PD mice that received LMX1A+EN1+, CLSTN2-, or PTPRO-sorted progenitors or unsorted progenitors gradually recovered over time from the amphetamine-induced rotation behavior (Figure 10H and Supplemental Figure 7L), whereas those that received only artificial cerebrospinal fluid (aCSF) did not (Figure 10H). The gene discussed is LMX1A; the disease is Parkinson disease.
