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 کاملCo-culture of embryonic chick heart cells and ciliary ganglia induces parasympathetic responsiveness in embryonic chick heart cells.
We have developed a system for the co-culture of embryonic chick heart cells obtained from embryos at 3.5 days in ovo with ciliary ganglia from chick embryos at 7 days in vivo. After 3 days of co-culture, removal of the ciliary ganglia resulted in complete degeneration of axons within 6-8 h, leaving the post-innervated heart cell culture devoid of neurons. Embryonic chick heart cells at 3.5 day...
متن کاملCharacterization of outward potassium current in embryonic chick heart cells.
AIM To characterize a voltage-dependent outward K+ current in cultured heart cells of 14-16-day-old embryos of yellow chick. METHODS The patchclamp technique in the whole-cell configuration was used. RESULTS The kinetics and the pharmacology of the outward K+ current in our cell mold were different from those described in white chick. Like the calcium-activated K+ current, blocker of calciu...
متن کاملTetrodotoxin Desensitization in Aggregates of Embryonic Chick Heart Cells
Spontaneous beating of heart-cell aggregates from 4-day chick embryos was initially blocked by 10(-5) g/ml tetrodotoxin (TTX). With continued exposure to the drug, the fraction of blocked aggregates decreased from about 80% at 15 min to about 25% at 2-3 h, at which time, beating aggregates had become desensitized to the toxin, showing no response to a fresh dose. Aggregates from 5-day hearts we...
متن کاملDevelopmental changes in calcium currents of rabbit ventricular cells.
We investigated the postnatal development of L-type Ca2+ current (ICa) in enzymatically isolated adult (AD) and newborn (NB) (1-3-day-old) rabbit ventricular cells using the whole-cell, patch-clamp method. ICa was recorded with Cs(+)-rich pipettes and a Na(+)- and K(+)-free bath solution at 36 degrees C to eliminate other currents. ICa density (obtained by normalizing ICa to the cell capacitanc...
