For example, in a mouse model of multiple sclerosis, only females exhibit neuropathic pain (sensitivity to mechanical, cold, and heat stimulation), even when motor dysfunction does not differ between the sexes [ 141].
In contrast, administration of rAAV sox9 did not modulate the proliferative processes in the samples over time versus control treatments in any of the systems evaluated (even though mechanical stimulation led to increased activities), again consistent with the known activities of SOX9 (Akiyama et al. 2004) and with our findings in isolated human bone marrow-derived MSCs (Venkatesan et al. 2012).
Even minor chemical or mechanical stimulation of the sensitized trigeminal nerve also causes excessive excitement.
Interestingly, mechanical stimulation resulted in the same change in energy stores even when it was not associated with sleep deprivation, suggesting that the changes are caused by stress rather than sleep loss.
Khayat et al. [ 23] showed that relatively low-frequency mechanical stimulation (0.01 Hz) could inhibit adipogenic differentiation of C3H10T1/2 mouse MSCs, even in a potent adipogenic differentiation medium.
We hypothesized that relatively low frequency mechanical stimulation (0.01 Hz) can inhibit adipogenic differentiation of C3H10T1/2 mouse mesenchymal stem cells, even in a potent adipogenic differentiation medium.
Indeed, any mechanoreceptor, even though best adapted to respond to some other form of mechanical stimulation, will respond to vibrations within some region of the sound frequency range if the vibrations have a sufficiently high level of intensity.
For example, the cough reflex can be suppressed easily, and even the gag reflex (the movements of incipient vomiting resulting from mechanical stimulation of the wall of the pharynx) can be suppressed with training.
Thus, an even greater enhancement of invasion occurs in the response to applied mechanical stimulation when the cells began in a three-dimensional environment.
