Figure 3From: Three-dimensional culture of human meniscal cells: Extracellular matrix and proteoglycan productionHistologic images of human meniscus cells cultured under control conditions in the 3D collagen sponge. A. Arrows show good attachment of cells to the sponge surface. B. * denotes concentration of ECM. C. Margin shows a tight layer of cells along the perimeter of the sponge. (Paraffin embedded toluidine-blue stained specimens; for all images, bar = 50 μm).Back to article page
