Quantitative analysis of cellular proliferation and activity of hBMSCs seeded on 3D-printed PCL and PLATMC at 3, 7 and 21 days, represented as column charts showing: a cell proliferation characterized by DNA quantification using Picogreen assay; b apoptotic tendency characterized by LDH activity assay; c cell metabolic activity characterized by alamarBlue assay; and d ALP activity. Note the higher proliferation rate and viability on PLATMC, while less ALP activity compared to PCL. Statistical significance between each time point and the previous time point in the same group is marked with hash symbol (#), while significance between the groups is marked with Asterisks (*) at p < 0.05; * p > 0.0332, ** p > 0.0021, *** p > 0.0002, **** p < 0.0001
