Approximately 2-3 g flying rib bone pieces in the entire cross section of bony rib were surgically removed from 3 anaesthetized [SBH-Ketamine (2.5 mg/kg live weight) combined with Xylazine (0.2 mg/kg live weight) i.m. injection] 6, 7 and 8 year old Cervus elaphus stags. (Cast antler pairs weighed 7-8 kg for each animal.) Removed rib pieces were extensively washed in PBS for eliminating blood and marrow contamination, than immediately frozen in liquid nitrogen. The time of tissue collections were (i) within the period of the active mineralization of antler, at the beginning of June when skeletal osteoporosis takes place, (ii) in the fitness improvement period with velvet shedding in late July, that is the 'regenerating time' and (iii) in the period of late autumn dwell at the end of November when in the skeleton the mineral mobilization and deposition are dynamically equilibrated (BMD is in steady state). Each comparison performed on Platforms GPL4052 and GPL5352.
