Abstract

Cigarette smoke is a risk factor not only for emphysema but also for other disorders characterized by deficient tissue repair, including osteoporosis. We hypothesized, therefore, that smoke might directly impair bone cell repair processes. To evaluate this, bone marrow osteoprogenitor cells were isolated from normal subjects and cultured in monolayer and in three-dimensional type I collagen gel culture. Human osteoprogenitor cells could be induced to differentiate toward osteoblast-like cells in both culture conditions by osteogenic supplements. Under both culture conditions, cigarette smoke extract (CSE) inhibited the proliferation of osteoprogenitor cells in a concentration-dependent manner. CSE also inhibited differentiation of osteoprogenitor cells toward osteoblast-like cells as assayed by alkaline phosphatase activity and calcium incorporation into cell layer. Cells in monolayer culture were more sensitive to the effect of smoke than cells in three-dimensional gel culture. Similar results were obtained with osteoblast-like cells derived from osteosarcomas. This study, therefore, demonstrates that cigarette smoke may affect bone progenitor cells directly and in this manner may contribute to the development of osteoporosis.
