Aβ affects dendritic spine and filopodia turn-over

	CHO CM	7PA2 CM

% new spines	3.2 ± 1.1	0.2 ± 0.2^**
% spine loss	1.5 ± 0.5	30 ± 5.9^**
% filopodia outgrowth	3.4 ± 0.7	34 ± 2.9^***
filopodia half-life (min)	4.7 ± 0.7	222 ± 30^**

^**

p < 0.01, and

^***

p < 0.001 indicate values significantly different using Student’s t-test. Percentages were calculated over a period of 10.8 ± 4.5 hrs (CHO CM) and 13 ± 4.3 hrs (7PA2 CM). no. of filopodia used to measure filopodia half life: CHO CM=12; 7PA2 CM= 79. no. of dendritic regions used to calculate percentages: CHO CM=8 (no. of cells 6); 7PA2 CM=10 (no. of cells=8).
