HOXB7 and bFGF expression in 3D AT-MSC cultures treated with SF. a, b qRT-PCR analysis of HOXB7 (a) and bFGF (b) mRNA expression levels in 3D AT-MSC cultures 1 day after treatment with SF or maintenance medium (*p = 0.002 for HOXB7, unpaired two-tailed Student’s t test). Error bars, SD. (c) HOXB7 protein expression in 3D AT-MSC cultures by IHC. Analysis was performed 1 day after treatment with SF or maintenance medium. Photomicrographs were acquired using an Axio Imager M2 (Zeiss) with an EC Plan Neofluar ×40/0.75 objective
