For adipogenic differentiation, ADSCs and LDSCs at passages 2, 4, and 6 were seeded in 6-well plates (8 × 103 cells/cm2) and cultured in H-DMEM supplemented with 10% FBS and 1% antibiotic-antimycotic solution until confluency. The medium was changed to canine adipocyte differentiation medium (Cell Applications) [13 (link)]. The medium was changed twice weekly. Adipogenesis was analyzed by Oil Red O staining after 21 days.
Positive-stained areas were measured with ImageJ. Four fields were randomly selected from culture dishes divided equally into four regions.
