Adipose-Derived Stem Cell Differentiation to the Adipogenic Lineage

Begin by seeding a six well plate with 10, 000 adipose-derived stem cells per square centimeter. Once cells become 60 to 80%confluent add the differentiation medium. On day 12, wash the cells trice with PBS and incubate them with 500 microliters of 4%formalin for one hour at room temperature.

Once the cells are washed with distilled water, wash them with 60%isopropanol for five minutes and let them dry. Add 500 microliters of 0.5%oil red O staining dye diluted in 60%alcohol. After incubation at room temperature wash the wells twice with one milliliter of distilled water and observe the plate under an inverted microscope.

Adipose-derived stem cells differentiated towards the adipogenic lineage showing reduced cell size and rounded shape within 48 hours. After seven days, lipid vesicles were visible, which were positive for oil red staining 12 days after differentiation.
