Abstract
Lipids are critical for the structure, signaling, and metabolism of the central nervous system (CNS), yet their roles during human brain development remain underexplored due to limited tissue availability. X-linked adrenoleukodystrophy (ALD), a peroxisomal disorder caused by ABCD1 mutations, disrupts very long-chain fatty acid (VLCFA) degradation, leading to axonal degeneration and demyelination. To investigate lipid dynamics in CNS development and ALD pathogenesis, we generated human induced pluripotent stem cell (hiPSC)-derived cortical and spinal cord organoids and performed lipidomics over 200 days. Lipidomic analysis revealed a dynamic lipidome, with changes in lipid abundance, saturation, and chain length reflecting neurodevelopment. ALD hiPSC-derived organoids exhibited significant lipid alterations over time, including elevated VLCFA levels and reductions in brain-relevant lipids, such as sulfatides and gangliosides, in cortical organoids. These findings provide a foundational resource for studying lipid dynamics in CNS development and emphasize the value of organoids for understanding ALD and other CNS diseases.
