Bone morphogenetic protein (BMP)-4 has a crucial role on primordial germ cells (PGCs) development in vivo which can promote stem cell differentiation to PG-like cells. In this study, we investigated the expression of Mvh as one of the specific genes in primordial germ cells after treatment with different doses of BMP4 on bone mesenchymal stem cells(More)
BACKGROUND/AIMS Several lines of evidence point to the role of neurobiological mechanisms and genetic background in bipolar disorder (BD). The interleukin-1 receptor antagonist (IL-1Ra) is the principal regulator of IL-1α and IL-1β bioactivities. This study aimed to investigate the potential role of the variable number of tandem repeats (VNTR) polymorphisms(More)
Extracellular matrix (ECM) could influence cells function through providing structural and functional networks facilitating the cellular interactions. The present study was conducted to evaluate the effect of culture on ECM versus plastic on bovine spermatogonial stem cells (SSCs) and growth factors regulating their development. Following isolation, bovine(More)
BACKGROUND Mesenchymal Stem Cells (MSCs) are multipotent cells that can be collected from different sources. Under specific conditions, MSCs can be differentiated to tissue specific cells in vitro. Human Umbilical Cord mesenchymal Stem Cells (hUCMSCs) can easily be harvested and cultured in in vitro conditions. Production of germ cells from mesenchymal stem(More)
Research about potential use of stem cells for the development of germ line cells in vitro had been challenged. In the present study, we reported a novel protocol consisting of cocktail growth factor addition for germ cell differentiation followed by transfection. The cells were purificated based on the expression on the cell surface of a protein. This(More)
OBJECTIVE Lack of appropriate approaches that reliably predict response of Wilms' tumor (WT) to anticancer agents remains a major deficiency in clinical practice of individualized cancer therapy. The aim of this study was to establish a patient-derived tumor tissue (PDTT) xenograft model of WT for individualized chemotherapeutic regimen selection in(More)
BACKGROUND Follicular fluid (FF) is biological fluid rich in nutrients, growth factors, hormones and may affect the sperm quality. Sperm washing has been done using conventional media in laboratory procedure so far. AIM This study aimed to investigate the effects of FF on survival and maintenance of chromatin integrity post swim up. MATERIALS AND(More)
OBJECTIVES Mesenchymal stem cells (MSCs) derived from Wharton's jelly (WJ-MSCs) are now much more appealing for cell-based infertility therapy. Hence, WJ-MSCs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. MATERIALS AND METHODS MSCs were isolated from human Wharton's jelly and treated with BMP4,(More)
Human umbilical Wharton’s jelly-derived mesenchymal stem cells (HWJMSCs) are the best candidate to get plentiful stem cells and differentiate them to germ cells under appropriate conditions to treat infertility. We sought to determine under which conditions HWJMSCs could form male germ cells in vitro. So, HWJMSCs were differentiated to male germ cells under(More)
OBJECTIVES Increased levels of nitric oxide (NO) in the testicular veins of people suffering from varicocele have already been reported. However, the role of NO-synthase (NOS) isozymes and their inhibitors have not been extensively studied. We aimed to evaluate the inhibitory effects of aminoguanidine (AG), on sperm motility, vitality, and mitochondrial(More)
