Gene expression profile of murine long-term reconstituting vs. short-term reconstituting hematopoietic stem cells.
The hematopoietic stem cell (HSC) compartment is composed of long-term reconstituting (LTR) and short-term reconstituting (STR) stem cells. LTR HSC can reconstitute the hematopoietic system for life, whereas STR HSC can sustain hematopoiesis for only a few weeks in the mouse. Several excellent gene expression profiles have been obtained of the total hematopoietic stem cell population. We have u...
متن کاملHOXB4-Induced Expansion of Adult Hematopoietic Stem Cells Ex Vivo
Hox transcription factors have emerged as important regulators of primitive hematopoietic cell proliferation and differentiation. In particular, HOXB4 appears to be a strong positive regulator of hematopoietic stem cell (HSC) self-renewal. Here we demonstrate the potency of HOXB4 to enable high-level ex vivo HSC expansion. Cultures of nontransduced or GFP-transduced murine bone marrow cells exp...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولOverexpression of HOXB4 enhances the hematopoietic potential of embryonic stem cells differentiated in vitro.
Little is known about the molecular mechanisms controlling primitive hematopoietic stem cells, especially during embryogenesis. Homeobox genes encode a family of transcription factors that have gained increasing attention as master regulators of developmental processes and recently have been implicated in the differentiation and proliferation of hematopoietic cells. Several Hox homeobox genes a...
متن کاملGeneration of hematopoietic repopulating cells from human embryonic stem cells independent of ectopic HOXB4 expression
Despite the need for alternative sources of human hematopoietic stem cells (HSCs), the functional capacity of hematopoietic cells generated from human embryonic stem cells (hESCs) has yet to be evaluated and compared with adult sources. Here, we report that somatic and hESC-derived hematopoietic cells have similar phenotype and in vitro clonogenic progenitor activity. However, in contrast with ...
