background the ability to follow the distribution and migration of biologically active cells in human is essential for the development of cell-based therapies and diagnostics. nuclear medicine imaging is widely applied in clinic as an attractive technique for in vivo wbc and stem cell tracking. the aim of this study was to evaluate prosthesis infection of a 51 years old man with previous histor...

background the aim of this clinical trial was the assessment of safety and efficacy of submocosal and periurethral injections of peripheral blood derived autologous stem cells along with platelets, and focused on outcome for six months. methods an open, prospective study was conducted on 10 patients presenting with stress urinary incontinence. at the baseline (pre-operative), 1, 3 and 6 months ...

stem cells are undifferentiated self regenerating multi potential cells. there are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. totipotent: these stem cells can form an entire organism such as fertilized egg. ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organis...

stem cells are cells with the ability to divide for indefinite periods and to give rise to specialized cells.  stem cell therapy has now been emerged as an extraordinary promise to treat a wide range of diseases and conditions.  however, except blood stem cell transfer by bone marrow transplant which has been used as an standard practice for more than 50 years, nearly all of therapeutic potenti...

introduction to evaluate the expression patterns of cytokeratin (k) 12, 13, and 19 in normal epithelium of the human ocular surface to determine whether k13 could be used as a marker for conjunctival epithelium. methods: total rna was isolated from the human conjunctiva and central cornea. those transcripts that had threefolds or higher expression levels in the conjunctiva than the cornea were ...

there is increasing trend in using recombinant stem cells as novel therapeutic candidates in different diseases. these studies encompass different applications from targeted homing of mesenchymal stromal (stem) cells (msc), to arming them with different cytokines. resistance to transfection or transduction methods had urged researchers to look for better gene delivery alternates and optimizing ...

background: keratinocyte stem cell is one of the adult stem cells that inhabits the skin and contributes to skin function and renewal. adult stem cells are best defined by their capacity to self-renew, and to maintain tissue function for a long period of time. these findings indicate the importance of these cells for clinical applications including regenerative medicine, tissue engineering and ...

clinical applications of mesenchymal stem cells (mscs) rely on their capacity to home and engraft in the appropriate target tissues for a long time. homing and engraftment capacity of these stem cells depend on the expression of chemokines and their receptors. ex vivo expanded mscs exhibit homing potential when grafted to injury tissue but their homing efficiency has been observed very poor bec...

thalassemia is an autosomal recessive disorder associated with defective synthesis of the α- or β-chain of hemoglobin. for β-thalassemia major patients, therapeutic options are either monthly red cell transfusions and chelation therapy or allogeneic stem cell transplant. stem cell transplant is the only curative approach and success is inversely correlated with the degree of iron overload and h...

trying to use embryonic stem cells about 20 years ago, working with animals,  especially rats began. during these years , many experiments in mouse embryonic stem cells to transform into a variety of cells and transplanting them were led to remarkable success . in the next issue of human stem cells were considered successful until finally in 1998 the first report was published in the proliferat...
