stem cell research has obtained much prominence in recent years for its therapeutic potential in dealing with serious diseases, many of which are essentially incurable by routine therapies. mesenchymal stem cells with pluripotency and immunomodulatory properties are suitable candidates for tissue engineering and regenerative medicine. today, nanofibrous scaffolds are widely used in tissue engin...

Introduction: Contrary to a common belief, most mammalian females lose the ability of Germ Cell (GC) renewal and oogenesis during fetal life. Although, it has been claimed that germ line stem cells preserve oogenesis in postnatal mouse ovaries, that postnatal oogenesis keeps producing functional and sufficient GCs in the case of infertility (caused by different reasons) is doubtful. On the othe...

mesenchymal stem cells can be obtained from deferent tissues like adipose tissue, umbilical cord, placenta, skin, bone marrow, etc. these cells have regulatory effects on all types of immune cells such as dendritic cell, natural killers and lymphocytes. mesenchymal stem cells induce inhibitory phenotypes of antigen presenting cells (apcs) following their activity. they also change t cells pheno...

background: mesenchymal stem cells (mscs) are undifferentiated cells that can differentiate and divide to other cell types. transplantation of these cells to the different organs is used for curing various diseases. objective: the aim of this research was whether mscs transplantation could treat the sterile testes. materials and methods: in this experimental study, donor mscs were isolated from...

Background: One of the key questions in biochemistry is why cell becomes aged and what are the involved factors? Why cell growth is stopped after some divisions and cells become senescent? This occurs in a greater frame in the whole body and cells dye after a while. Androgenetic alopecia (AGA) is characterized by a loss or decrease in hair follicle size, which could be related to the loss of ha...

the identification of multipotential mesenchymal stem cells (mscs) derived from adult human tissues such as bone marrow and connective tissues has provided exciting prospects for cell-based tissue engineering and regeneration. this review article focuses on the biology of mscs, their differentiation potentials in vitro and in vivo, and their application in tissue engineering. our current unders...

In contrast to mouse germ cell-derived pluripotent stem cells, the pluripotent state of human testis-derived embryonic stem cell (ESC)-like that spontaneously arise in primary testicular cell cultures remains controversial. Recent studies have shown that these cells closely resemble multipotent mesenchymal stem cells (MSCs), raising the question of their origin and designating these cell popula...

Background: In the present study, we hypothesized that conditioned medium (CM) derived from mesenchymal stem cells attenuates the brain oxidative stress in sepsis induced by the cecal ligation and puncture (CLP) model. Methods: This study was performed in the Department of Physiology at Tehran University of Medical Sciences from August 2018 to April 2019. Conditioned medium was collected from ...
