Figure 4From: Millicurrent stimulation of human articular chondrocytes cultivated in a collagen type-I gel and of human osteochondral explants Real-time PCR analysis of matrix-specific genes. Real time PCR analysis of col-II (a), aggrecan (b), col-I (c) and interleukin-1β (d) gene expression. Data are given as relative gene expression of stimulated samples in relation to gene expression of untreated samples of the same patients, which were set as 1. B-actin gene expression was included as internal standard. Given are mean +/- SD. N = 10. P = 0.05.Back to article page
