Fig 1 — Multipotentiality of HDPCs isolated from human dental pulp. Isolated HDPCs were differentiated into chondrocytes (A, B, C) and adipocytes (D, E) under appropriate conditions described in Materials and Methods. (A) Differentiated chondrocytes were stained with alcian blue, and (B) the expression of aggrecan (a chondrocyte marker) was visualized by immunostaining. (C) Cell morphology of the differentiated chondrocyte was visualized by HE staining. Hypertrophic cells were observed at the peripheral area of the cell pellet. (D) Cell morphology of the differentiated adipocyte and (E) its high magnified image. Lipid accumulation was observed in the differentiated cells. Bars: 50 μm scale.
