However, this technique is only suitable for large calibre vessels (>3 mm) and carries doubt about the precise patten of intima-to-intima alignment of vessels.
Furthermore, by experimenting with the alignment of the vessel to the current at the tidal stream site in Guernsey, it was possible to achieve sampling at currents up to 1.5 ms-1, this time by steaming into the current at an appropriate angle, allowing the vessel to drift.
In the remaining 5 maps we determined the location of the imaging site relative to the barrel using alignment of vertical blood vessels.
The close alignment of nerves and vessels throughout the body plan could be achieved in one of two ways: either by shared patterning mechanisms or by axons acting to guide vessels (or vice versa).
Sectioning showed that the Scrib f/f PGK-Cre embryos developed heart malf/f PGK-Creincluding abnormalitiembryoshe ventricular myocardevelopedgnment of thearttflow vessels with the ventricular chamalformationsnormal posincludingof the heabnormalitiesest, recapinulatheg those seen in Crc mutants.
In E10.5 embryo4/ΔEx4 embrainsrains we failed to detect a normal alignment and invasion of vessels from the perineural vascular plexus into the developing ganglionic eminence, as seen in the controls (Fig. 6C,D, arrowheads).
To examine the alignment of neurons and blood vessels during zebrafish embryogenesis, we monitored the development of neurons and blood vessels simultaneously using transgenic (Tg) fish expressing Myr-mCherry in blood vessels under the fli1a promoter and GFP in neurons under the huc promoter Tg(fli1a:myr-mcherry);(huc gfp) (Park et al., 2000).
Membranous ventricular septum defects can be caused by reduced contribution of the cardiac neural crest or second heart field to the outflow tract, resulting in aberrant alignment of the outflow tract vessels, or defects in endothelial-to-mesenchymal transformation and maturation of the cardiac cushions.
Several vascularization models have consistently found that the stress generated in the gel, and encountered by embedded cells, control various aspects of vascular network formation, including sprouting, branching, alignment, and vessel maturation.
A histopathological study revealed fibrous band formation inside the tumor, trabecular alignment of tumor cells, mitotic figures, and capsule/blood vessel invasions as described in the criteria proposed by Schantz and Castleman [14] and compatible with those of parathyroid carcinoma.
