abstract：:The cardiovascular system consists of many cell types with distinct embryonic origins. Cells from an Islet1 (Isl1)-expressing progenitor population make a substantial contribution to the developing heart. We reasoned that cells derived from Isl1-expressing progenitors might contribute more widely to the cardiovascular...
