From: The assessment of xenogeneic bone immunotoxicity and risk management study
Inflammatory factors had no change after xenogeneic bone implantation. Xenogeneic bone being (bone 1) was implanted into Balb/c mice, TNF-α (a) and IL-6 (b) levels were measure using ELISAs and muscle ALP activities (c) in the site of implantation are quantified by colorimetric assay on days 7, 14 and 28. Statistical significance is defined as **p < 0.01 and *p < 0.05 compared with control
