. Stem cells can transform into any type of cells such as glial cells, consequently stem cells can use for medical treatment. Stem c...

Extract of mouse embryonic stem cells induces the expression of pluripotency genes in human adipose tissue-derived stem cells

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...
