Abstract
The spontaneous assembly of nanoscale building blocks into continuous semipermeable membranes is a key requirement for the structuration of synthetic protocells. Engineering the functionality and programmability of these building units provides a step toward more complex cell-like entities with adaptive membrane properties. Inspired by the central role of protein (lectin)-carbohydrate interactions in cellular recognition and adhesion, we fabricate semipermeable polysaccharide-polymer microcapsules (polysaccharidosomes) with intrinsic lectin-binding properties. We employ amphiphilic polysaccharide-polymer membrane building blocks endowed with intrinsic bio-orthogonal lectin-glycan recognition sites to facilitate the reversible noncovalent docking of functionalized polymer or zeolitic nanoparticles on the polysaccharidosomes. We show that the programmed attachment of enzyme-loaded nanoparticles gives rise to a membrane-gated spatially localized cascade reaction within the protocells due to the thermoresponsiveness of the polysaccharidosome membrane, and we demonstrate that extended closely packed networks are produced via reversible lectin-mediated adhesion between the protocells. Our results provide a step toward nanoscale engineering of bioinspired cell-like materials and could have longer-term applications in synthetic virology, protobiology, and microbiosensor and microbioreactor technologies.

Abstract
A selection of lectins was used to investigate developmentally regulated changes in the distribution of cell surface oligosaccharides during the gastrulation and neurulation stages of early chick embryo development. Lectins from three specificity classes were used: glucose/mannose specificity (concanavalin A [Con A], Lens culinaris agglutinin [LCA], Pisum sativum agglutinin [PSA]); N-acetylglucosamine specificity (Lycopersicon esculentum agglutinin [LEA], wheat germ agglutinin [WGA], succinylated WGA [sWGA]); N-acetylgalactosamine/galactose specificity (Dolichos biflorus agglutinin [DBA], soybean agglutinin [SBA], Sophora japonica agglutinin [SJA], Bandeiraea (Griffonia) simplicifolia lectin I [BSL I], peanut agglutinin [PNA], Artocarpus integrifolia lectin [Jacalin], Ricinus communis agglutinin-1 [RCA-1], Erythrina cristagalli lectin [ECL]). At gastrulation stages, patterns of lectin binding could be distinguished in the epiblast, mesoderm, and endoderm cell layers. The primitive streak failed to bind any of the lectins, but LEA and WGA bound to the epiblast in regions lateral to the streak, indicating the loss of some glucosamine residues medially in preparation for the ingression movements of gastrulation. Several lectins showed marked binding to the mesoderm cells after their passage through the primitive streak; these were LCA, PSA, WGA, sWGA, BSL, and most particularly PNA. Therefore, the epithelial-mesenchymal transformation from epiblast to mesoderm at the primitive streak is accompanied by cell surface oligosaccharide changes in the epiblast and mesoderm that involve all classes of lectins including the PNA-binding sequence Gal beta 1-3GalNAc. Ultrastructurally, PNA was shown to bind extracellularly to matrix fibrils. Jacalin, having the same sugar specificity as PNA, but binding to serine/threonine linked chains rather than asparagine linked chains showed no binding to the mesoderm.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In the present investigation we localized binding sites for the lectins WGA (wheat germ agglutinin), RCA I (Ricinus communis agglutinin), LFA (Limax flavus agglutinin) and SBA (soya bean agglutinin) in the 7-day-old mouse embryo at the ultrastructural level. Lectin binding sites were localized on formaldehyde fixed embryos, embedded in LR-Gold, using gold-labelled lectins. Binding sites for WGA and RCA I were observed at the surface of the embryonic ectoderm oriented towards the proamnion cavity and the outer surface of the extraembryonic and the embryonic endoderm. Staining for SBA and LFA binding sites was seen in the basement membrane of the ectoderm. Moreover, binding sites for LFA were observed in the nucleoli of cells of the ectodermal, the mesodermal and the endodermal layer and in free ribosomes located in the cytoplasm of these cells.

Abstract
Cell surface carbohydrates in the neurulating ectoderm of bantam chick embryos of stage 6-11 were examined using the fluorescein isothiocyanate-labeled and ferritin-labeled peanut lectin, Arachis hypogaea agglutinin (PNA), which is Gal beta 1----3GalNAc specific. Weak fluorescence showing PNA binding sites was seen on the apical surfaces of neural plate cells. On the surfaces of neural tube cells the fluorescence was more intense and appeared as a band. When using ferritin particles as a quantitative EM marker, only a few PNA binding sites covering the apical surfaces of the basal plate cells during the neural plate stage were seen (274.3 +/- 18.67 ferritin particles/micron 2). As neural tube formation advanced, the number of the ferritin labeled PNA binding sites increased as was to be expected from the fluorescent label experiment. At the neural ridge contact stage there were 2.5 times more binding sites than at the neural plate stage. After this period, the lectin binding sites showed no significant changes. These results were the inverse of those for RCAI or WGA lectins previously reported by us. These observations suggest that sugar residues or the sugar-chain skeletons on the neuroectoderm are altered during neurulation.

Abstract
The emphasis of this review is on the primitive streak of the chick embryo, collated with such information as is available on the mouse embryo. Little modern work has been published on any reptile primitive streak. The following topics are considered: evolutionary significance; formation of the primitive streak; ingression and de-epithelialisation; the basal lamina; migration from the primitive streak of the endoderm and mesoderm; the role of the extracellular matrix; changes in cell adhesiveness; regression of the primitive streak and its role in body patterning; the primitive streak and induction.

Abstract
Cell surface sugar residues in neurulating ectoderms of bantam chick embryos of stage 4-11 were examined using ferritin-labeled Ricinus communis (RCAI) and Wheat germ agglutinin (WGA). RCAI binding sites densely covered the apical surfaces of the basal plate cells during the neural plate stage (1,322.8 +/- 28.8 ferritin particles/micron 2). As neural tube formation advanced, the number of receptors decreased as a result of an increase in the extent of the sparsely covered regions. The decrease in receptors for WGA occurred in a similar manner but more rapidly. By the stage of development at which the opposite sides of the neural ridges meet at the dorsal midline, the receptors for WGA were reduced to about half. After this period, the two lectin receptors did not show significant changes. This result suggests that sugar residues or the sugar-chain skeleton on basal plate cells are altered during neurulation.

Abstract
Chick embryo mesoderm cells are various stages of differentiation were cultured in three-dimensional matrices of hydrated collagen. The tissues used were: stage 5 mesoderm from regions adjacent to the primitive streak; stage 12 mesoderm, comprising somitic, unsegmented (segmental plate) and lateral plate mesoderm; and stage 18 sclerotome. Explants were examined by phase contrast microscopy, including time-lapse, and scanning and transmission electron microscopy. The cells showed an increased ability to adhere to, and move in, the collagen gel with advancing stage. Of the stage 12 tissues, the unsegmented mesoderm was initially the slowest to grow out of the explant. Sclerotome cells showed by far the greatest ability to move within the gel. Where the collagen fibrils were randomly oriented, the cell morphology was polypodial and advancing lamellipodia showed clear undulations at their leading edges. A distinction was drawn between these undulations and the classical major ruffles which are seen in two-dimensional culture to uplift and pass back along the cell surface. The latter were not seen in the collagen matrix and were presumably suppressed by the three-dimensional culture configuration while the leading edge undulations were not. Ultrastructural examination showed that the cells possessed patches of amorphous material on their surface, which was sometimes interposed between the plasma membrane and collagen fibrils. Addition of hyaluronic acid (2 mg/ml) had an effect only the segmented mesoderm, where outgrowth was enhanced. Although the addition of plasma fibronectin (50 micrograms/ml) to the cultures did not affect any of the tissues, the removal of this substance, by antifibronectin antiserum or by the use of fibronectin depleted serum, inhibited outgrowth in most cases. The only tissue not reproducibly inhibited in this way was sclerotome. Alignment of the collagen fibres by the explants was observed, accompanied by an elongation of the outgrowing cells which, in bipolar form, preferentially moved up and down the aligned tracts. Scanning electron microscopy suggested that cell processes attached to, and presumably exerted tension on, bundles of fibrils thereby pulling them into line. Cell-to-cell contact was not accompanied by contact paralysis as judged by time-lapse micrography.

Abstract
The endocytosis of cationized ferritin and of a phosvitinferritin conjugate by cells of the chick embryo area pellucida has been examined. Cationized ferritin was bound mainly to the free surface of the epiblast but was absent from the region of the primitive streak. The binding was patchy and experiments suggest that the anionic sites which bind cationized ferritin are themselves naturally clustered. Uptake of cationized ferritin was exclusively by coated pits. The resulting coated vesicles delivered the cationized ferritin to membrane-bound sites of accumulation in the cytoplasm and to the close vicinity of Golgi bodies. The cationized ferritin was frequently found to share intracellular vacuoles with yolk granules. The uptake was not affected by the presence of microfilament or microtubule-inhibiting agents. Native ferritin, even at concentrations forty times that of cationized ferritin, was not bound or endocytosed. Coated pits in the epiblast were often associated with overlying extracellular yolk granules. This suggested that the yolk might be inducing the formation of the coated pits. The yolk protein phosvitin was coupled to ferritin and this conjugate was found to be endocytosed by coated pits. This uptake was inhibited in the presence of an excess of free phosvitin but not by albumin, indicating some selectivity for phosvitin over other proteins. The phosvitin conjugate was also found sharing intracellular vacuoles with yolk. We conclude that the cells of the area pellucida, and in particular those of the epiblast, have an active coated vesicle uptake system which may be able to selectively endocytose yolk or yolk protein.

Abstract
The distribution of alcian blue (AB) positivity, and its sensitivity to streptococcal and testicular hyaluronidase, were studied in primitive streak stage chick blastoderms. Accumulation of hyaluronate was observed in deep layer (DL) cells and on laterally migrating middle layer (ML) cells. During the formation of the middle layer, a first stage, namely de-epithelialization of the upper layer cells, is recognized and correlated with the absence of hyaluronate. A second stage, namely migration of the de-epithelialized upper layer cells laterally to the edge of the area pellucida, is correlated with the accumulation of AB-positivity. The AB-staining also demonstrated the accumulation of both sulphated and not-sulphated mucopolysaccharides, where a basal lamina is present.

Abstract
Primitive streak stage chick blastoderms were cultured for 30 min on a medium containing tritiated glucosamine. Light microscope autoradiography revealed extracellular labeling, and pretreatment of the sections with testicular hyaluronidase suggested the glycosaminoglycan nature of the labeled products. After incorporation of the tritiated precursor, some blastoderms were transferred to a chase medium, and cultured for 30, 90, 210 min. The changes is distribution of the labeled testicular hyaluronidase-sensitive macromolecules during the chase experiment illustrated the ingression of cells in the primitive streak stage chick blastoderm. Grain density differences, resulting from the various chase periods, suggested the renewal of the testicular hyaluronidase-sensitive fraction.
