هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
spinal cord injury (sci) is a debilitating disease which leads to progressive functional damages. because of limited axonal regeneration in the central nervous system, there is no or little recovery expected in the patients. different cellular and molecular approaches were investigated in sci animal models. cellular transplantation of stem cells can potentially replace damaged tissue and provid...
background: cell therapy has emerged as a promising curative intervention for several diseases including diabetes and wolfram syndrome (ws). the current study aimed to assess the effectiveness of clinical application of fetal-liver derived stem cells for treatment of patients with ws. methods: six patients with ws aged 23-34 (mean: 29.50, sd: 4.76) were recruited for the current phase 3 single-...
BACKGROUND The global gene expression profiles of adult and fetal murine prostate stem cells were determined to define common and unique regulators whose misexpression might play a role in the development of prostate cancer. METHODOLOGY/PRINCIPAL FINDINGS A distinctive core of transcriptional regulators common to both fetal and adult primitive prostate cells was identified as well as molecule...
Understanding the identity of lineage-specific cells arising during manipulations of stem cells is necessary for developing their potential applications. For instance, replacement of crucial functions in organ failure by transplantation of suitable stem-cell-derived cells will be applicable to numerous disorders, but requires insights into the origin, function and fate of specific cell populati...
Many investigators have used xenogeneic, especially murine stromal cells and fetal calf serum to maintain and expand human stem cells. The proliferation and expansion of human hematopoietic stem cells in ex vivo culture were examined with the goal of generating a suitable protocol for expanding hematopoietic stem cells for patient transplantation. Using primary fetal liver cells, we established...
introduction: umbilical cord blood (cb) has been identified as a rich source for hematopoietic stem cells (hscs), and has provided an alternative to bone marrow transplantation. the use of ex vivo expanded cells has been suggested as a possible means to accelerate the speed of engraftment in cord blood (cb) transplantation. the main aim of our study is to find the best culture media and conditi...
Data from many laboratory and clinical investigations indicate that CD34+ cells comprise approximately 1% of human bone marrow (BM) mononuclear cells, including the progenitor cells of all the lymphohematopoietic lineages and lymphohematopoietic stem cells (stem cells). Because stem cells are an important but rare cell type in the CD34+ cell population, investigators have subdivided the CD34+ c...
Fetal growth plays a role in programming of adult cardiometabolic disorders, which in men, are associated with lowered testosterone levels. Fetal growth and fetal androgen exposure can also predetermine testosterone levels in men, although how is unknown, because the adult Leydig cells (ALCs) that produce testosterone do not differentiate until puberty. To explain this conundrum, we hypothesize...
