CD90 expression is enriched in scAT and scAT-derived cells compared to dnAT and dnAT-derived cells. (A–C) Paired adipose tissue samples derived from the deep neck (dn) and subcutaneous (sc) regions was obtained in a previous study [15]. The mRNA expression of CD90 was determined by RT-qPCR in (A) 8 independent adipose tissue stromal cells (ASC) samples, (B) 8 corresponding in vitro differentiated adipocyte samples, and (C) 15 independent whole tissue samples. TF2B expression was used to normalize the data. Data are displayed as mean ± SD. * p < 0.05, ** p < 0.01, Student’s paired t-test. (D,E) Paired adipose tissue samples were derived from the deep neck (dn) and subcutaneous (sc) regions of another 33 patients undergoing neck surgery. The mRNA expression of (D) UCP1 and (E) CD90 was determined by RT-qPCR. HPRT expression was used to normalize the data. Data are displayed as mean ± SD. * p < 0.05, ** p < 0.01, Student’s paired t-test.
