Survival of embryonic motoneurons from wild-type,Gfra2−/−, andGfra1−/− mice in the presence of GDNF and NTN. A, Survival of motoneurons from wild-type (WT) andGfra2−/− E12.5 embryos in the presence of different concentrations of GDNF and NTN.B, Survival of motoneurons from wild-type (WT) andGfra1−/− E13.5 embryos in the presence of different concentrations of GDNF and NTN. Survival values (mean ± SEM; n = 3) are normalized for survival in basal medium [Neurobasal (NB) defined as 0%] and expressed for each region as percentage of the number of motoneurons that developed in 1 ng/ml BDNF (defined as 100%).
