hASCs were seeded on a 12-well plate at a density of 2×10
5 cells/well and incubated overnight. Cells were cultured for 14 days in osteogenic differentiation medium including test solution, and the medium was exchanged twice with a fresh one after 5 and 10 days. Then, total RNA was isolated with an
RNeasy minikit (Bio-Rad) according to the manufacturer’s protocol. Then, cDNA was synthesized from extracted RNA using an
iScript advanced cDNA-synthesis kit (Bio-Rad). All primers used were produced by DNA Technology (Aarhus, Denmark). The total volume of each sample was 20 μL, and samples were analyzed in duplicate with a
MyCycler real-time PCR system (Bio-Rad). The thermocycling program consisted of an initial step of 3 minutes at 95°C and 40 cycles of 15 seconds at 95°C and an annealing/extension temperature of 60°C for 30 seconds. Sequences of the primer sets were:
Osteocalcin (
OCN) forward 5ʹ-GAG CCC CAG TCC CCT ACC C-3ʹ, reverse 5ʹ-GCC TCC TGA AAG CCG ATG TG-3ʹ
Osteopontin (
OPN) forward 5ʹ-TGA TGG CCG AGG TGA TAG TGT GGT-3ʹ, reverse 5ʹ-CCT GGG CAA CGG GGA TGG-3ʹ
Peptidylprolyl isomerase A (
PPIA) forward 5ʹ-TCC TGG CAT CTT GTC CAT G-3ʹ, reverse 5ʹ-CCA TCC AAC CAC TCA GTC TTG-3ʹ.
Fold-change gene-expression levels were recorded using the ΔΔCt method, in which the data were normalized with the expression level of PPIA.
