Background and Aims: In the last decade, several studies have reported the isolation of stem cell population from different dental sources, while their mesenchymal nature is still controversial. The aim of this study was to introduce the isolating methods for stem cells from human dental pulp and to determine their mesenchymal nature before differentiation. Material and methods: One of the ...
Traumatic brain injury is considered as one of the main causes of morbidity and mortality worldwide. Apart from primary mechanical injury, Secondary injuries due to inflammation and apoptosis result in great neuronal damage. Current treatments are not able to regenerate the damaged part and prevent future sequels. Using human stem cells with self-assembling scaffolds may be promising in treatme...
Introduction: Brain injury is an important cause of morbidity and mortality worldwide and so far, there has been no absolute treatment for the damaged brain tissue. Using human stem cells with self-assembling scaffolds can be a promising method for treatment of traumatic brain injury. Materials and Methods: Human meningioma stem cells were isolated, cultured and then expanded into in vitro cond...
objective adult stem cells which are derived from different tissues, with their unique abilities to self-renew and differentiate into various phenotypes have the potential for cell therapy and tissue engineering. human adipose tissue is an appropriate source of mesenchymal stem cells with wide differentiation potential for tissue engineering research. in this study isolated stem cells from huma...
new blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ecs) which in turn give rise to primitive capillary network. human cord blood (hcb) contains large subsets of mononuclear cells (mncs) that can be differentiated into endothelial-like cells in vitro. human mononuclear progenitor cells were purified from fresh umb...
background: objective: this study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis materials and methods: isolated testicular cells were cultured in dmem/f12. characteristics of the isolated cells and obtained es-like cell were immune-cytochemically confirmed by examining the presence of plzf, vimentin, oct4 and nanog prote...
Spermatogenesis is a highly complex and regulated process in which germ stem cells differentiate into spermatozoa. These stem cells, called spermatogonial stem cells (SSCs), are in the base of seminiferous tubules and have the ability of self-renewal and differentiation into functional germ cells. Due to this ability, SSCs can restore spermatogenesis after testicular damage caused by cytotoxic ...
Background and Objective: Nowadays, although umbilical cord blood is a commonly used source of hematopoietic stem cell, its low frequency of these cells is the main factor limiting its clinical application. The transplantation of hematopoietic stem cells derived from placenta tissue along with umbilical cord blood cells of the same sample may be an appropriate approach to solve this problem. In...
Stem cells are one of the most challenging areas of patent law as one of the important medical resources for the treatment of various diseases. The scope of this challenge relying on the legal approaches of countries depends on how to satisfy substantive requirments and moral considerations, especially in the field of embryonic stem cells. Accordingly, although such cells could be considered pa...
Parkinson’s disease (PD) is a progressive neurodegenerative disease characterized by motor and non-motor symptoms. It is expected to impose an increasing economic and social burden on human populations. The motor symptoms of PD are well known, including age-dependent uncontrollable resting tremor, bradykinesia, rigidity, posture instability. In the non-motor symptoms, cognitive changes, d...
