Cell viability of seeded HSF 1184 (cell 2 × 105/cm2) using MTT assay. MTT assay was performed after 72 h treatment of different concentration of scaffolds 0.5, 1.5, 2.5, and 5.0 mg/mL for each sample: (a) PCL/chitosan scaffolds, (b) nHA/PCL/chitosan scaffolds, and (c) nHA/PCL/chitosan/tetracycline HCl scaffolds and control (cell without treatment). The treatment was carried out with 3 replicates (). The statistical significant analysis paired -test at was indicated () compared to control cells.
