Comparison of M₂ muscarinic G protein–coupled receptor diffusion (D_lat) in mouse primary cardiomyocytes, mouse heart muscle slices (at 23°C and 37°C), zebrafish heart slices, and neuronal structures identified within the mouse heart slices

	Mouse cultured cardiomyocytes (23°C)	Mouse tissue slice (23°C)	Mouse tissue slice (37°C)	Mouse neuritis (23°C)	Zebrafish tissue slice (23°C)
D_lat ± SD (µm² ⋅ s⁻¹)	0.16 ± 0.04	0.62 ± 0.11	1.3 ± 0.2	0.4^a	0.7 ± 0.06
Trajectories (n)	3,812	3,260	6,741	1,882	2,208
Cells (n)	8	17	11	N/A	11

N/A, not available

The D_lat value stated here assumes free 2-D motion, whereby the gradient of the MSD-versus-dT plot is equal to 4D_lat. Please see Discussion section for further explanation.
