Abstract

We compared the effects of various combinations of cytokines (stem cell factor [SCF], interleukin [IL]-3, IL-6, granulocyte-colony stimulating factor [G-CSF], erythropoietin [EPO]) among the growth of human hematopoietic progenitor cells from cord blood (CB), bone marrow (BM), and peripheral blood mononuclear cells (MNC) mobilized by chemotherapy and G-CSF (PB) in a semi-solid medium. Macroscopic colonies, that were visible to the naked eye, were formed from PB-MNC within 1 week even without cytokines. They consisted of blasts containing macrophage-like cells with immature nuclei on Wright stain, and were strongly accelerated by IL-3. Macroscopic colonies were also formed from CB-MNC. However, they appeared after 1-3 weeks and synergistic effects of SCF with other cytokines, especially EPO, were prominent. Macroscopic colonies were not formed from BM-MNC. Granulocyte-colony stimulating factor was effective in increasing colony forming units of granulocyte macrophage from BM-MNC and they appeared between 1 and 2 weeks. These results suggested that the quality of hematopoietic progenitor cells was different among blood sources. This might lead to different bone marrow recovery patterns after transplantation of each blood source. ...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
