background: single domain antibodies from camel heavy chain antibodies (vhh or nanobody), are advantages due to higher solubility, stability, high homology with human antibody, lower immunogenicity and low molecular weight. these criteria make them candidates for production of engineered antibody fragments particularly in transgenic animals. objective: to study the development of transgenic chi...
Chick embryos are a great historical research model in basic and applied sciences. Along with other animal models, avian and specifically chicken embryo has been attended, as well. Avian fertilized eggs as a natural bioreactor are an efficient tool for producing recombinant proteins and vaccines manufacturing. Due to the limitations of birds' eggs for viral replication, avian stem cells culture...

To study expression and function of the vimentin gene, transgenic mice were generated by microinjecting the entire chicken gene plus 2.4 kilobases of 5' and 2.6 kilobases of 3' flanking sequences. All the transgenic mice obtained had incorporated multiple copies of the gene. RNA analyses demonstrated that the chicken vimentin gene was efficiently expressed in an appropriate tissue-specific patt...
Chicken egg lysozyme (cLY) is an enzyme with 129 amino acid (AA) residue enzyme. This enzyme is present not only in chicken egg white but also in mucosal secretions such as saliva and tears. The antibacterial properties of egg white can be attributed to the presence of lysozyme, which is used as an anti-cancer drug and for the treatment of human immunodeficiency virus (HIV) infection. In this s...
Transgenic chickens expressing human sequence antibodies would be a powerful tool to access human targets and epitopes that have been intractable in mammalian hosts because of tolerance to conserved proteins. To foster the development of the chicken platform, it is beneficial to validate transgene constructs using a rapid, cell culture-based method prior to generating fully transgenic birds. We...
The tissue-specific expression of the chicken liver cell adhesion molecule (L-CAM) was studied by generating transgenic mice. The rat insulin II promoter was fused to a chicken L-CAM cDNA or to chicken genomic L-CAM sequences. Mice carrying the cDNA showed no expression of L-CAM. Mice carrying L-CAM genomic sequences showed expression in the .8 cells of the pancreas, suggesting that sequences i...
We have previously shown that lentiviral vectors can be used to generate transgenic chickens efficiently and that expression of introduced transgenes is not silenced on transmission through the germline. Transgene expression can be targeted in the predicted tissue-restricted manner, for example: muscle-specific expression is restricted to skeletal muscle using the rat myosin light chain 3 gene ...
