GAG and DNA content (mean + SD) and histological evaluation of human CLC micro-aggregates treated with basal culture medium (control), supplemented with 10 ng/mL TGF-β1, 1 μg/mL or 10 ng/mL canine Link-N (LN), or 0.5 μg/mL or 5 ng/mL canine short Link-N (sLN) for 28 days in hypoxia (5% O2). (a) GAG content, (b) DNA content, (c) GAG content (incorporation in the micro-aggregate) corrected for DNA content, (d) total amount of GAGs released in the culture medium, (e) representative histological images of the Safranin O/Fast Green staining and collagen type I and II immunohistochemistry. *: p < 0.05. n = 3 (in duplicates).
