Proteolytic processing of histone H3 in chromatin: a physiologically regulated event in Tetrahymena micronuclei.

abstract：:Angiogenesis is an important event for embryonic organogenesis as well as for tissue repair in the adult. Here, we show that hematopoietic stem cells (HSCs) play important roles for angiogenesis during embryogenesis. To investigate the role of HSCs in endothelial cell (EC) development, we analyzed AML1-deficient embry...
