Measurement of vulnerability to water stress-induced cavitation in grapevine: a comparison of four techniques applied to a long-vesseled species.

V. vinifera stems are far less vulnerable to water stress-induced cavitation than previously reported, and dehydration and long segment air-injection techniques are more appropriate for long-vesseled species and organs. Expand
Cardiac side population cells have a potential to migrate and differentiate into cardiomyocytes in vitro and in vivo

CSPs in injured heart differentiated into cardiomyocytes, endothelial cells, or smooth muscle cells, suggesting that CSPs are intrinsic cardiac stem cells and involved in the regeneration of diseased hearts. Expand
Evolutionary history of free-swimming and sessile lifestyles in urochordates as deduced from 18S rDNA molecular phylogeny.

- 1 September 1998
Molecular phylogenetic analyses of 18S rDNA of urochordates revealed a close relationship between salps and doliolids and paraphyly of the ascidians, and an early divergence of larvaceans is supported by the analyses. Expand
Details of the evolutionary history from invertebrates to vertebrates, as deduced from the sequences of 18S rDNA.
Phylogenetic comparisons of the sequences of 18S rDNA suggest the monophyly of the deuterostomes, with the exception of the chaetognaths, and support the hypothesis that chordates evolved from free-living ancestors. Expand
Tripartite organization of the ancestral chordate brain and the antiquity of placodes: insights from ascidian Pax-2/5/8, Hox and Otx genes.
The expression of HrPax-258 gene is reported: an ascidian homologue of vertebrate Pax-2, Pax-5 and Pax-8 genes, and it is suggested that this subfamily of Pax genes has conserved roles in regional specification of the brain. Expand
Adult cardiac Sca-1-positive cells differentiate into beating cardiomyocytes.

- 27 December 2013
It is demonstrated that Sca-1-positive cells in the adult murine heart have potential as stem cells and may contribute to the regeneration of injured hearts. Expand
Developmental expression of Pax1/9 genes in urochordate and hemichordate gills: insight into function and evolution of the pharyngeal epithelium.
The Pax1/9 genes might provide the first developmental genetic corroboration of hypotheses of organ-level homology that unifies hemichordates, urochordates and cephalochordates. Expand
Molecular evolution of fibrillar collagen in chordates, with implications for the evolution of vertebrate skeletons and chordate phylogeny
This study traced the molecular evolutionary history of chordate collagen genes and examined how gene duplications gave rise to the collagen genes used for skeletons, finding that one of the ascidian fibrillar collagen genes possesses an amino acid insertion at the identical site of the C‐terminal noncollagenous domain in vertebrates.

A novel role for dpp in the shaping of bivalve shells revealed in a conserved molluscan developmental program.
The cell cleavage and expression patterns of three genes, brachyury, engrailed, and dpp, in the Japanese spiny oyster Saccostrea kegaki are described and the function of dpp in this species is examined to elucidate the molecular developmental basis underlying this prominent morphological transition.

Patterning the protochordate neural tube
This work has identified both how the neural tube was patterned when it first evolved and what is truly novel in the vertebrate neural tube through a recent accumulation of gene-expression data. Expand
