Expression of (a) genes associated with meniscus extracellular matrix production and (b) meniscus progenitor phenotype as measured by quantitative real-time PCR and (c) progenitor marker expression measured using flow-cytometry after monolayer expansion. n = 5 donors per group per condition. ACAN, aggrecan; COL1A1, collagen type I alpha 1 chain; CDK1, Cyclin-dependent kinase 1; DNER, Delta and Notch-like epidermal growth factor-related receptor; FN-prog, fibronectin selected cells; MCAM, Melanoma cell adhesion molecule; Men, total meniscus population * p < 0.05; ref, reference category.
