The distribution of S100-immunoreactive (ir) corpuscular endings was examined in the palate of wildtype and knockout mice for trkA, trkB or trkC. In wildtype mice, S100-ir corpuscular endings were abundant at the top of palatal rugae. The endings contained 2-4 parallel arrays of S100-ir neurites. The distribution of S100-ir nerve endings in trkA and trkC knockout mice was similar to that in wildtype mice; S100-ir corpuscular endings were abundant in palates of the mutant mice. In trkB knockout mice, the palate was devoid of corpuscular endings. An immunoelectron microscopic method indicated that S100-ir corpuscular endings were identical to Meissner corpuscles. The normal development of Meissner corpuscles is probably dependent on trkB but not trkA or trkC. (C) 2000 Lippincott Williams and Wilkins.
