Experimental antioxidant capacities (i.e., TEAC values) of various stabilized whole-cell progenitor tenocyte samples (i.e., containing 7.5 × 10⁶ cell equivalents/vial) or lyophilizate placebo samples containing two types of vial atmospheres (i.e., partial vacuum or atmospheric pressure air), respectively ¹. Values are presented as means assorted to the corresponding standard deviations. kGy, kiloGray; TEAC, Trolox equivalent antioxidant capacity.

		Non-Irradiated Samples	γ-Irradiated Samples (31 kGy)
Partial Vacuum Atmosphere	Placebo Samples	2.51 ± 2.77	58.18 ± 1.33
	Whole-Cell Samples	68.31 ± 3.90	91.68 ± 17.05
Air-Containing Atmosphere	Placebo Samples	1.23 ± 0.38	59.31 ± 3.13
	Whole-Cell Samples	74.81 ± 4.18	112.73 ± 7.02

¹ The composition of the atmosphere inside the sealed vial matched that of the freeze-dryer main chamber at the time of automatic vial stoppering.
