Figure 3. Summary of putative molecular markers of motoneuron subtypes.
Notes: (1) No expression of GFP in Hb9::GFP mice despite the expression of Hb9 in ɣMNs during development [31]. (2) Expression of Chodl is restricted to the largest FR MUs, see [22] and text for details. (3) True only in rodents. SK3 is expressed in all αMN subtypes in cats. (4) expression is restricted postnatally only: signal is present at P0 but disappears at P14. (5) Several authors seem to disagree on this point, see text for details.
