Effect of Different Concentrations of Collagen, Ceramides, N-acetyl glucosamine, or Their Mixture on Enhancing the Proliferation of Keratinocytes, Fibroblasts and the Secretion of Collagen and/or the Expression of mRNA of Type I Collagen

本研究的目的在探討不同濃度之膠原蛋白、神經醯胺、N- 乙醯葡萄胺醣或其混合物對角質細胞、纖維母細胞增生的促進、膠原蛋白的分泌及/ 或膠原蛋白一型信息核糖核酸表現的影響。結果發現：對纖維母細胞增生的最適膠原蛋白、神經醯胺、N- 乙醯葡萄胺醣的濃度分別是49、2.0 與24.4 μg/mL；增生百分比分別是191%、170% 與223%（對照組為100%）。混合物含膠原蛋白、神經醯胺、N- 乙醯葡萄胺醣濃度分別為6.1、0.12 與6.1 μg/mL 對纖維母細胞的增生最好。對角質細胞增生的最適膠原蛋白、神經醯胺、N- 乙醯葡萄胺醣的濃度分別是0.76、0.001 與0.76 μg/mL；增生百分比分別是242%、203% 與230%（對照組為100%）。混合物含膠原蛋白、神經醯胺、N- 乙醯葡萄胺醣濃度分別為0.38、0.008 與0.38 μg/mL 對角質細胞的增生最好。對纖維母細胞膠原蛋白一型信息核糖核酸表現的最適膠原蛋白、神經醯胺、N- 乙醯葡萄胺醣的濃度分別是6.1、0.49 與6.1 μg/mL；膠原蛋白一型信息核糖核酸表現的百分比分別是152%、160% 與220%（對照組為100%）。混合物（含膠原蛋白、神經醯胺、N- 乙醯葡萄胺醣濃度分別為0.76、0.015 與0.76 μg/mL）對膠原蛋一型信息核糖核酸表現的百分比分為180%。

The objectives of the study are to survey the effects of different concentrations of collagen, ceramides, N-acetyl glucosamine (NAG), or their mixture on the proliferation of keratinocytes, fibroblasts and on the secretion of collagen and/or the expression of mRNA of type I collagen. The optimal concentrations that facilitated the proliferation of fibroblasts were 49, 2.0, and 24.4 μg/mL, respectively for collagen, ceramides, and NAG. The proliferation percentages were 191%, 170%, and 223%, respectively at the same order in compare to the control. The concentration of the mixture containing 6.1, 0.12 and 6.1 μg/mL, respectively of collagen, ceramides, and NAG facilitated the proliferation of fibroblasts. The optimal concentrations that had highest keratinocytes proliferation were 0.76, 0.001, and 0.76 μg/mL, respectively for collagen, ceramides, and NAG. The proliferation percentages were 242%, 203% and 230%, respectively at the same order in compare to the control. The optimal concentration that effects the highest keratinocytes proliferation by the mixture were 0.38, 0.008 and 0.38 μg/mL for collagen, ceramides and NAG, respectively. The concentrations for fibroblasts to express higher amount of type I collagen mRNA were 6.1, 0.49, and 6.1 μg/mL, respectively for collagen, ceramides, and NAG. The expression levels of type I collagen mRNA were 152%, 160% and 220%, respectively at the same order in compare to the control. However, the expressions of type I collagen mRNA were 180% in compare to the control at the concentration of mixture containing 0.76, 0.015 and 0.76 μg/mL, respectively of collagen, ceramides, and NAG.
