Abstract:

BACKGROUND: If an extract can prolong the S phase and reduce the percentage of apoptosis after co-culture with cells, it is proved that the extract is able to promote cell proliferation.
OBJECTIVE: To prove the effects of chicken egg-white extracts with different components on the proliferation, cell cycle and apoptosis of 293T cells.
METHODS: An ultrafiltration unit was used to separate chicken egg-white extracts into different components that were > 10 ku, < 10 ku, > 3 ku and < 3 ku to co-culture with cells for 3 days. Then, cell proliferation, cell cycle and cell apoptosis were detected.
RESULTS AND CONCLUSION: Chicken egg-white extract components of < 10 ku and < 3 ku could promote cell proliferation, increase the percentage of S-phase cells and reduce the percentage of apoptosis. In conclusion, chicken egg-white extract components that are < 10 ku and < 3 ku can promote cell proliferation, as well as increase the percentage of S-phase cells and reduce apoptosis percentage.
