Effects of Dendrobium Polysaccharides on the Functions of Human Skin Fibroblasts and Expression of Matrix Metalloproteinase-2 under High-Glucose Conditions

Figure 1

Effects of high glucose concentration and PDC on the viability of the HSF cells. HSF cells were incubated at high glucose concentration (25 mmol/L) or PDC (100, 200, and 400 μg/mL) for 48 h. The MTT assay was used to detect the cell viability. All the data were expressed as (n = 3). , compared with the control group; , compared with the high-glucose group; , compared with the high-glucose + Dendrobium polysaccharide (100 μg/mL) group; , compared with the high-glucose + Dendrobium polysaccharide (200 μg/mL) group.
