From the combination of immunocytochemical and immunfluorescence labeling procedures and direct observations by phase contrast microscopy, it appeared that the there was minimal disturbance to the mammalian cells situated directly beneath the C. albicans colonies.
Based on inspection by confocal microscopy, it appeared that in murine CTL clones and CD8+ T and NK cell blasts, FasL does not or only partially colocalise with standard lysosomal markers including CD63 and Lamp-1 or the cytotoxic effector molecules granzyme B and perforin.
We were unable to precisely resolve the channel opening corner radius of the channel opening using light microscopy, but it appeared to be <0.02Rc, so we used a corner radius of 0.02Rc in our simulations.
The even distribution of raft markers at the cell surface as it appears in light microscopy is dramatically altered upon crosslinking of raft proteins and lipids.
In conclusion, on the basis of the current information, it appears that urine microscopy and new urine biomarkers may be used together to inform on early AKI, differentiate pre-renal AKI from ATN, and predict progressive AKI, need for RRT and death.
This approximation was validated using electron microscopy and appears to provide good values.
Combined SHG/2PEF microscopy therefore appears as a promising technique to simultaneously observe collagen self-assembly and cells behavior in biological samples.
Compared to TEM that is characterized by very high resolution but limited field of view (few 10 µm), SHG microscopy thus appears as a complementary technique that is sensitive enough to image small collagen fibrils while providing an extended field of view (few 100 µm to 1 mm).
Cells were harvested from bacterial growth plates and incubated in Loflo medium plus TRITC-dextran for 30 min then imaged by confocal microscopy; cells' cytoplasm appears dark since no dextran penetrates it while endosomes are bright as their contents become concentrated.
With these probes, near-field microscopy appears poised to fulfill its promise by combining the power of optical characterization methods with nanometric spatial resolution.
