NPC1L1 and osteoporosis: Consistent with these findings, measurements of the bone volume‐to‐tissue volume ratio (BV/TV), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), and trabecular number (Tb.N) further confirmed that NPC1L1 knockdown progressively enhanced bone formation and delayed osteoporosis progression in OVX mice (Figure 3C–F).
