Abstract

Sponges (Porifera) are lower metazoans whose organization is characterized by a high plasticity of anatomical and cellular structures. One of the manifestations of this plasticity is the ability of sponge cells to reaggregate after dissociation of tissues. This review brings together the available data on the reaggregation of sponge cells that have been obtained to date since the beginning of the 20th century. It considers the behavior of dissociated cells in suspension, the mechanisms and factors involved in reaggregation, and the rate and stages of this process in different representatives of this phylum. In addition, this review provides information about the histological structure of multicellular aggregates formed during reaggregation of cells and the regenerative morphogenetic processes leading to the formation of normal sponges from these multicellular aggregates.

[海绵细胞再聚集:过程的机制和动力学]。
海绵(Porifera)是低等后生动物,其组织的特点是解剖和细胞结构的高度可塑性。这种可塑性的表现之一是海绵细胞在组织分离后重新聚集的能力。这篇综述汇集了自20世纪初以来获得的关于海绵细胞再聚集的现有数据。它考虑了悬浮中游离细胞的行为,参与重新聚集的机制和因素,以及这一过程在该门不同代表中的速率和阶段。此外,本综述还提供了在细胞重新聚集过程中形成的多细胞聚集体的组织学结构以及这些多细胞聚集体形成正常海绵的再生形态发生过程的信息。
