Many amphibians can regenerate limbs, even in adulthood. If a limb is amputated, the stump generates a blastema that makes a complete, new limb in a process similar to developmental morphogenesis. The blastema is thought to inherit its limb-patterning properties from cells in the stump, and it retains the information despite changes in morphology, gene expression, and differentiation states required...
GABAergic Purkinje cells (PCs) provide the primary output from the cerebellar cortex, which controls movement and posture. Although the mechanisms of PC differentiation have been well studied, the precise origin and initial specification mechanism of PCs remain to be clarified. Here, we identified a cerebellar and spinal cord GABAergic progenitor-selective cell surface marker, Neph3, which is a direct...
