10.7554/eLife.30668.001 During vertebrate heart development, two progenitor populations,
first and second heart fields (FHF, SHF), sequentially contribute to longitudinal subdivisions …

The first blood and endothelial cells of amniote embryos appear in close association in the
blood islands of the yolk sac (YS). This association and in vitro lineage analyses have …

The mammalian heart contains multiple cell types that appear progressively during embryonic
development. Advance in determining cardiac lineage diversification has often been …

Meis1 and Meis2 are homeodomain transcription factors that regulate organogenesis through
cooperation with Hox proteins. Elimination of Meis genes after limb induction has shown …

Understanding organ morphogenesis requires a precise geometrical description of the
tissues involved in the process. The high morphological variability in mammalian embryos …

Tracing and manipulating cells in embryos are essential to understand development. Lipophilic
dye microinjections, viral transfection and iontophoresis have been key to map the origin …

The contractile ability of the mammalian heart critically relies on blood coronary circulation,
essential to provide oxygen and nutrients to myocardial cells. In addition, the lymphatic …

Understanding the diversification of mammalian cell lineages is an essential to embryonic
development, organ regeneration and tissue engineering. Shortly after implantation in the …

… We thank Susana Temino for excellent technical assistance, M. Guerrero for CGH
analysis, and Amaia Lujambio for help with expression assays. We also thank I. …

For most of its history, archaeology has too often taken an indulgent attitude toward looting
and antiquities trafficking. The primary response to these dangers has been to publish the …
