Programmed cell death

特許 権利維持 Programmed cell-death (or PCD) is death of a cell in any form, mediated by an intracellular program.[1][2] PCD is carried out in a regulated process, which usually confers advantage during an organism's life-cycle. For example, the differentiation of fingers and toes in a developing human embryo occurs because cells between the fingers apoptose; the result is that the digits are separate. PCD serves fundamental functions during both plant and metazoa (multicellular animals) tissue development.
