    Lethal short rib syndrome of the Beemer type without polydactyly (1993)
    Springer
    Pediatric radiology 23 (1993), S. 325-326 
    Details
    ISSN: 1432-1998
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract A new case of Beemer shortrib dwarfism is reported and the clinical and radiological differences between this and Majewski type are discussed. The clinical variability related to the lack or presence of polydactyly is underlined, together with the importance of prenatal diagnosis.

    Chick hepatic lectins: An electron microscopic study on isolated hepatocytes during development (1991)

    Notes: Abstract We studied the carbohydrate recognition systems of hepatocytes isolated from 16-day-old embryos, 19-day-old embryos and chicks within 24 h of hatching. We localized and quantified at the ultrastructural level the binding sites for glycoproteins exposing terminal N-acetylglucosamine (GlcNAc), mannose and N-acetylgalactosamine (GalNAc) residues by means of protein-gold complexes. Binding sites specific for GlcNAc and mannose residues are present on hepatocytes from embryos and chicks. On the contrary GalNAc specific binding sites are exclusively observed on cells from 16-day-old embryos. The number and distribution of gold particles on hepatocyte cell surfaces depend on the binding sites and the age considered. We describe a modulation in the number of GlcNAc, and mannose specific receptors present on the cell surface between the embryonal stage and neonatal life.

    Expression of the asialoglycoprotein receptor in cultured rat hepatocytes is modulated by cell density (1996)
    Springer
    Bioscience reports 16 (1996), S. 477-484 
    Details
    ISSN: 1573-4935
    Keywords: Cultured hepatocytes ; asialoglycoprotein receptor ; cell density dependence

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The influence of cell density on expression of the asialoglycoprotein receptor system in primary cultures of rat hepatocytes was evaluated by measuring the level of the receptor specific mRNA. When the hepatocytes are cultured at high cellular density and are not in a proliferative condition, the transcript molecules of the receptor appear increased about 50% with respect to the low plating density, indicating a modulation of asialoglycoprotein receptor expression at transcriptional level. Such control may be dependent on surface molecules involved in cell specific reassociation, since it is well known that cell contacts play a significant regulatory role in differentiated cells.

    The effect of retinoic acid on the re-establishment of differentiated hepatocyte phenotype in primary culture (1998)

    Notes: Abstract  The usefulness of cultured hepatocytes is limited by the gradual loss of their typical physiological functions that occurs in vitro, mainly due to the absence of microenviromental conditions found in vivo. In this study we describe the effect of retinoic acid on the re-establishment of morphological characteristics and on the reorganization of the cytoskeletal network in cultured rat hepatocytes. Results obtained demonstrate that retinoic acid can influence hepatocyte differentiation, as regards the recovery of cell polarity, polyhedric shape and reformation of bile canaliculi and junctional complexes. The main target of this action appears to be the cytoarchitecture of cytoskeletal components, particularly cytokeratin filaments, which regain the configuration present in intact liver. The reorganization of the intermediate filaments does not seem to be dependent on the induction of higher levels of cytokeratin proteins, but rather appears to be due to post-translational regulation. The effect of retinoic acid on the cytoskeletal organization could determine the stabilization of intercellular contacts by means of junctions, leading to the appearance of morpho-functional characteristics typical of well-differentiated hepatocytes.
