Footnotes: Pref1 is a common marker for brown, beige, and white preadipocytes121. Wt1 is a specific marker of visceral white adipocyte progenitors in the mesothelium122. Brown fat-selective (vs. beige fat) markers include: Lxh8, Zic1, Eva1, Pdk4 and Epstl111, 12, 60. Beige fat-selective markers include: Tbx1, Cited1, Shox2, Cd137, TMEM26, PAT2, P2RX511, 12, 37, 60, 61. CD29 is a recently identified marker for isolation of human preadipocytes123. Cell surface markers are labeled in blue.
