2. Figure 1
Confocal scanning laser micrography with a double-labeling with anti-CK 20 and anti PGP 9.5 in the epidermal compartment after 15 days of co-culture. (a) Merkel cells (green) in contact with PGP 9.5+ nerve endings (red). Merkel cells are assembled around nerve ending and form a Merkel corpuscle. They are associated with nerve endings obtained by division from one axon. (b) Merkel cell (green) in contact of nerve fibers (red). An overlap area (yellow) shows the synapse-like structure.

3. Figure 2
Triggering of spontaneous activity in neurons after heat stimulation of co-cultured keratinocytes. The initial temperature was 22°C. The application of the heat stimulus is indicated by the arrows. Upper trace: control recording showing no spontaneous activity. Middle traces: initial response (start) after stimulation by 100μl of medium heated at 37°C showing a slow depolarizing current along with the triggering of some spontaneous spikes; after 10minutes, the slow current vanished, but some spikes still remained. Lower traces: response observed immediately after the application of 100μl of medium heated at 45°C corresponding to a larger depolarizing current and more numerous spikes. A second application (second arrow) enhances the current. After 10minutes, a spontaneous activity remained, somewhat more sustained that in the previous stimulation. Recordings were made from neurites by macro-patch technique, in cell-attached configuration.
