Figure 5From: TGFβ signaling in the brain increases with aging and signals to astrocytes and innate immune cells in the weeks after strokeCo-localization of pSmad2 with neurons and oligodendrocytes after stroke. A.) Both before and after stroke 100% of neurons in the cortex are co-localized with pSmad2 in young and old mice. B.) Both before and after stroke ~70% of oligodendrocytes in the cortex are co-localized with pSmad2 in young and old mice.Back to article page
