text_1: Differentiation of progenitor cells to myeloid cells is skewed when insulin signaling is suppressed.
text_2: Here, we show that the haematopoietic progenitors of Drosophila are direct targets of systemic (insulin) and nutritional (essential amino acid) signals, and that these systemic signals maintain the progenitors by promoting Wingless (WNT in mammals) signalling.
