Purpose: This study was carried out to isolate mesenchymal stem cells from full-term cord blood and to differentiate these cells into osteoblastic cells. Materials and Methods: It this study, mesenchymal stem cells were isolated from cord blood and expanded by being cultured in the flask several times. First, the cord blood monoeuc1earcells were separated by ficoll - Hypac before they were cul...
There are two main categories for stem cells a cording to their origin: Embryonic Stem Cells and Adult Stem Cell. Mesenchymal stem cell, supporting hematopoetic stem cells in bone marrow, can regenerate tissues such as bone, cartilage, muscle, tendon and fatty tissue. These cells were recognized for the first time by Friedenstein and Petrokova who could isolate theme from rat bone marrow.Mesenc...
Background: The application of mesenchymal stem cells in the healing of chronic wounds is one of the most challenging issues in cell therapy. The present study investigated the efficacy of intradermal injection of umbilical cord Wharton's Jelly-derived mesenchymal stem cells in diabetic wound healing using ultrasound imaging in an animal model. Methods: During this experimental laboratory stud...
Introduction: One of the vital enzymes during spermatogenesis, which is one of the pluripotency factors of stem cells and contributes to maintaining their pluripotency is alkaline phosphatase. ZBTB16 and ZFP proteins are critical elements in stem cells which are expressed in pluripotent stem cells and maintain their pluripotency due to their role in messaging pathways. Material & Methods: The ...
background: limited resources for adult stem cells necessitate their in vitro culture prior to clinical use. investigating mitochondrial dna (mtdna) and telomere shortening has proved to be important indications of stem cell validity. this study was designed to investigate these indicators in multiple passages of three adult stem cell lines which were produced in our stem cell laboratory. metho...
s:3604:"During pregnancy, the placenta delivers "cord blood" to the baby through the umbilical cord serving as a lifeline of nourishment from the mother to baby. At birth, "cord blood" remains in the umbilical cord and placenta and until recently, had typically been discarded. The tragedy of this practice is that "cord blood" contains very special cells called "stem cells". Recent advances in m...
Introduction: Aging is a natural phenomenon that is caused by changes in the cells of the body. Theoretically, aging starts from birth and lasts throughout life. These changes affect the function of the cells. Also, in old tissues, the capacity for homeostasis and tissue repair is decline due to destructive changes in specific tissue stem cells, niche of stem cells and systemic factors that reg...
Primary and secondary malignant central nervous system (CNS) tumors are devastating invasive tumors able to give rise to many kinds of differentiated tumor cells. Glioblastoma multiform (GBM), is the most malignant brain tumor, in which its growth and persistence depend on cancer stem cells with enhanced DNA damage repair program that also induces recurrence and resists current chemo- and radi...
background wisdom teeth are usually removed as a routine procedure for therapeutic or prophylactic reasons. developing wisdom teeth are easy accessible source of stem cells during the adulthood which could be obtained. methods search of the pubmed for stem cells and tooth was done. an inclusion criterion was extract of stem cells from wisdom tooth. results stem cells can be obtained from den...
Background: Recent publications regarding the differentiation of stem cells to germ cells have motivated researchers to make new approaches in infertility. In vitro production of germ cells improves the understanding of differentiation process of male and female germ cells. Since using embryonic stem cells for this purpose has been associated with tumorogenesis and ethical criticisms, the men...
