Different components of chicken egg-white extracts affect cell cycle and apoptosis / 中国组织工程研究

ABSTRACT

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