Table 3 Effect of the addition of empty microcarriers at seeding on cell density (number of cells per microcarrier and per cm2) as well as aggregate size (number of microcarriers per construct)

From: Critical attributes of human early mesenchymal stromal cell-laden microcarrier constructs for improved chondrogenic differentiation
