角柄

进一步研究发现，鹿茸再生是从角柄上发生的，是基于干细胞的过程，该过程取决于角柄远端骨膜干细胞受到周期性的激活。

Further studies showed that deer antler regeneration is taking place from pedicle periosteum , and it is based on stem cell regeneration process , which depends on the activation of the stem cell on the distal of pedicle periosteum periodicity .
