The effect of human serum albumin on blastocyst lipid composition after 72 h in culture. A Representative images for each lipid dye. B Neutral lipid content. C Non-esterified fatty acid content. D Phospholipid content. E Triglyceride uptake. Data is expressed as mean ±SEM. Lipid composition is representative of n ≥ 20 per group with 4 replicate experiments per measure. Different superscript letters denote significance between treatments (P < 0.05). HSA, human serum albumin; a.u., arbitrary units
