background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...
bone marrow mesenchymal stem cells can differentiate into neurons and astrocytes after transplantation in the spinal cord injury of rats. although bone marrow mesenchymal stem cells are known to protect against spinal cord injury through anti-apoptotic effects, but generation of neural stem cells with large number and safety protocols unclear. in the present study, described the differentiation...
بررسی علل شیوع پان سیتوپنی در میان بیماران بستری بخش خون بیمارستان 501 ارتش بین سال های 1373 تا 1381
Background and Aim: Pancytopenia is the reduction of all 3 series of blood cells e.g. Erythroids, leukocytes, and platelets. The causes of pancytopenia are diverse. Some are related to bone marrow failure caused by toxins (Bone Marrow with no cells or low cells). Bone marrow may be infiltrated by malignant and foreign cells or bone marrow fibrosis. Genetics factor and geographical disease could...
In order to study the normal hematopoiesis, cellular components and myeloid/erythroid (M/E) ratio in the bone marrow of the pheasant (Phasianus colchicus), bone marrow samples were collected from the proximal tibiotarsus bone of 16 clinically healthy adult pheasant. The bone marrow smears were stained using the Giemsa stain. The results indicated that the development and formation of b...
Background and Objective: Cancers are among the serious problems in communities. In recent years, herbal products have been very promising regarding their anti-tumor and immunomodulatin potentials. SIM5, a herbal preparation, has had good results in discriminating between cancerous cell lines and normal cells, but have not examined directly on patients cells yet. In this study, bone marrow mono...
objective(s): although many researchers have confirmed induction of germ cells from bone marrow mesenchymal stem cells (bmmscs), there are no reports that confirm spontaneous differentiation of germ cells from bmmscs. in this study, we have evaluated the effect of adult sertoli cell condition medium (sccm) as a mutative factor in the induction of germ cells from bmmscs. materials and methods: b...
objective(s):to study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. materials and methods:forty new zealand rabbits were randomly divided into five groups with eight rabbits in each group. for each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. to t...
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...
stem cells are of great interest for regenerating disturbed tissues and organs. these cells are commonly isolated from the bone marrow, but there has been interest in other tissues in the recent years. in this study, we evaluated the possibility of isolation of stem cells from oral connective tissue and investigated their characteristics.in this experimental study, sampling from the bone marrow...
in order to study the normal hematopoiesis, cellular components and myeloid/erythroid (m/e) ratio in the bone marrow of the pheasant (phasianus colchicus), bone marrow samples were collected from the proximal tibiotarsus bone of 16 clinically healthy adult pheasant. the bone marrow smears were stained using the giemsa stain. the results indicated that the development and formation of blood cell...
