Reversal Cells (IMAGE) Elsevier Health Sciences Caption Reversal cells actually cover more than 80 percent of the resorbed bone surfaces. Using histomorphometry and immunohistochemistry on human bone biopsies, researchers found that the reversal cells colonizing the resorbed bone surfaces are immature osteoblastic cells which gradually mature into bone forming osteoblasts during the reversal phase, and prepare the bone surface for bone formation.
