Values within the same embryo number group (including the overall of 5 embryo number groups) labeled with different capital letters differ at p<0.05, labeled with the same capital letter are not different from each other (p>0.05), and with no label are not different from each other (p>0.05). Values within the same donor cell type group (including the overall of 3 donor cell type groups) labeled with different small letters differ at p<0.05, labeled with the same small letter are not different from each other (p>0.05), and with no label are not different from each other (p>0.05).
