Cascarilla Postdoctoral Fellowship in Stem Cell Research (L.R). NIH DP1OD003930 (T.M.); the ALS Association (M.A.C.); and The ALS Therapy Alliance (S.O.). We thank Amy MacDermott for introducing calcium-imaging approaches into our work and Kevin Eggan for open sharing of reagents and ideas throughout this study. We are grateful to F.P. Di Giorgio for the HUES3 HB9 reporter line; Susan Brenner-Morton and Thomas M. Jessell for graciously providing ISL1, HB9, RALDH2, and FOXP1 antibodies and motor neuron expertise; Lee Rubin for the human Smo agonist; David J. Kalher and Mathew Darwin-Zimmer (NYSCF) for help with FACS; R.M. Myers and F. Pauli, for performing RNA sequencing; and OB/GYN staff and the anonymous donors for tissue samples. We benefited from many helpful discussions with members of the Project A.L.S.; Wichterle, Henderson, and Eggan laboratories; and unwavering support from Valerie and Meredith Estess (Project A.L.S.).
