Johnny Thunders once wrote, "You can't put your arms around a memory…" and the song continues, "don't try." Yet, when complex morphogenetic movements accompany differentiation, the cellular memory of signaling becomes essential. In this issue of Cell Stem Cell, Gunne-Braden et al. (2020) report a network wrapping its arms around the memory of BMP signaling, a phenomenon known as hysteresis.

细胞可以将其手臂放在记忆周围吗？

约翰尼·雷德斯（Johnny Thunders）曾经写道：“你不能将自己的手臂放在记忆中……”，而歌曲继续说道：“不要尝试。” 然而，当复杂的形态发生运动伴随分化时，信号的细胞记忆就变得至关重要。在本期《细胞干细胞》中，Gunne-Braden等人。（2020年）报道了一个网络，将其手臂缠绕在BMP信号的内存周围，这种现象称为磁滞现象。
