… 2a,b). Progenitors then begin to express cardiac transcription factors such as GATA4/5/6,
Nkx2-5, Mef2B/C, and Tbx5/20, and a primitive myogenic program is activated (Harvey 2002a). …

… We generated Cxcr7 −/− mice but found that CXCR7 deficiency had little effect on B cell …
PCR in human (B) and murine (C) T and B cells relative to naive or follicular (FO) B cells, …

… (B–D) The gene for Tbx5 is expressed in the cardiac crescent of E8 (B) and in the linear heart
of E8.5 (C) embryos, in an anteroposterior gradient. This gradient is essentially unchanged …

During heart development the second heart field (SHF) provides progenitor cells for most
cardiomyocytes and expresses the homeodomain factor Nkx2-5. We now show that feedback …

NKX2-5 is expressed in the heart throughout life. We targeted eGFP sequences to the NKX2-5
locus of human embryonic stem cells (hESCs); NKX2-5 eGFP/w hESCs facilitate …

… clonogenic cells that could also give rise to the spectrum of colony types (Figure S1A), but
were capable of only slow and short-term growth ($2 months; four passages; Figure 1B) and …

Heterozygous mutations in the cardiac homeobox gene, NKX2-5, underlie familial cases of
atrial septal defect (ASD) with severe atrioventricular conduction block. In this study, mice …

… B1–B3 in Appendix B. The vectors of the reciprocal basis are given by Ei=gijEj see expression
B4 in Appendix B; we use the Einstein summation convention throughout. We are now in …

On the basis of thermodynamically self-consistent integral equations for the pair structure it
is shown that dense binary mixtures of hard spheres, of diameters σ 1 and σ 2, phase …

One of the first morphological manifestations of left/right (L/R) asymmetry in mammalian
embryos is a pronounced rightward looping of the linear heart tube. The direction of looping is …
