ABSTRACT:
A process of extracting and purifying a bone protein capable of stimulating chondrogenic expression in undifferentiated cells in culture. The purification process is monitored at various stages by bioassaying the bone protein for chondrogenic activity in embryonic limb bud mesenchymal cell cultures.
