Neuron | 彭勃等人提出了验证胶质细胞转分化的基本原则,并证明NeuroD1不能介导小胶质细胞-神经元重编程

图2 In vivo microglia-specific lineage tracing does not support the microglia-to-neuron conversion.
图3 Lentivirus induces non-specific labeling in vivo, which may confound the microglia-to-neuron observation.
图4 Even under microglia depleted brain, the “microglia-converted neurons” are detected, reflecting a lentiviral leakage artifact.
