Key clinical point: Bone marrow stromal cells in patients with myelodysplastic syndromes and acute myeloid leukemia showed a reduced frequency of colony forming unit-fibroblasts.
Major finding: The frequencies of positive/positive bone marrow stromal cells were significantly lower in AML patient samples compared to healthy individuals and MDS bone marrow samples. The median cell numbers of bone marrow stromal cells in diagnostic samples were 3,200 for healthy samples, 476 for MDS samples, and 70 for AML samples.
Study details: The data come from bone marrow samples in AML patients, MDS patients, and healthy donors.
Disclosures: The study was supported in part by Projekt DEAL and the Deutsche Forschungsgemeinschaft SFB 1243 for projects A09 and the FOR2033 project B3, as well as the Deutsche Jose Carreras Leukämie Stiftung. The researchers had no financial conflicts to disclose.
