The present invention relates to embryonic fibroblasts, which are cells isolated from avian eggs (egg), such as pluripotent stem cells (PSCs) or neural stem cells (NSCs), embryonic fibroblasts; Regarding the medium composition for cell proliferation, skin regeneration and wrinkle improvement containing FBs) conditional medium as an active ingredient, specifically, the egg (egg) cell conditioned medium is based on the use of animal serum. It can block contamination from the root, and further, it shows a proliferative effect of various cells including human stem cells and skin cells without the possibility of transmission by heterologous infectious substances by using supporting cells, and Since it shows a significant effect of skin regeneration or wrinkle improvement, the egg cell condition medium can be effectively used as a medium composition for cell proliferation and a cosmetic composition for skin regeneration or wrinkle improvement.
