The presence of lining cells on surfaces of human trabecular bone.
Sixteen human trabecular bone biopsies were obtained from sites located in the ilium and in the area of the greater trochanter of the femur. Patients ranged from 19 to 85 years old and included men and women. All bone surfaces observed contained osteoid. Flat, branched fibroblastic-like cells were observed lining bone surfaces in all biopsy specimens. The presence of these cells was not dependent on age, sex, race, or disease state of the patient. Based on this study, we believe that the majority of human trabecular bone surfaces are covered with these thin lining cells.
