Developmental profiles illustrating the appearance of brown adipocytes in interscapular brown adipose tissue (iBAT) initially at about 4 days before birth. Although the inguinal fat depot (ING) first appears at birth, but the visceral fat (VAT) not until ∼ 10 days of age, brown adipocytes appear in both depots between 15 and 30 days of age. The induction of brown adipocyte at 20 days of age is higher in A/J than C57Bl/6J (B6) mice and is induced in adult animals by adrenergic stimulation in A/J mice, but not B6 mice. This genetic difference in the induction of brown adipocytes among white fat depots is not found in iBAT. This figure has been modified from Xue et al.,39 courtesy of Nina Laidlaw.
