Although senescent cells can no longer replicate, they remain metabolically active and commonly adopt an immunogenic phenotype consisting of a pro-inflammatory secretome, the up-regulation of immune ligands, a pro-survival response, promiscuous gene expression (pGE), and stain positive for senescence-associated β-galactosidase activity by wiki , doi:10.1146/annurev-physiol-030212-183653
所以衰老細胞只是不複製,但各項代謝機能還是繼續進行,甚至可以抑癌,傷口修復等功用
