ASCs at cellular passage 4. N-ASCs were seeded on a glass with a diameter of 24
mm in six-well plates in triplicates with complete medium. The wells were
incubated at 37°C and 5% of CO2. After 24 h, cells were fixed with 4%
buffered formalin for 1 h at 4°C in the dark, washed three times with sterile
PBS 1×, and incubated with SEEA3 (FITC conjugate, 1:200 dilution) and CD105 (APC
conjugate, 1:200 dilution) antibodies in the dark at 4°C for 30 min. At the end
of the incubation with the antibodies, the glasses were washed with PBS, and
mounting medium containing DAPI was added. The slices were imaged with an
Olympus BX-51 microscope (Olympus) equipped with a digital camera (DKY-F58 CCD
JVC) at 60× objective. Images were prepared using Las-X software.
