Absence of blood formation in mice lacking the T-cell leukaemia oncoprotein tal-1/SCL
CHROMOSOMAL translocations associated with malignancies often result in deregulated
expression of genes encoding transcription factors 1 . In human T-cell leukaemias such …

[HTML][HTML] A lineage‐selective knockout establishes the critical role of transcription factor GATA‐1 in megakaryocyte growth and platelet development
RA Shivdasani, Y Fujiwara, MA McDevitt… - The EMBO journal, 1997 - embopress.org
Transcription factor GATA‐1 is essential for red blood cell maturation and, therefore, for survival
of developing mouse embryos. GATA‐1 is also expressed in megakaryocytes, mast cells…

Dynamic visualization of thrombopoiesis within bone marrow
Platelets are generated from megakaryocytes (MKs) in mammalian bone marrow (BM) by
mechanisms that remain poorly understood. Here we describe the use of multiphoton intravital …
