Effect of Wnt3a-HA treatment on neurogenesis 28 days after injury.

<p>A. A co-localized BrdU/NeuN cell is shown in the striatum. B–D. Wnt3a-HA injection into the striatum led to a significant increase in the number of newborn neurons in the striatum (<i>p</i><0.01). Treatment with Wnt3a-HA into the SVZ did not change the number of newborn neurons in the striatum. Number of newborn neurons (B), proliferating progenitors (C) and NeuN⁺/BrdU⁺ (D) cells in the striatum and SVZ.
