(IMAGE) Tokyo Medical and Dental University Caption (A) We analyzed the expression of Mkx and Scx in the rat PDL and found that Mkx and Scx expression is observed in different cells in PDL. (B) While Scx-espressing cell population (Scx, red box) more abundant expression of collagen (Col1a1 and Col3a1), Mkx-expressing cell population (Mkx, blue box) exhibited higher expression of genes involved in the synthesis of oxytalan fibers (Matn4) and extracellular matrix (Vcan).
