Increase of MOMA-2-positive microglia with age. (A) Comparison of the number of MOMA-2-positive cells in cortex of MPS IIIB (−) and wild-type control (+) mice at 0.5, 1, 3, and 6 months. Each bar represents the number of MOMA-2-positive cells in a low-power field of the cortex of one mouse. (B) Comparison of density of MOMA-2-positive cells in a low-power field in the cortex of MPS I and MPS IIIB mice of different ages; each bar represents one mouse, with SD derived from counting cells in three low-power fields.
