Description
Technical Field
The invention relates to the field of biological experiment devices, in particular to a deerskin gripper.
Background
Cornu Cervi Pantotrichum is an accessory organ of male Cervidae, and starts to grow when entering adolescence. Research shows that the growth of the antler depends on the periosteum of the future antler growing area. Removing periosteum before cornu Cervi Pantotrichum occurs, and removing potential of cornu Cervi Pantotrichum in cornu Cervi Pantotrichum producing area; if the periosteum is transplanted to the subcutaneous part of other parts of deer body, the occurrence of ectopic deer antler can be induced. This periosteum is therefore called trichogenous periosteum (AP). The AP of a non-antler-producing area can induce the generation of at most two ectopic deer antlers after being transplanted under the skin. Further studies have shown that: AP to initiate deer antler initiation must interact with the overlying skin, where the cuticle of the deer skin is induced into a deer skin cuticle, which is mediated by hair follicle papilla cells in the dermis. If AP tissue is directly transplanted to the lower part of a hair follicle in the dermis under the condition of vitro, then each dermal small pocket with embedded AP tissue is completely cut off and transplanted to the head of an immunodeficiency mouse (a nude mouse), the AP tissue quantity of one part can induce the generation of 12 xenogenous deer antlers. This finding provides the possibility of studying the interaction between antler-producing tissues and the skin, isolating and identifying the interacting substances, and verifying whether a certain gene is related to the generation and regeneration of antler (the only organ of a mammal that can completely regenerate). In order to induce the growth of xenogenous deer antler by intradermal transplantation of AP tissue, a small pocket of deer skin dermis must be created using a scalpel ex vivo. However, the process of making a small pocket of deerskin's dermis is hardly completed without a holder capable of properly tightening deerskin. This is mainly because the deer skin is soft, thin (< 2 mm) and tough, and very difficult to cut.
