Stability values of housekeeping gene expression in lungs at different developmental stages for each sex.

aM stability values are calculated by geNorm. Gene stability increases while M value decreases.bStability values are calculated by NormFinder, Gene stability increases while stability value decreases.cStandard deviation (SD) is calculated by BestKeeper. Gene stability increases while SD value decreases.dAll studied developmental stages.Stability values of housekeeping gene expression in lungs at different developmental stages for each sex.

a. aM稳定性值通过geNorm算法计算得出。基因稳定性随M值降低而升高。
b. 稳定性值通过NormFinder算法计算得出。基因稳定性随该稳定性数值降低而升高。
c. 标准差（Standard Deviation，SD）通过BestKeeper算法计算得出。基因稳定性随SD值降低而升高。
d. 本研究涵盖所有受试发育阶段。不同性别个体肺组织中管家基因（housekeeping gene）在各发育阶段的表达稳定性值。
