Desperately seeking a home marrow niche for T-cell acute lymphoblastic Leukaemia

T-ALL is commonly thought to originate from the thymus albeit recent literature describes the possible acquisition of first oncogenic hits in hematopoietic progenitor cells of the bone marrow (BM). The journey of T-ALL from its arising to full blown expansion meets different microenvironments, including the BM in which leukemic cells settle down early after the disease spreading. We take advantage of recent literature to give an overview of important cells and factors that participate in T-ALL, especially in the BM, arguing in favor of a home marrow niche for this rare leukemia.
