introduction: a number of potential cell adhesion molecules, which mediate essential cell-to-cell or cell-to-matrix interactions, are expressed on the surface of cd34+ hematopoietic progenitor cells (hpcs), including integrins, cd44, and cxcr4. these molecules are essential for homing process. in this study, we compared the changes of expression of cd44 and cxcr4 on the cd34+ hematopoietic prog...

background: acute myeloid leukemia (aml) is an immunophenotypically heterogeneous malignant disease, in which cd34 positivity is associated with poor prognosis. osteopontin (opn) plays different roles in physiologic and pathologic conditions like: survival, metastasis and cell protection from cytotoxic and apoptotic stimuli. due to anti-apoptotic effect of opn in normal and malignant cells, sil...

objective: allogeneic transplantation with umbilical cord blood (ucb) in adult recipients is limited mainly by a low cd34+ cell dose. to overcome this shortcoming, human placenta as a novel source of human mesenchymal progenitor cell (mpc)- unrestricted somatic stem cells (ussc)- was incorporated in an attempt to expand cd34+ cells from ucb. to provide a similar environment in vitro, we coated ...
