a–c SEM images (1), epifluorescence microscopy images (2), 2D (3) and 3D (4) confocal microscopy images of the patterned PCL fabric with EGFP-hMSC-TERT cells after 7 days (a, pattern 1.1; b, pattern 2.1; c, pattern 3.1). (Blue: nucleus, green: f-actin). d LDH activity measured from culture media collected 24 h after seeding EGFP-hMSC-TERT cells onto patterned PCL scaffolds (n = 6). e Cell proliferation on the patterned PCL fabric (n = 6). f, g Relative IL-6 (f) and TNF-α (g) levels in serum from healthy mice before PCL implantation and on days 3 and 7 after implantation. n = 3; *p ≤ 0.05; **p ≤ 0.005; ***p ≤ 0.001.
