Table 2. Cell morphology on 3D PLLA substrates.

Days in culture	Neurite density	Neurite length	Soma section area	Soma section roundness
Day 2	11/16 = 0.7	10.9±3.2 µm (n = 11)#	90.0±22.3 µm2 (n = 16)#	0.81±0.05 (n = 16)#
Day 7	60/14 = 4.3	25.2±13.8 µm (n = 60)* #	144.5±56.9 µm2 (n = 14)*	0.64±0.15 (n = 14)* #

^*value was significantly different from that for Day 2 (p<0.05).

^#value was significantly different from that for 2D in Table 1.
