Then the caprine fetal fibroblast cells were transfected with p6.5hLF-EGFP by LipofectamineTM-2000 and selected by G418 for 3 to 4 weeks. The G418 resistant transfectants were identified by PCR and EGFP detection. The results indicated that the transgene was stably integrated into the open region of the chromatin of G418 resistant fibroblast cells.

Fibroblast growth factor 21（FGF21）is a novel fatty metabolic regulator. FGF21 mRNA is most abundantly expressed in liver. FGF21 contribute to fat metabolism, as well as ketogenic responses in liver,and it can promote the uptake of glucose, promote insulin secretion, delaying the development of tumors and other function.

成纤维细胞生长因子21（fibroblast growth factor 21，FGF21）是一种主要的脂肪代谢调节因子，主要在肝脏中表达；FGF21有助于肝脏的脂肪代谢以及生酮反应，可以促进脂肪细胞摄取葡萄糖，促进胰岛素分泌，延缓肿瘤的发展等功能。
