Background and Objective: The resin secretions of Cannabis sativa are called Hashish, which has medicinal and psychological properties. The most important psychoactive compound of this plant is THC (Delta-9-Tetrahydrocannabinol), which can stimulate cannabinoid receptors in the body. This study was carried out to evaluate the effect of hydroalcoholic extract of Cannabis sativa on cell survival ...
The activation of the WNT signaling pathway is a Hallmark in neurofibromatosis type 1 tumorigenesis.
PURPOSE The hallmark of neurofibromatosis type 1 (NF1) is the onset of dermal or plexiform neurofibromas, mainly composed of Schwann cells. Plexiform neurofibromas can transform into malignant peripheral nerve sheath tumors (MPNST) that are resistant to therapies. EXPERIMENTAL DESIGN The aim of this study was to identify an additional pathway in the NF1 tumorigenesis. We focused our work on W...
Stem cells are undifferentiated biological cells that can differentiate into more specialized cells and divide (through mitosis) to produce more stem cells (self-renew). In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. Mesenchymal stem cells (MSCs) are ...
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 huma...
Human mesenchymal stem cells (hMSCs), which also called mesenchymal stromal cells, are multipotent stem cell. Human MSCs typically are positive for the surface markers CD44, CD73, CD90, CD105, CD106, and also negative for hematopoietic markers CD34 and CD45.These cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...
Abstract Background and Aim: In recent years, Mesenchymal stem cell functions have been at the center of attention of researchers. Evidence shows that Mesenchymal stem cells act as paracrine manner and thus, biological agents such as exosomes and soluble factors are present in the supernatant that can act as same as Mesenchymal stem cells. Therefore, isolating exosomes from mesenchymal stem ce...
understanding the molecular mechanisms in regeneration could help the stem cell therapists to improve the clinical practices and could be considered a major milestone in the translation of stem cell research to clinics. chemokines have been described as one of the most significant singling networks in stem cells homing and regeneration of damaged organs. cxcr4/cxcl12 has been known as a key pla...
background: in this study, we examined a new two step induction protocol for improving the differentiation of human umbilical cord blood-derived mesenchymal stem cells into neural progenitor cells. materials and methods: human umbilical cord blood-derived mesenchymal stem cells were first cultured in dulbecco’s modified eagle medium supplemented with 10% fetal bovine serum in a humidified incub...
Introduction: Vitamin E as a strong antioxidant plays an important role in inhibiting free radicals. Therefore, this study aimed to investigate the effect of vitamin E on the viability, morphology and osteogenic differentiation in bone marrow mesenchymal stem cells of an adult rat. Methods: The bone marrow mesenchymal stem cells were extracted using the flashing-out method. At the end of the t...
Abstract Background: Adipose tissue is being used word-wide as a suitable adult stem cell source the aim of this study was to examine the possibility of using different enzymes to isolate the human mesenchymal stem cells from adipose tissue. Methods: Adipose tissues which were obtained from liposuction surgery were transferred to the laboratory under sterile conditions. All samples obtained...
