    Evaluation of CD34+ - and Lin- -selected cells from peripheral blood stem cell grafts of patients with lymphoma during differentiation in culture ex vivo using a cDNA microarray technique

  • Original language description

    Objective. Hematopoietic stem cells (enriched in fraction of CD34+ cells) have the ability to regenerate hematopoiesis in all of its lineages, and this potential is clinically used in transplanting bone marrow or peripheral blood stem cells. Our objective was to assemble a suitable method for evaluating gene expression in enriched populations of hematopoietic stem cells. We compared biologic properties of cells cultured ex vivo obtained using two different ways of immunomagnetic separation (positive selection of CD34+ cells and negative selection of Lin2 cells) by means of a cDNA microarray technique. Methods. CD34+ and Lin2 cells were enriched from peripheral blood stem cell (PBSCs) grafts of patients with non-Hodgkins lymphoma. Isolated cells were inthe presence of cytokine PBSCs, FLT-3 ligand, interleukin-3, interleukin-6, and granulocyte colony-stimulating factor. At days 0, 4, 6, 8, 10, 12, and 14 cells were harvested and analyzed by cDNA microarrays. Total cell expansion, CD34+,

    Analýza CD34+ a Lin- kmenových buněk z periferních krve pacientů s lymfomem během ex vivo diferenciace v kultuře pomocí techniky DNA microarray

  • Czech description

    Cíl. Hematopoetické kmenové buňky (frakce CD34+) mají schopnost diferencovat do všech typů krevních buněk a tato schopnost je využívána při transplantacích kostí dřeně a kmenových buněk z periferní krve. Naším cílem bylo vypracovat vhodnou metodu pro stanovení genové exprese v populacích hematopoetických kmenových buněk. Technikou cDNA microarrays jsme porovnávali biologické vlastnosti buněk kultivovaných ex vivo, které byly získány za použití dvou rozdílných metod imunomagnetické separace (pozitivní selekce CD34+ buněk a negativní selekce Lin-). Metody. CD34+ a Lin- buňky jsme izolovali z kmenových buněk z periferní krve (PBSCs) pacientů s non-Hodkingovým lymfomem. Buňky byly vystaveny působení cytokinu PBSCs, FLT-3 ligandu, interleukinu-3, interleukinu-6 a granulocytárnímu faktoru stimulujícímu kolonie. Odběry a analýza buněk na cDNA microarrays proběhly ve dnech 0, 4, 6, 8, 10, 12 a 14. Byla též analyzována totální buněčná expanze, CD34+, colony-forming unit pro granulocyt-makrofágo
