Abstract:
In this study, cells from the stromal vascular fraction of human subcutaneous tissues were induced to differentiate toward adipose cells in vitro for 2 weeks. During adipogenic differentiation, we followed the chronological changes in their morphology with Coherent anti‐Stokes Raman scattering (CARS) microscopy and checked the PPAR‐γ and UCP‐1 expression with RT‐PCR. On day 4 after inducing adipogenic differentiation, CARS imaging showed multiple small lipid droplets (LD) distributed peripherally along the cellular membrane. PPAR‐γ began to express at this time and increased until day 14 at a steady rate. On day 7, the cells appeared as brown adipocytes with numerous small LD throughout the cytoplasm, and the mRNA level of UCP‐1 rose abruptly by 6‐ to 7‐fold. After an additional 7 days, CARS imaging showed the development of a large LD, which is characteristic of white adipocytes, and the mRNA level of UCP‐1 slumped significantly. These results demonstrate the possibility that ADSC pass through a brown adipocyte‐like stage while differentiating into white adipocytes.
