Figure 2. Expression of osteogenic markers on RNA-level.

Figure 2

A) Semiquantitative polymerase chain reaction (PCR) of the osteogenic markers osteocalcin (246 bp) and alkaline phosphatase (238 bp) expressed in MSC on TCPS (d0) or cultured for 21 days in osteogenic induction medium (OIM) on TCPS, Resomer® LT706 and PCL. ß-Actin (400 bp), loading control: DNA marker (100 bp ladder) = 600 bp. Results of one representative experiment out of three are shown. B) Microarray-data of three independent experiments (n = 3) for osteocalcin, bone sialoprotein, Cbfa-1 and alkaline phosphatase expressed in MSC on TCPS (d0) or cultured for 21 days in OIM on TCPS, Resomer® LT706 and PCL.
