Table 1 Donor characteristics

From: Cytokine profiles in the joint depend on pathology, but are different between synovial fluid, cartilage tissue and cultured chondrocytes

  1. aOf four healthy donors, both tissue and nonexpanded chondrocytes were analysed; for all the other donors, either synovial fluid, tissue, nonexpanded or expanded cells were analysed.
