I also noted that inserting a stem into the canal destroys the endosteum
, a thin layer of connective tissue filled with cortical capillaries that lines the medullary cavity.
Sindbis-group alphavirus replication in periosteum and endosteum
of long bones in adult mice.
Secondary bone healing in birds initially involves proliferation of fibroblasts surrounding the fracture site forming a "soft" fibrous callus, whereas osteogenic cells migrate from the periosteum and endosteum
and proliferate at the fracture site.
MSCs can be obtained from the umbilical cord, amniotic fluid, placenta, adipose tissue, joint synovium, synovial fluid, dental pulp, endosteum
, and periosteum [2-4, 6, 7].
Moreover, these cells become dormant as they can remain in cycling quiescence close to the endosteum
area in the BM.
Peripheral osteomas are caused by centrifugal growth of the periosteum and develop as masses attached to the cortical plates, whereas central osteomas arise centripetally from the endosteum
. (2,3,10) The extra skeletal soft tissue osteoma lies within a muscle.
Although resorption of the endosteum
advances in the later stages of life for both males and females, the simultaneous process of growth and bone apposition that is specific to males only, may explain the increased tibial morphometry in males (Ruff & Hayes, 1995).
Central ossifying fibromas arise from the endosteum
or the periodontal ligament adjacent to the root apex and causes expansion of the medullary cavity.

For example, a strong signal was found in the endosteum
of the scala tympani and basilar membrane (Figure 42), and its relative density was greatest in the basal turn.
Studies in animal models on related flaviviruses have shown the virus RNA in the synovial fluid, virus replication in the endosteum
and periosteum of the affected joints and antibody indicating an immune complex aetiology of the arthritides through complement activation (16).
It sustains high blood pressure to reach distant locations, usually terminating into capillaries present in the metaphysis and endosteum
. There is a central large vein that receives blood from capillaries present in various regions and drains deoxygenated blood and nutrient waste from bone .
