Furthermore, OCN staining confirmed an increase in osteogenesis in PTD + TBI rats (Fig. 1f, g), whereas no significant change in the number of osteoclasts tartrate-resistant acid phosphatase (TRAP) positive cells and osteoclast surface per bone surface between the two groups (Supplementary Fig. 3e–g). The gene discussed is BGLAP; the disease is Bjornstad syndrome.
