The authors find that distinct radial glia subtypes generate and support midbrain dopaminergic neurons, revealing specialized function and lineage relationships among the diverse cell types that shape dopamine neuron development.

The role of normally silenced transposable elements (TEs) in tumorigenesis remains unclear. Here, the authors show that increased expression of TEs in both patients and mice with colitis or by DNA hypomethylating drugs elicits a viral mimicry response that suppresses tumorigenesis. This viral mimicry response inhibits the stemness of cancer initiating cells in a cell autonomous manner.
