MTT a,c and Live/Dead b,d assays from both direct a,b and indirect c,d cell culture methods at day 10. Significant differences: MTT assay (direct contact): *P = 0.0004, difference between control group and uncoated- or polydopamine coated-PDMS bioscaffolds. #P= 0.002, difference between uncoated- and polydopamine coated-PDMS bioscaffolds. MTT assay (indirect contact): *P = 0.0000004, difference between control group and uncoated- or polydopamine coated-PDMS bioscaffolds. #P = 0.00003, difference between uncoated- and polydopamine coated-PDMS bioscaffolds. Live/Dead assay (direct contact): *P = 0.0001, difference between control group and uncoated- or polydopamine coated-PDMS bioscaffolds. #P = 0.04, difference between uncoated- and polydopamine coated-PDMS bioscaffolds. Live/Dead assay (indirect contact): *P = 0.0002, difference between control group and uncoated- or polydopamine coated-PDMS bioscaffolds. #P = 0.03, difference between uncoated- and polydopamine coated-PDMS bioscaffolds.
