Background and Aim: Embryonic stem cells are identified with two unique characteristics. First, they can be maintained and expanded as pure populations of undifferentiated cells, a characteristic which is known as self renewal aspect of embryonic stem cells. Second, these cells can give rise to all body cell types. In the current study, we used a feeder-free condition to differentiate mouse emb...
Embryonic stem cells are pluripotent stem cells which have the ability to indefinitely self-renew and differentiate into all differentiated cells of the body. Regarding their two main properties (unlimited self-renewal and multi-lineage differentiation), these cells have various biomedical applications in basic research and cell based therapy. Because the transplantation of differentiated cells...
the aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. blastocyst stage embryos from pregnant nmri mice were obtained and cultured for 1-2 days in dmem medium. the inner cell masses formed...
background: embryonic stem cells (esc) are pluripotent cells which have been used as a model to study the mechanism that control the embryogenesis and early mammalian development in vitro. the aim of this study was to isolate and produce embryonic stem cells from late blastocyst stage embryos in mice. materials and methods: blastocyst stage embryos from pregnant nmri mice were obtained and cult...
introduction: the aim of this study was evaluate the ability of notochord to induce neural induction and/or differentiation of mouse embryonic stem cell to neuron and motor neuron, respectively. methods: in order to produce embryoid bodies, es cells line royan b1 were grown in suspension in the absence of lif for 4 days. ebs were divided into 4 groups. ebs in group 1 & 2 were further cultured i...
background: diabetes mellitus (dm), simply known as diabetes, refers to a group of metabolic diseases in which there are high blood sugar levels over a prolonged period. in this study, the feasibility and safety of intravenous transplantation of very small embryonic like stem cells (vsels) were investigated for diabetes repair, and finally the migration and distribution of these cells in hosts ...
The aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. Blastocyst stage embryos from pregnant NMRI mice were obtained and cultured for 1-2 days in DMEM medium. The inner cell masses formed...
The extract of pluripotent stem cells induces dedifferentiation of somatic cells with restricted plasticity. In this study, we used the extract of human embryonic stem cells (hESC) to dedifferentiate adipose tissue-derived stem cells (ADSCs) and examined the impact of this reprogramming event on dopaminergic differentiation of the cells. For this purpose, cytoplasmic extract of ESCs was prepare...
introduction: type i diabetes mellitus is caused by autoimmune destruction of the insulin-producing β-cells. a new potential method for curing the disease is transplantation of differentiated insulin- secreting cells from human embryonic stem cells. methods: human embryonic stem cell lines (royan h1) were used to produce embryoid bodies. differentiation carried out by growth factor-mediated sel...
introduction cholinergic system is one of the important systems of mammalian cns. cholinergic neurons distributed in brain and spinal cord and contributed to principal functions like: consciousness, learning and memory, and motor control. in this study we investigated the differentiation potentiality of mouse embryonic stem cells toward cholinergic neurons. the aim of this study was to evaluate...
