Implication

In vitro study demonstrates troglitazone and lipid supplements enhance preadipocyte differentiation in bovine depots, indicating uniform adipogenic potential.

Key Points

To establish an optimized in vitro serum-free culture system for bovine preadipocytes and evaluate depot-specific differences in differentiation between subcutaneous and intramuscular tissues.
Isolated stromal-vascular cells from subcutaneous (n = 3) and intramuscular (n = 2) adipose depots of three steers.
Treated cells in serum-free medium with combinations of insulin (280 nM), serum lipids, octanoate, acetic acid, dexamethasone (0.25 µM), and troglitazone (1.25 to 60 µM), assessing differentiation via glycerol-3-phosphate dehydrogenase (GPDH) activity and morphology.
A culture medium containing 280 nM insulin, 20 µL/mL serum lipids, 40 µM troglitazone, and 0.25 µM dexamethasone markedly stimulated differentiation (P < 0.001), whereas omitting insulin or troglitazone reduced GPDH activity by 68% (P < 0.001).
Addition of 40 to 60 µM troglitazone enhanced differentiation relative to 0 µM troglitazone (P < 0.02) across both subcutaneous and intramuscular preadipocytes, with no significant differences observed between depots (P = 0.32).
