To compare the chondrogenic and proliferative effects of pooled human serum (HS) and fetal bovine serum (FBS) on tissue-engineered human nasal septal chondrocytes.
Human chondrocytes were expanded for one passage in monolayer in medium supplemented with 10% FBS, 2% HS, 10% HS, or 20% HS. Cells were then suspended in alginate beads for 3D culture for 2 weeks with 10% FBS, 2% HS, 10% HS, or 20% HS.
Monolayer cell yields were greater with HS than FBS. In alginate, cellular proliferation, glycosaminoglycan production per cell, and type II collagen were significantly higher with 10% HS compared to 10% FBS controls.
HS results in increased proliferation and production of cartilaginous extracellular matrix by tissue-engineered human nasal septal chondrocytes, compared to FBS controls.
Culture with human serum may facilitate creation of neocartilage constructs that more closely resemble native tissue.
比较人混合血清(HS)和胎牛血清(FBS)对组织工程化人鼻中隔软骨细胞的软骨生成和增殖作用。
人软骨细胞在补充有10% FBS、2% HS、10% HS或20% HS的培养基中单层扩增一代。然后将细胞悬浮于藻酸盐珠中,在含有10% FBS、2% HS、10% HS或20% HS的条件下进行三维培养2周。
HS培养的单层细胞产量高于FBS。在藻酸盐中,与10% FBS对照组相比,10% HS组的细胞增殖、每细胞糖胺聚糖产量和II型胶原蛋白含量显著更高。
与FBS对照组相比,HS可使组织工程化人鼻中隔软骨细胞的增殖增加,并促进软骨细胞外基质的产生。
用人血清培养可能有助于创建更接近天然组织的新软骨构建体。
