abstract = {Recent studies in animal models provided proof-of-principle
evidence for cell transplantation as a potential future
therapeutic approach for retinal pathologies in humans such
as Retinitis pigmentosa or age-related macular degeneration.
In this case, donor cells are injected into the eye in order
to protect or replace degenerating photoreceptors or retinal
pigment epithelium. However, currently there is no
three-dimensional imaging technique available that allows
tracking of cell migration and integration into the host
tissue under in vivo conditions. Therefore, we investigate
about magnetomotive optical coherence tomography (OCT) of
substances labeled with iron oxide nanoparticles as a
potential method for noninvasive, three-dimensional cell
tracking in the retina. We use a self-developed spectral
domain OCT system for high-resolution imaging in the 800
nm-wavelength region. A suitable AC magnetic field for
magnetomotive imaging was generated using two different
setups, which consist of an electrically driven solenoid in
combination with a permanent magnet, and a mechanically
driven all-permanent magnet configuration. In the sample
region the maximum magnetic flux density was 100 mT for both
setups, with a field gradient of 9 T/m and 13 T/m for the
solenoid and the allpermanent magnet setup, respectively.
Magnetomotive OCT imaging was performed in elastic tissue
phantoms and single cells labeled with iron oxide
nanoparticles. Particle-induced sub-resolution movement of
the elastic samples and the single cells could successfully
be detected and visualized by means of phase-resolved
Doppler OCT analysis. Therefore, this method is a potential
technique to enhance image contrast of specific cells in
OCT.},
