Dynamic expression of calretinin in embryonic and early fetal human cortex
Calretinin (CR) is one of the earliest neurochemical markers in human corticogenesis. In embryos from Carnegie stages (CS) 17 to 23, calbindin (CB) and CR stain opposite poles of the incipient cortex suggesting early regionalization: CB marks the neuroepithelium of the medial boundary of the cortex with the choroid plexus (cortical hem). By contrast, CR is confined to the subventricular zone (S...
متن کاملExpression of apoptosis in the developing human cephalic region during the embryonic and early fetal period.
The aim of our work was to study the expression of apoptosis in the cephalic region in human embryonic and fetal material. Twelve human embryos and fetuses were processed by routine histological technique and then studied using the Boehringer-Mannheim Company kit for TUNNEL technique. Rich appearance of apoptotic cells was typical for mesenchyme and for tissues of the mesenchymal origin. Disper...
متن کاملEmbryonic and early fetal development of the human neocortex.
Early corticogenesis was studied in human embryos and early fetuses from Carnegie stages 16 to 22 (5-8 gestational weeks) by using immunohistochemistry for Reelin (Reln), calretinin (CR), and glutamic acid decarboxylase (GAD). A first population of Reln-positive cells appears in the neocortical anlage at stage 16 and increases in number at stages 17-18. At stages 19-20, a monolayer of horizonta...
متن کاملMucin gene expression in human embryonic and fetal intestine.
BACKGROUND The intestinal epithelium is covered by a continuous layer of mucus which is secreted by well differentiated epithelial cells. Disregulation of the expression of mucins has been reported to have possible implications in the neoplastic process which affects intestinal mucosae. It is well known that preneoplastic and neoplastic tissues can express fetal phenotypic characteristics. AI...
متن کاملExpression of Endoderm and Hepatic Specific Genes after in vitro Differentiation of Human Embryonic Stem Cells
Background: Human embryonic stem cells (hESC), which are derived from the inner cell mass of the blastocysts, have been considered to be pluripotent cells. In this study we examine the differentiating potential of hESC into hepatocytes by characterization of the expression of endoderm and liver-specific genes. Methods: hESC were cultivated in suspension to form aggregates, the embryoid bodies. ...
