ABSTRACT
<p><b>OBJECTIVE</b>To explore the chondrogenetic effect of induce media containing different concentrations of fetal bovine serum (FBS) on BMSCs differentiation in vitro and provide technical parameters for cartilage engineering in vitro.</p><p><b>METHODS</b>Passage 2 BMSCs of swine were seeded at the density of 5 x 10(7) cells/cm3 to disc-shaped PGA scaffolds with a diameter of 5mm and a thickness of 2mm. After 7days, the scaffolds were induced in media with TGF-beta1, IGF-I, dexamethasone, and different concentrations of FBS 0% in A group, 5% in B group, and 10% in C group. Specimens were collected after 8 weeks for gross observation, size evaluation, wet weight, glycosaminoglycan (GAG) content, histology assessment, and immunohistology of type II collagen.</p><p><b>RESULTS</b>The compound of C group showed china-white color, hard and fine texture, no obvious change in size and shape, typical lacuna structures, cartilage specific ECM, and significantly higher wet weight and GAG content. The compound of B group showed reduced size, fewer lacuna structures and some cartilage specific ECM. And the compound of A group showed greatly reduced size, soft and loose texture, and no typical lacuna structure or cartilage specific ECM.</p><p><b>CONCLUSIONS</b>FBS was indispensable to chondrogenetic media for in-vitro tissue engineering of cartilage with BMSCs.</p>
