This study represents the first demonstration of cell migration in response to an artificial ligand that is quite different from natural chemoattractants, suggesting its potential application to immunotherapies and tissue engineering.
In a demonstration of cell surface marker quantitation a comparison study of 118 blood samples showed a correlation coefficient of 0.94 for Accellix determined neutrophil CD64 compared to those determined using a FACS.
Afterwards, five recommended applications are discussed in detail, namely the capability to extract the actual I V characteristic and its comparison to the one provided by the manufacturer, the determination of the P–I characteristic of the module, the demonstration of cell shading experimentation, the determination of a module's optimal tilt angle and finally the translation of I V curves.
However, SEB-treated cervical cells from both HIV-infected and uninfected women may sometimes be unresponsive in flow cytometry-based assays despite the demonstration of cell viability via a live/dead gating strategy (unpublished; McKinnon L and Kaul R), and so a lack of cell viability is unlikely to explain these results.
A key step in the drug discovery process is demonstration of cell permeability and in vivo efficacy.
This could be the possible mechanism behind the vancomycin resistant staphylococcal isolates that we have reported though we could not perform the test for the demonstration of cell wall thickening in these isolates.
In light of this first demonstration of cell cycle-regulated capsulation and the importance of capsule in masking, preventing, or impeding immune responses in bacterial pathogens, our results raise the intriguing possibility of targeting specifically the G1-phase regulatory hierarchy to combat bacterial infections by crippling encapsulation mechanisms.
We have established two growth plate-derived chondrocyte cell lines, MMR14 and MMR17, from p53−/− mice (Nakamata T, Aoyama T, Okamoto T, Hosaka T, Nishijo K, Nakayama T, et al. In vitro demonstration of cell-to-cell interaction in growth plate cartilage using chondrocytes established from p53−/− mice. J Bone Miner Res 2003 18 97 107).
Since this strategy does not involve xeno-transplantation, such an approach would allow the first in situ demonstration of cells with stem cell properties within established tumours.
