Abstract:
The promoting effects on cell proliferation of the 105K glycoprotein (105Kgp), purified from sera of chickens to which a Marek's disease (MD) lymphoblastoid cell line, MDCC-MSB1-41C (MSB1-41C), had been transplanted, were examined using culture cells from various sources. The MSB1-41C line as well as the other chicken lymphoblastoid cell lines examined were sensitive to the 105Kgp. The growth-promoting effects of 105Kgp showed a biphasic pattern depending upon the amount of 105Kgp added into the culture medium. These findings indicate that the 105Kgp may be a promoting factor for chicken growing cells, especially lymphoblastoid cell lines.
