Previously undescribed members of oligodendrocyte differentiation module M15 were identified that exhibited differential expression during oligodendrocyte differentiation, day 4 versus day 0 in differentiating conditions (log₂ FC > 1, q value < 0.01). “X” indicates significant overlap between modules by FDR-corrected hypergeometric testing.
