Introduction Based on previous researches, dental pulp stem cells (DPSCs) are easily accessible with limited morbidity after collection. Their embryonic origin, from neural crests, explains their multipotency. DPSCs are primarily derived from the pulp tissues of the teeth.Objective: This study was undertaken to isolate, culture, and characterize two different third molar and first premolar hum...

Imbalance in immune responses plays an indispensable role pathogenesis and development of multiple sclerosis (MS), as a neurodegenerative disorder. Current treatments are not always successful preventing MS treating the disease. Stem cell-based cell therapy has provided new window for disorders. cells can regulate system improve axonal remyelination. They be isolated from different origins such...

background dox is a powerful chemotherapeutic agent used in the treatment of solid tumors and malignant hematological diseases. however, its cardiac toxicity limits the clinical usefulness of this drug. previous reports have shown corticosteroids induce a cytoprotective effect on cardiomyocytes. mouse transgenic embryonic stem cell-derived pure cardiomyocytes may be considered as a model for as...

The embryonic brain is radiation-sensitive, with cognitive deficits being observed after exposure to low radiation doses. Exposure of neonates to radiation can cause intracranial carcinogenesis. To gain insight into the basis underlying these outcomes, we examined the response of the embryonic, neonatal and adult brain to low-dose radiation, focusing on the neural stem cell compartments. This r...

We have generated a murine embryonic stem cell line constitutively expressing L1 at all stages of neural differentiation to investigate the effects of L1 overexpression on stem cell proliferation, migration, differentiation, cell death, and ability to influence drug-induced rotation behavior in an animal model of Huntington's disease. L1-transfected cells showed decreased cell proliferation in ...

It has been proposed that human embryonic stem cells could be used to provide an inexhaustible supply of differentiated cell types for the study of disease processes. Although methods for differentiating embryonic stem cells into specific cell types have become increasingly sophisticated, the utility of the resulting cells for modeling disease has not been determined. We have asked whether spec...

abstract spinal cord injury (sci) is a devastating condition producing great personal and societal costs and for which there is no effective treatment. stem cell transplantation is a promising therapeutic strategy, though much preclinical and clinical research work remains. here, we briefly describe sci epidemiology, pathophysiology, and transplantation trial in human developments, including te...

Most organs rely on stem cells to maintain homeostasis during post-embryonic life. Typically, stem cells of independent lineages work coordinately within mature organs to ensure proper ratios of cell types. Little is known, however, on how these different stem cells locate to forming organs during development. Here we show that neuromasts of the posterior lateral line in medaka are composed of ...
