Scaffolds based on blends of type I collagen and PDLLA were investigated for material stability in cell culture conditions (37 {\\deg}C; 5% CO2) in which post-electrospinning glutaraldehyde crosslinking was also applied. The resulting wet-stable webs were cultured with bone marrow stromal cells (HBMSC) for five weeks.
