The effect of denervation of Merkel cells in cats

Neurosci Lett. 1977 Sep;5(6):327-32. doi: 10.1016/0304-3940(77)90108-2.


The morphology of Merkel cells in sinus hair follicles of the upper lip (vibrissae with a circular blood sinus), and in touch domes of the glabrous skin of the nose, was investigated in cats up to 12 weeks after resection of the infraorbital nerve. Even 12 weeks after denervation there was neither an ultrastructural alteration of Merkel cells nor a reduction of their number in sinus hair follicles. Also in touch domes the Merkel cells did not disappear.
