| 摘 要： | 海绵动物具备很强的愈伤再生能力。荔枝海绵是海绵动物中比较特殊的类群，它有皮质层细胞（cortex）和领细胞层细胞（choanoderm）的初步分化。本文对荔枝海绵的形态结构进行观察，并通过切割的方法，有针对性地移除荔枝海绵的特定结构，观察其愈伤过程，以期了解海绵愈伤过程的主要变化及各部分在愈伤过程中的作用。结果发现，愈伤过程发生的主要变化为未受创部分的细胞向受创部分迁移导致的细胞重新排布；其身体结构中的领细胞层和皮质层对其生存愈伤是必要的，而骨针核心对其愈伤影响较小。

| Abstract: | Sponges of Porifera have powerful regeneration capacity. Among them, the genus Tethya is a special group, which has differentiation in cortex and choanoderm. In this paper, the morphology of Tethya sp., and its wound-healing process were studied by removing specific part of some tissues, to understand the transformation of Tethya sp. and the role of different tissues in the healing process. The results showed that the main transformation in the wound-healing process is the cell rearrangement resulted by the cell migration from the unwounded to the wounded part, the cortex and choanoderm are vital to the survival of Tethya; while the spicule center is less importance in the wound-healing process. |
