“…aegypti seems much like that described in Gerris (Moriber 1956) and Dyosophila (Cooper 1950, Clayton 1962, Yasuzumi et al 1958 while unlike that in the more closely related Sciara. In the latter, mitochondria form progressively larger spheres in the course of meiosis , and these persist through spermiogenesis and in the mature gamete (Doyle 1933) .…”

In male germ cells, the PAS reaction is considered specific only for Golgi material and acrosome (Moriber 1956, Clayton et al 1958, Kaye 1962, Bawa 1960; the absence of PAS staining in testicular cells of Aedes despite strong, simultaneous staining in other tissues thus argues against the presence of an acrosome or its precursors in this insect.…”

“…The acrosome of most flagellate spermatozoa is derived from a Golgi-like structure, the acroblast, which in turn arises from fusion of Golgi elements (dictyosomes) in the spermatocyte or spermatid (Bowen 1924, Doyle, 1933, Cooper 1950, Franzen 1965, Fawcett 1957, Moriber 1956, Bawa 1960, Kay 1962). These structures have been reported to be quite visible in living cells under phase contrast (Franzen 1956, Moriber 1956, Fawcett and Ito 1958, Clayton et al 1958, Bawa 1960, Clayton 1962, and their apparent absence in Aedes supports the view that an acrosome is not elaborated in this species. Cytochemical tests specific for DNA, RNA, polysaccharides and protein were attempted in efforts to better characterize substructures observed in living cells.…”

“…A constantly observed property of the early acrosome in spermatids large enough to permit the use of histochemical techniques for light microscopy (water striders, crayfish, house cricket, various mammals) is its strongly positive PAS reaction (POLLISTER, 1930;MORIBER, 1956;MOSES, 1961;YASUZUMI et al, 1961;KAYE, 1962;ONUMA and NISHIKAWA, 1963). The results (obtained with the three invertebrate materials were interpreted as indicating the presence of a considerable amount of polysaccharide.…”

The course of acrosomal differentiation observed during spermiogenesis in two starfishes shows that the central components of the mature acrosome are produced by Golgi activity. In the early spermatid, small Golgi‐derived vesicles enter the hydrated acrosomal mass and appear to contribute their membrane constituents to the acrosomal‐membrane precursor elements. A single lamella of smooth endoplasmic reticulum and fine‐fibrillar material associated with it surround the membraneprecursor complex. In a drastic reorganization by which the spermatid acquires antero‐posterior symmetry, the acrosome becomes embedded in the anterior part of the nucleus directly beneath the plasma membrane. All the other organelles congregate in the posterior cytoplasm; a thin layer of cytoplasm persists around the sides of the nucleus. During late spermiogenesis two additional acrosomal components become increasingly conspicuous. One is the layer of fine‐fibrillar material associated with the smooth endoplasmic reticular vesicles surrounding the Golgi‐derived elements. This material is finally pushed towards the center of the sperm head by a late accretion of fibrous product which appears to be synthesized throughout spermiogenesis by the ribosomes, and accumulates around the anterior part of the acrosome as the cytoplasmic matrix diminishes.

With the light microscope and the techniques of cytochemistry, Moriber (16) found that the proacrosornal granule of Gerris is divided into PASpositive and -negative regions, and that in the bipartite acrosome that develops from it (2) the sheath is PAS-positive and the core negative.…”

Acrosome Formation in the House Cricket

A B S T R A C TAcrosome formation during spermatogenesis in the house cricket was studied with the electron microscope. In the early spermatid there is a single Golgi body, called the acroblast, which is cup-shaped, the walls being composed of a number of parallel membranes. A pro-acrosomal granule then appears within the acroblast. Next, the granule migrates to the nucleus, where it becomes attached. The acroblast then migrates away from the attached granule and is eventually sloughed off. In the first stage of acrosome differentiation the granule assumes the shape of a blunt cone and its base invaginates deeply so that it becomes hollowed. Within the space created by the invagination a new structure forms which, from the first, has the shape of a hollow cone. The two cones constitute the mature acrosome. Both have a biconvex cross-section.
