BV/TV indicates the portion of mineralized tissue and Conn.D indicates the degree of trabecular branching, while Tb.Th, Tb.Sp, and Tb.N provide detailed mircostructure parameters.
Femur neck is composed of more cortical bone whereas lumbar spine is composed of more trabecular bone (27).
MicroCT analysis revealed that male Nur77 KO mice had a low bone mass compared to WT male littermate controls, illustrated by a 36% lower bone volume/tissue volume ratio (BV/TV), 19% less bone surface (BS), 8% greater bone volume/bone surface ratio (BV/BS), 14% less trabecular number (Tb.N), 8% less trabecular thickness (Tb.Th), and 19% more trabecular separation (Tb.Sp).
The mean trabecular branch angle becomes more horizontal.
Larger FD values represent a more complex branching pattern.
Irregularly branched some branches far more branched.
Each shrub had four branches and each branch had more branches.
Their branching patterns showed that H. rhamnoides tended to expand horizontally, with more, shorter, thinner branches and a larger branch angle, whereas C. intermedia tended to grow perpendicularly with fewer, longer, thicker branches and a smaller branch angle.
Given these data, cortactin dissociates from branches much more rapidly than branches disassemble.
In comparison, control mice exhibited a severely reduced and more separated trabecular bone network, similar to that of Id1−/− mice.
