In total, three different tissues from the rough-legged buzzard were obtained by culture and successfully cryopreserved and
then recovered. During the subculture process, biological characteristics including as cell morphology, growth curve, cell adhesion
rate, and karyotype were analyzed and compared, and overall all three kinds of tissue cells exhibited fibroblast-like growth.
Oviduct-derived cells had the strongest adherent ability, followed by lung-derived cells and trachea-derived cells. The doubling times
of lung-derived cells, trachea-derived cells, and oviduct-derived cells were 29.91±0.39 h, 33.18±0.21 h, and 30.67±0.28 h,
respectively, with population doubling times 3.54±0.01, 4.52±0.02, and 4.38±0.03, respectively. Likewise, we noted the chromosome
number of the rough-legged buzzard was 68, within the typical type of ZW. These results may potentially provide material and a basis for further research in the field, with the successful preservation of genetic information of rough-legged buzzard.
