L-929 mouse fibroblasts
co-cultured with various EGC membranes were used to
determine the cytotoxicity of the membranes. EGC membranes
with 31.2 and 46.8 mg/ml of CA extract were
separately and continuously electrospun for 1, 4, and
14 h. Neat GEL/PVA membranes were used as the control.
The CA concentration in each EGC membrane
depended on the duration of the fabrication. The EGC
membranes that were treated with 31.2 mg/ml of CA
extract and electrospun for 4 h produced the optimal effect
on cell proliferation. The cell proliferation increased
by up to 93% when compared with that observed for the
neat GEL/PVA membranes (Figure 6).
