Figure 1From: Supplementation with conjugated linoeic acid decreases pig back fat deposition by inducing adipocyte apoptosisTUNEL assay of apoptotic cells (200× magnification). Pig back fat cryosections were analyzed using a TdT-mediated dUTP nick end labeling (TUNEL) apoptosis detection kit (Beyotime, China) according to the manufacturer’s instructions. Typical apoptotic cells (brown spots) are emphasized with red rings in this figure. This clearly shows that the 2% CLA-fed pigs had more apoptotic fat cells.Back to article page
