embryonic stem cells (escs) as pluripotent stem cells have the potential to give rise to all three germ layer cells. also, these cells have the self-renewing ability. escs could differentiate into most of cell lineages. lymphocytes generated from hematopoietic stem cells. we designed a feeder free culture condition to generate lymphoid lineage cells from escs. we demonstrated that il-7 plays cr...

Background The piwi family genes are highly conserved during evolution and play a crucial role in stem cell self-renewal, gametogenesis, and RNA interference in diverse organisms ranging from Arabidopsis to humans. Piwil2, also known as Hili, is one of the four human homologues of piwi. Piwil2 was found in germ cells of adult testis, suggesting that this gene functions in spermatogonial stem ce...

We present phylogenetic results for Justicieae, the largest of major lineages Acanthaceae. With 300% more sequence data and a similarly increased but also geographically representative taxon sample compared to only previous study lineage as whole, we confirm existence Pseuderanthemum Lineage, Isoglossinae, Tetramerium Lineage Justicioid Lineage. To last three lineages, add number taxa with goal...

introduction: enrichment of intact peripheral blood dendritic cells (dcs) has been done using rosette and immunomagnetic depletion techniques. material and methods: peripheral blood mononuclear cells were separated using ficoll density gradient centrifugation and t lymphocytes were depleted through reaction with aet- treated sheep red blood cells. the remaining cells were depleted from lineage ...

Introduction: Acute Leukemia with Mixed Lineage phenotype (MLL) is leukemia that consists of cells characterized by mixed lineage markers, both from myeloid and lymphoid cells. The incidence this only 2-5% all acute leukemias considered to have a poor prognosis.Case Presentation: A seven-year-old girl was diagnosed MLL. results immunophenotyping showed two blast populations the expressions CD33...

Background: Despite several studies many questions remain regarding how varicocele develops its adverse effect on testicular tissue. Spermatogenesis cell lineage needs carbohydrates as a main source of energy for cell division. Any disruption in glucose transporting system in seminiferous tubules results in remarkable decrease in germinal cells biological function. Therefore present study was c...
