Proliferation and differentiation (fusion) of myogenic satellite cells isolated from Nicholas tom and hen turkeys at 3, 9, and 15 weeks of age and the response of a satellite cell clone to serum from these birds were examined. Responsiveness of satellite cells to culture conditions was proportional to donor age, and sex of bird had no effect on satellite cell proliferation. Fusion percentages were similar in all cultures. When a turkey satellite cell clone was exposed to serum from tom and hen turkeys at each age, an age-related decline in proliferation occurred with serum from hen but not from tom turkeys. Minimal cell fusion occurred in turkey serum and neither proliferation nor fusion was correlated with serum IGF-I levels. Cells derived from pectoralis major and anterior latissimus dorsi muscles of 15-week-old tom turkeys possessed similar proliferation and fusion properties in vitro. It appears that satellite cells retain a high proliferative activity throughout growth in turkeys, and the mitogenic properties of turkey serum may be evaluated using turkey satellite cells in culture.

UI	MeSH Term	Description	Entries
D007334	Insulin-Like Growth Factor I	A well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on GROWTH HORMONE. It is believed to be mainly active in adults in contrast to INSULIN-LIKE GROWTH FACTOR II, which is a major fetal growth factor.

D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
