| Popis: | Human placenta-derived mesenchymal stem cells (hPMSCs) represent a promising source of stem cells. The application of hPMSCs in cartilage tissue engineering, however, was less reported. In this study, hPMSCs were grown in a three-dimensional (3D) environment for cartilage tissue formation in vitro. To select proper scaffolds for 3D culture of mesenchymal stem cells (MSCs), rat adipose-derived MSCs were initially employed to optimize the composition and condition of the 3D environment. The suitability of a poly(D,L-lactide-co-glycolide) (PLGA) precision scaffold previously developed for seeding and culture of primary chondrocytes was tested for MSCs. It was established that MSCs had to be embedded in alginate gel before seeded in the PLGA precision scaffold for cartilage-like tissue formation. The inclusion of nano-sized calcium-deficient hydroxyapatite (nCDHA) and/or a recombinant protein containing arginine-glycine-aspartate (RGD) into the alginate gel enhanced the chondrogenesis for both rat adipose-derived MSCs and hPMSCs. The amount of extracellular matrix such as glycosaminoglycan and type II collagen accumulated during a period of 21 days was found to be the greatest for hPMSCs embedded in the alginate/nCDHA/RGD gel and injected and cultivated in the precision scaffold. Also, histological analyses revealed the lacunae formation and extracellular matrix production from the seeded hPMSCs. Comparing human bone marrow-derived MSCs (hBMSCs) and hPMSCs grown in the previous composite scaffolds, the secretion of glycosaminoglycan was twice as higher for hPMSCs as that for hBMSCs. It was concluded that the alginate/nCDHA/RGD mixed gel in the aforementioned system could provide a 3D environment for the chondrogenesis of hPMSCs, and the PLGA precision scaffold could provide the dimensional stability of the whole construct. This study also suggested that hPMSCs, when grown in a suitable scaffold, may be a good source of stem cells for building up the tissue-engineered cartilage. |
