The Effect of chick Embryonic Somites on Neural Rosette Formation in Mouse Embryonic Stem Cells
purpose: The aim of the present study is to understand if EBs can generate neural rosette upon co-culture with chick embryo somites. Materials and Methods: The mouse ES cells, line Royan Bl, were cultured in hanging drops to induce embryoid bodies (EBs) formation. Somites were isolated from the chick embryos and then embedded in alginate solution. Finally, alginate beads containing somites were...
متن کاملPrimitive Erythropoiesis in Early Chick Embryogenesis
The primitive line of embryonic chick blood cells develop as a relatively homogeneous cohort of cells. Using an analysis based on the continuous uptake of thymidine-(3)H, we have established the generation time, G1, S, and G2 for progressively more mature generations of these immature erythroblasts. The data indicate that after the initiation of hemoglobin synthesis, the average cell will yield...
متن کاملThe embryonic origins of erythropoiesis in mammals.
Erythroid (red blood) cells are the first cell type to be specified in the postimplantation mammalian embryo and serve highly specialized, essential functions throughout gestation and postnatal life. The existence of 2 developmentally and morphologically distinct erythroid lineages, primitive (embryonic) and definitive (adult), was described for the mammalian embryo more than a century ago. Cel...
متن کاملEffects of histones on morphogenesis and differentiation in chick embryos.
The transcription of DNA is known to be inhibited in vitro by the presence of histones. This has been shown to be true for isolated nuclei, isolated chromatin, or for DNA alone (Bonner & Huang, 1962; Bonner, Huang & Gilden, 1963; Allfrey & Mirsky, 1963; Allfrey, Faulkner & Mirsky, 1964; Sonnenberg & Zubay, 1965). The masking of genomic sites in adult differentiated tissues seems the most probab...
متن کاملEvaluation of effect of chick embryonic notochord on neural induction of mouse embryonic stem cells
Introduction: The aim of this study was evaluate the ability of notochord to induce neural induction and/or differentiation of mouse embryonic stem cell to neuron and motor neuron, respectively. Methods: In order to produce embryoid bodies, ES cells line Royan B1 were grown in suspension in the absence of LIF for 4 days. EBs were divided into 4 groups. EBs in group 1 & 2 were further cultur...
