Hyaluronan concentration in the culture media of different cell types

Cell type	Hyaluronan production (ng/10,000 cells/24 hr)
Breast cancer cells (MCF-7, GFP transfected)	0.8 ± 0.5
Breast cancer cells (MCF-7, GFP-Has3 transfected)	136 ± 7
Arterial smooth muscle cells (RAA, rabbit)	21 ± 4
Chondrocytes (bovine patella)	44 ± 3
Mesothelial cells (LP-9, human)	115 ± 19
Tumor stromal fibroblasts (human)	305 ± 46

Means ± SD of three wells of MCF-7 cells; means ± SD of six wells in other cells. GFP, green fluorescent protein; RAA, rabbit vascular smooth muscle cells.
