Identification of the rate of chimerism of different tissues with microsatellite markers in chicken chimeras.
The goal of our study was to evaluate whether private alleles can be defined in microsatellite markers for the breeds under investigation; to evaluate if these private alleles distinguish chicken chimera when using different tissues; to trace them back to the donor: Green-Legged Partridgelike and recipient: White Leghorn chicken breeds, and further on, to estimate the level of chimerism in each tissue. Private and common alleles were defined for donor and recipient chicken breeds in 3 loci. The rate of chimerism was defined based on private alleles present in liver, heart, breast muscle, femoral muscle and gonads. The highest rate of chimerism was observed in liver. A lower rate of chimersim was observed in gonads, and femoral muscle, and finally the lowest rate of chimerism was observed in breast muscle and heart.
