In this study, we investigated CDw90 (Thy-1) expression in CD34+ cells and hematopoietic colony-forming ability in purified CD34+ Thy-1+ and CD34+ Thy-1 fractions in the peripheral blood at the PBSCH. The high proliferative potential colony-forming cells (HPP-CFC), which are considered to be more primitive hematopoietic stem cells, were found more frequently in the purified CD34+ Thy-1+ fraction than in the purified CD34+ Thy-1- fraction. Thus, it is useful to decide the optimal time of PBSCH to measure the CD34+ Thy-1+ cells as well as CD34+ cells in the peripheral blood by flow-cytometry. In CD34+ acute myeloblastic leukemia (AML) cells, the co-expression rate of CD34 and Thy-1 was negative, suggesting that it may be possible to estimate the contamination of CD34+ AML cells by the Thy-1 expression rate in CD34+ cells at PBSCH.

D016179 Granulocyte Colony-Stimulating Factor A glycoprotein of MW 25 kDa containing internal disulfide bonds. It induces the survival, proliferation, and differentiation of neutrophilic granulocyte precursor cells and functionally activates mature blood neutrophils. Among the family of colony-stimulating factors, G-CSF is the most potent inducer of terminal differentiation to granulocytes and macrophages of leukemic myeloid cell lines.

D018380 Hematopoietic Stem Cell Transplantation Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
