PURPOSE OF REVIEW Umbilical cord haematopoietic stem cell transplantation for primary immunodeficiencies is examined with other developments in treatment. Cord blood biology is reviewed, and advantages and disadvantages of umbilical cord blood stem cell transplantation for primary immunodeficiencies discussed. Clinical outcome data and future developments are reviewed. RECENT FINDINGS Cord bl...

stem cells are naïve or master cells. this means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. stem cells are found in many parts of the human body, although some sources have richer concentrations than others. some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and hu...

in this center, from 1991 to 2002, 89 chronic myelogenous leukemic (cml) patients, age ranging between 8-48 years with a median age of 29, underwent hematopoietic stem cell transplantation. eighty-eight patients were in the first chronic phase of disease. twenty-three patients received bone marrow transplantation (bmt) and 66 patients received peripheral blood stem cell transplantations (pbsct)...

introduction: the use of cord stem cells, as a cell source for bone marrow reconstruction in patient under hematopoietic stem cell transplantation is enhancing. the amount of cd34+cells collected from cord blood compared to peripheral blood and bone marrow are less, but their collectionprocesure is easier. delay in freezing has negative effect on cells surveillance and reduce their ability in t...

conclusions our results suggested that cb-nk cells progenitors could proliferate and differentiate on feeder layer of amnion membrane mscs in combination with specific cytokines to produce nk cells for immunotherapy. results combination of cytokines and msc layer yielded significant fold expansion in comparison with cytokines without feeder conditions (day 7: 5.2 ± 1.12 and 2 ± 0.78, respective...

introduction: neuroblastoma is the most common extracranial solid tumor in children, accounting for 8% to 10% of all childhood cancers. significantly, autologous transplantation appeared to have the largest impact on survival for the high risk subset of patients, such as those with n-myc amplified metastatic disease diagnosed after age 2 years. patients and methods: this study includes high ris...

peripheral blood stem cell transplantation (pbsct) is an effective treatment for hematological malignancies. mobilization of peripheral blood progenitor cells performs in different ways among transplantation centers. forceful mobilization schedules are comprised of growth factor alone, chemotherapy along with growth factor and also, a newly combination of novel agent such as plerixafor with any...

a:4:{s:10:"Background";s:2314:"The research made on stem cells through the last decade and following that the great achievements made applying stem cells in treating vast number of diseases have turned the issue of Cord Blood collecting and saving (cryopreserving) to a critical one. A prompt demand and access to stem cells and applying them in treating a wide range of terminal diseases have led...

stem cell therapy can be useful for spinal cord injury (sci). induced pluripotent stem cells (ipscs) are generated by reprogramming mature, fully differentiated cells into a pluripotent state. the ability to generate pluripotent cells from adult somatic cells without the need for an embryo was a major development in stem cell biology. ipscs were established from mouse fibroblasts and demonstrat...
