From: Normal proliferation and differentiation of Hoxc-8 transgenic chondrocytes in vitro
Micromass cultures of primary rib chondrocytes. Morphology of micromass cultures was examined at day 3 (A-D) and day 15 (E-H) by light microscopy of paraffin-embedded sections stained with hematoxylin and eosin (A and E), Alcian blue (B and F), Collagen II (C, G), and Collagen X (D, H). Cell proliferation was assessed by BrdU uptake as detected by immunohistochemistry on days 3 (I), 6 (J), 8 (K) and day 15 (L), respectively.
