Comparison of chondrogenesis in apple biomaterials Vs alginate microspheres. Chondrogenic and hypertrophic markers expression in perichondrial cells were compared after seeding into apple biomaterials or alginate beads 14 days of culture in normoxic conditions. mRNA expression of relevant genes was calculated using 3 housekeeping genes and normalized to alginate condition (n = 3, *: p˂0.05, **: P˂0.01, ***: P˂0.001)
