| Research Abstract |
Transient myeloproliferative disorder (TMD) in neonates with Down syndrome is a special leukemia that arises in fetal stage and spontaneously regresses after birth. We studied the role of hematopoietic microenvironment in spontaneous remission of TMD. In the presence of growth factors, TMD blasts differentiated into basophil/mast cell and megakaryocyte lineages and aberrant expression of GATA1 protein due to GATA1 mutations was shown to be down-regulated during differentiation. The growth of TMD blasts was maintained by stromal cells of the fetal liver. These data indicate that differentiation potential of TMD blasts and fetal hematopoietic microenvironment could be involved in spontaneous remission of TMD.
