鹿茸是雄鹿的第二性征，是由雄鹿头部额外脊处的骨膜组织所形成的，这部分骨膜被称为“生茸区骨膜”。生茸区骨膜具有巨大的生茸潜力，将生茸骨区膜移植到鹿体的其它部位，能诱导异位鹿茸的发生；一片直径约2cm的生茸区骨膜组能够在约60d的内再生出约10kg左右的鹿茸组织。研究发现，生茸区骨膜不同区域具有不同的生茸潜力，分别负责形成鹿茸的不同分枝和主干；生茸区骨膜细胞为干细胞。鹿茸干细胞的发现，为研究鹿茸生物学特性和揭示鹿茸完全再生机制开辟了一条新的通路。%Deer antler is the secondary sexuality for male ,and is initiation from the piece of periosteum overlying the lateral crest of prepubertal deer frontal bone ,known as antlerogenicperiosteum(AP) .AP has a strong ability of regeneration ,and can induce formation of ectopic deer antler when it was transplanted into elsewhere of deer body autologously .A piece of AP with about 2cm in diam can form about 10kg antler tissuesmass just in about 60days .Some studies found that the distribution of potential for deer antler information is regionalized in the AP ,and mainly resides in the anterior half and the medial half of the AP .Every subregion is responsible for different velvet antler branches and trunk ,respectively . Antlerogenic periosteal cells are stem cell ,which provides new approach to research underlying mechanism of deer antler formation and regener-ation .
