Figure 1: Culture and isolation of human adipose-derived cells. Human adipose-derived cells were cultured in media (DMEM containing 10% FBS) for 7 days after isolation by chopping or collagenase treatment. A) Image of human adipose-derived cells. B) For the relative cell of isolated cells, cells isolated by collagenase treatment was set as 100%. **, p-value of less than 0.01. Scale bar = 40×, 100 μm.
