Developmental Biology 

TL;DR: It is concluded that the cell lineage itself, complex as it is, plays an important role in determining cell fate and is demonstrated to demonstrate substantial cell autonomy in at least some sections of embryogenesis.

TL;DR: These cell lineages range in length from one to eight sequential divisions and lead to significant developmental changes in the neuronal, muscular, hypodermal, and digestive systems and are determined by direct observation of the divisions, migrations, and deaths of individual cells in living nematodes.

TL;DR: More than 50% of miRNA genes are located in cancer-associated genomic regions or in fragile sites, suggesting that miRNAs may play a more important role in the pathogenesis of a limited range of human cancers than previously thought.

TL;DR: It is found that the zebrafish fli1 promoter is able to drive expression of enhanced green fluorescent protein (EGFP) in all blood vessels throughout embryogenesis, and these transgenic lines allow detailed analysis of both wild type and mutant embryonic vasculature.

TL;DR: The clonal derivation of two human ES cell lines, H9.1 and H.2, demonstrates the pluripotency of single human ES cells, the maintenance of pluripOTency during an extended period of culture, and the long-term self-renewing properties of cultured human ES Cells.
