The Role of Glucose, Serum, and Three-Dimensional Cell Culture on the Metabolism of Bone Marrow-Derived Mesenchymal Stem Cells

Table 2

Summary of three-dimensional metabolic ratios. There was no clear trend in the data. (a: significantly different from corresponding value in the 5.0 mg/mL group; b: significantly different from the 25.0 mM value within the same collagen group; 𝑃=.05).
