“…Immunohistochemical studies with a smooth muscle actin antibody have been carried out to confirm the electron microscopical results. In agreement with the immunohistochemical studies of Miura et al (1996) in bovine foetuses myoepithelial cells are found surrounding acini and intercalated ducts. In their study myoepithelial cells are first detected in a 260 mm foetus, slightly earlier than in the present observations (330 mm CRL).…”

“…The morphology and ultrastructure of the parotid gland in adult bovine species has been studied by different authors [Shackleford and Wilborn, 1969; Thomé, 1989; Mansouri and Mehrabi, 2000 (buffalo)]. In contrast very little information restricted to light microscopical results (Asari et al, 1994; Miura et al, 1996) is available on the parotid gland ontogenesis of the big group of ruminants especially cattle. In other mammalian species the ontogenesis of the parotid gland has been extensively examined on the light and electron microscopical level including man (Hammar, 1901; Yaku, 1983; Donath et al, 1978; Lee et al, 1990; Guizetti and Radlanski, 1996), cat (Knospe and Böhme, 1995), rat (Redman and Sreebny, 1970a,b, 1971; Redman et al, 1980), mouse (Moral, 1919) and rabbit (Leeson and Forman, 1981).…”

The development of the parotid gland was examined in 36 bovine embryos and foetuses with a crown-rump-length (CRL) from 28 up to 1000 mm by light, transmission electron microscopical and actin-immunohistochemical methods. The anlage of the parotid gland in an embryo with 28 mm CRL can be found at the lateral angle of the primitive oral cavity as a local thickening of the epithelium. During the second month, the differentiation of primary ducts and endbuds starts and a lumen develops in the primary ducts. At the end of the second month a lumen appears in the terminal endbuds. In the immature endpiece cells first secretory granules can be seen from a CRL of 240 mm. In the third month differentiation between intra- and inter-lobular ducts is possible. Immature myoepithelial cells present as a basal layer of flattened cells between the epithelial cells and the basement membrane at the end of the second month. During further development they increase in number, become more flattened and form long cellular processes. At the end of the fourth month isolated actin filament bundles are formed, which were also detected by an antibody against smooth muscle actin. The actin filaments condense continuously until they fill the cell processes completely at the end of foetal development.

“…This may reflect changes in the biological functions of cells during pre-and postnatal development. Morphological changes and distribution of secretory acinar cells, duct segment and myoepithelial cells (MEC) of bovine developing parotid glands have been reported by Kasuga et al [1980] and Miura et al [1996]. According to the findings of the former study, immature acinar cells had not yet developed distinct secretory granules in the cytoplasm of a 26-cm CRL fetus, estimated to be 4-5 months of fetal age.…”

The distribution of bovine carbonic anhydrase isozyme VI (CA-VI), purified from bovine saliva, was studied immunohistochemically using antiserum against bovine CA-VI in bovine parotid glands during fetal and postnatal development. A weak expression of CA-VI in undifferentiated epithelial cells and ductal cells was observed in a 4- to 5-month-old fetus with a 26-cm crown-rump length. The reaction in both acinar and ductal cells subsequently persisted during late gestation and birth. Although anti-CA-VI reactivity was still seen in both regions immediately following birth, the reactivity had almost completely disappeared from most duct segments by 1 month following birth. Changes in the localization and time-dependent expression of the isozyme in parotid glands may reflect changes in the biological function of structurally closely related isozymes.
