Table 2 Evaluation of scaffold cytotoxicity in vitro for each protocol

From: Preparation and characterization of small-diameter decellularized scaffolds for vascular tissue engineering in an animal model

Group OD value (mean ± SD) RGR (%) Level
Negative control 1.239 ± 0.04 100  
Group I 0.967 ± 0.02 78.05 1
Group II 1.093 ± 0.05 88.22 1
Group III 0.897 ± 0.03 72.40 2
Group IV 0.957 ± 0.04 77.24 1
Group V 0.747 ± 0.01 60.29 2
  1. Cytotoxicity evaluation: RGR: relative growth ratio; level 1: RGR = 75–99%, low cytotoxicity; level 2: RGR = 50–74%, medium cytotoxicity
  2. The evaluation standard was derived from the Biological evaluation of medical devicespart 5: test for in vitro cytotoxicity (GB/T 16886.5-2003/ISO 10993-5:1999, IDT)
