Musculature of the stomach and small intestine of BALB/c and
Wsh/Wsh mice.
ICC were detected using immunofluorescence, showing TMEM16A immunoreactivity (green)
and c-Kit ACK4 immunoreactivity (red) in both BALB/c (A, C, E) and
Wsh/Wsh (B, D, F) mice. In
the fundus (A, B), ICC-IM were observed in the musculature only in BALB/c mice. In the
corpus (C, D), BALB/c mice have ICC-MY (arrows) and ICC-IM. Contrastingly,
Wsh/Wsh mice have only
ICC-MY (arrows) that were confirmed through TMEM16A immunoreactivity. In the small
intestine (E, F), BALB/c mice have ICC-DMP (arrowheads) and ICC-MY (arrows) with
TMEM16A (green) and c-Kit (red) immunoreactivities, whereas
Wsh/Wsh mice have TMEM16A
immunopositive ICC-DMP (arrowheads) in the circular muscle. c and l represent circular
and longitudinal muscle layers, respectively. Asterisks show myenteric layer. Bar: 50
