Amino Acid Uptake Limitations during Human Mesenchymal Stem Cell-Based Chondrogenesis.

ABSTRACT: A mino acids are the essential building blocks for collagen and proteoglycan, which are the main constituents for cartilage extracellular matrix (ECM). Synthesis of ECM proteins requires the uptake of various essential/nonessential amino acids. Analyzing amino acid metabolism during chondrogenesis can help to relate tissue quality to amino acid metabolism under different conditions. In our study, we studied amino acid uptake/secretion using human mesenchymal stem cell (hMSC)-based aggregate chondrogenesis in a serum-free induction medium with a defined chemical formulation. The initial glucose level and medium-change frequency were varied. Our results showed that essential amino acid uptake increased with time during hMSCs chondrogenesis for all initial glucose levels and medium-change fre
