Figure 1From: Induction of osteogenic markers in differentially treated cultures of embryonic stem cells Mi neral deposition at day 14 in differently treated embryonic stem cells (ESCs). Cells were exposed to (a) LIF (leukemia inhibitory factor), (b) without LIF, (c) DAG (dexamethasone, ascorbic acid and β-glycerophosphate) or (d) BMP-2. Shown are von Kossa stainings with arrows pointing to the deposition of calcium phosphate-containing minerals that stained in black.Back to article page
