The aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. Blastocyst stage embryos from pregnant NMRI mice were obtained and cultured for 1-2 days in DMEM medium. The inner cell masses formed...
Objective(s): In the past few decades, variety of foetal, embryonic and adult stem and progenitor cells have been tried with conflicting outcome for cell therapy of central nervous system injury and diseases. Cellular characteristics and functional plasticity of Globose basal stem cells (GBCs) residing in the olfactory epithelium of rat olfactory mucosa have not been studied in the past by the ...
Background and Aim: Embryonic stem cells are identified with two unique characteristics. First, they can be maintained and expanded as pure populations of undifferentiated cells, a characteristic which is known as self renewal aspect of embryonic stem cells. Second, these cells can give rise to all body cell types. In the current study, we used a feeder-free condition to differentiate mouse emb...
Background: The main objective of this study was to systematically review the reported potency of cord blood stem cells in treating patients with neurological disorders such as cerebral palsy. Methods: PubMed, Scopus, and Cochrane were searched thoroughly on September 2016 using the following search terms: “Umbilical cord blood stem cells” AND “development” AND “cerebral palsy” to find articl...
Introduction: Parkinson disease (PD) results from the destruction of dopaminergic neurons in the brain. This study aimed to investigate the protective effects of natural antioxidants such as caffeic acid phenethyl ester (CAPE) to maintain these neurons. Methods: CAPE is one of the main ingredients of propolis. Intranasal administration of 1-methyl-4-phenyl-2;3;4;6-tetrahydropyridine (MPTP) was...
Hair loss is a common hair disorder in human population. It affects quality of life and there are ongoing attempts to find permanent treatment for this condition. But, today there is no completely safe and protective treatment for all. Hair follicle stem cells are alive, but quiescence in androgenetic alopecia and are potentially active and can proliferate and differentiate, then regenerate hai...
context stem cells have the potential to generate a renewable source of cells for regenerative medicine due to their ability to self-renew and differentiate to various functional cell types of the adult organism. the extracellular microenvironment plays a pivotal role in controlling stem cell fate responses. therefore, identification of appropriate environmental stimuli that supports cellular p...
The brain is an important organ that controls all sensory and motor actions, memory, and emotions. Each anatomical and physiological modulation in various brain centers, results in psychological, behavioral, and sensory-motor changes. Alcohol and addictive drugs such as opioids and amphetamines have been shown to exert a great impact on brain, specifically on the hippocampus. Emerging evidence ...
Introduction: Cardiovascular diseases (CVD) are the primary cause of death worldwide, and the development of scar tissue in myocardium and also the irreversible destruction of cardiomyocytes are the main factors in their development. There are still limitations in medical treatment of CVD, despite the advances in the field of drug therapy and surgery for CVD. In recent years, research on stem c...
Emergence and spread of various diseases in the past century have been associated with many problems for the health care providers. Now a days, with advancement of technology, new methods such as cell therapy, are available, efficient and successful in some clinical areas. To use any cell, it is necessary to identify its source, so herein, we reviewed the literature of a new source of adult ste...
