“…This is similar to the morphological appearance of granulocytes present in B. glabrata (Cheng, 1975;Jeong and Heyneman, 1976) and in Oncomelania hupensis (Morona and Mingyi, 1989). Filopodia reflect the functional activity of the granulocytes, playing an external role in cellular defense (Tripp, 1970;Harris and Cheng, 1975;Sminia, 1981;Fryer and Bayne, 1996;Matricon-Gondran and Letocart, 1999), involvement in phagocytosis and encapsulation of foreign material (Cheng and Garrabrant, 1977) and wound healing (Sminia et al, 1973), all requiring cell movement. Fisher (1986) reported that granular cells were most responsive to bacteria and virus.…”

“…The latter process allows the internalisation of large volumes of Xuid and is common in mammalian phagocytes (Dharmawardhane et al, 2000). Despite the relative abundance of data on MP in various types of mammalian cells, few and scanty data are found in the literature concerning the occurrence of this process in non-mammalian vertebrates or invertebrates (Amyere et al, 2002;Matricon-Gondran and Letocart, 1999).…”

“…However, more recent studies describe three cell types based on size, ultrastructure and internal complexity. In B. glabrata , three haemocyte subpopulations have been described: large haemocytes (> 8µm), medium haemocytes (~8µm) and small haemocytes (5–6µm) [70]. Large haemocytes are characterized by an asymmetrical shape, small nucleus:cytoplasm ratio, cytoplasm with numerous mitochondria, dense particles of glycogen and prominent extensions.…”

“…Small haemocytes have a high nucleus:cytoplasm ratio, are organelle-rich, with few secretory granules. In terms of haemolymph proportions, the large and medium haemocytes are almost equally numerous while small haemocytes are comparatively fewer [70]. B. glabrata and B. tenagophila haemocytes have also been categorized into three (large, medium and small) categories based on flow cytometric analysis [71].…”

Haematopoiesis is a process that is responsible for generating sufficient numbers of blood cells in the circulation and in tissues. It is central to maintenance of homeostasis within an animal, and is critical for defense against infection. While haematopoiesis is common to all animals possessing a circulatory system, the specific mechanisms and ultimate products of haematopoietic events vary greatly. Our understanding of this process in non-vertebrate organisms is primarily derived from those species that serve as developmental and immunological models, with sparse investigations having been carried out in other organisms spanning the metazoa. As research into the regulation of immune and blood cell development advances, we have begun to gain insight into haematopoietic events in a wider array of animals, including the molluscs. What began in the early 1900’s as observational studies on the morphological characteristics of circulating immune cells has now advanced to mechanistic investigations of the cytokines, growth factors, receptors, signalling pathways, and patterns of gene expression that regulate molluscan haemocyte development. Emerging is a picture of an incredible diversity of developmental processes and outcomes that parallels the biological diversity observed within the different classes of the phylum Mollusca. However, our understanding of haematopoiesis in molluscs stems primarily from the three most-studied classes, the Gastropoda, Cephalopoda and Bivalvia. While these represent perhaps the molluscs of greatest economic and medical importance, the fact that our information is limited to only 3 of the 9 extant classes in the phylum highlights the need for further investigation in this area. In this review, we summarize the existing literature that defines haematopoiesis and its products in gastropods, cephalopods and bivalves.
