A successful graft requires stem cells--a component of bone marrow which has the ability to reproduce itself indefinitely--from a genetically compatible donor to be infused into a vein; once in the bloodstream, the cells will home in on the marrow space.
Two weeks later, his bone marrow, which had been full of leukemia cells, was clean, a biopsy showed.
About 10,000 of the 16,000 Americans who got marrow transplants last year used their own marrow, which had been taken out before chemotherapy and cleaned of cancer cells.
After the first 2 cycles of treatment, an additional clone characterized by loss of the Y chromosome was detected in the marrow, which had not been described prior to study treatment and increased to 53% of metaphases after 5 cycles.
Recently, we have compared gene expression changes in MSC from human bone marrow, which had been isolated in two different laboratories, grown in long-term culture with different culture media and subsequently also analyzed with different microarray platforms [ 38].
This would negate the need for sourcing autologous cells, for example, from adipose tissue or bone marrow, which have associated problems of donor site morbidity and limited cell number.
To optimize transfection efficiencies and cell survival we tested several other nucleofector kits (Basic Nucleofector Kit for Primary Mammalian Epithelial Cells and Cell Line Nucleofector Kit T for Bone Marrow) which have been used to transfect primary cells from other tissues.
A major area of investigation is the human bone marrow microenvironment, which has an essential role in promoting growth, survival, and drug resistance in MM.
Mesenchymal stem cells (MSCs) were first discovered in bone marrow (BMSCs), which have a strong proliferative capacity and can be differentiated into adipocytes [ 1, 2], osteoblasts [ 3– 5], myoblasts [ 6– 8], and neurons [ 9, 10].
However, radiography is more helpful in detecting trabecular/cortical bone lesions while MRI is more sensitive, particularly in the vertebral bone marrow, to show diffuse or focal bone marrow involvement, which has not or not yet caused destruction of mineralised bone.
