Recently, the differential localization of cadherins along junctions with different orientations was shown to direct the flow of actin and myosin from the cell apex towards those junctions.
A related question is what controls the orientation of polymerization to direct the forces that drive membrane invagination and vesicle scission.
Further modifications to stretched microthreads, such as carbodiimide crosslinking, could generate microthreads to direct cell orientation and align tissue deposition, with additional resistance to degradation for use as a long-term scaffold for tissue regeneration.
In particular we discuss the role of linker length between V-domains and the orientation of the V-domains to direct the formation of either diabodies (60 kDa), triabodies (90 kDa) or tetrabodies (120 kDa), and how the size, flexibility and valency of each molecules is suited to different applications for in vivo imaging and therapy.
Peptides were secured to slides by biotin-streptavidin interactions rather than other types of slide surfaces to direct the orientation of peptides and to provide sufficient space from the surface to allow for ligand-recognition (data not shown).
In addition, the fibrous structure of the PCL-gelatin alone served to direct cell orientation in a 2D aligned electrospun fiber mat, similar to other studies described above.
For between copy primers the sequences were cut in half and pasted in a reverse orientation to generate properly directed primer sets.
Hence, this could also involve an siRNA-dependent mechanism, whereby the LCR induces transcripts within flanking sequences in the opposite orientation to convergent transcripts directed by the transgene promoter [ 33].
Representing ECM fibers as static obstacles they demonstrate how ECM fibers distributed in uniform or directionally-biased random orientations can direct the migration of a growing angiogenic sprout.
Furthermore, in the horizontal SMFs, cell orientation tended to deviate from nanofiber orientation to field direction while the nanofiber orientation is perpendicular to the field direction, while the horizonal direction of SMFs could also direct the cell growth orientation.
