This study lacks evidence to support the link between proliferating cells and neurogenesis, the role of multipolar nestin(+) astrocytes as progenitors, and the identity of mature-looking doublecortin+ neurons as adult-born. The histology-marker expression observed differs from species with well-documented adult hippocampal neurogenesis.
Terreros-Roncal et al. investigated the impacts of human neurodegeneration on immunostainings assumed to be associated with neurogenesis. However, the study provides no evidence that putative proliferating cells are linked to neurogenesis, that multipolar nestin(+) astrocytes are progenitors, or that mature-looking doublecortin+ neurons are adult-born. Their histology-marker expression differs from what is observed in species where adult hippocampal neurogenesis is well documented.
