Fig. 3From: RETRACTED ARTICLE: Effects of hPMSCs on granulosa cell apoptosis and AMH expression and their role in the restoration of ovary function in premature ovarian failure miceEffects of hPMSC transplantation on estrous cycles for pZP3-induced POF mice. Normal estrous cycles: a proestrus, b estrus, c metestrus, d diestrus. e Four patterns of estrous cycles were graded with the severity of abnormality (I–IV) as follows: I, normal; II, regular cycles with a shortened estrus; III, irregular cycles with a prolonged diestrus and normal or prolonged estrus; IV, no cyclicity. y axis represents the cycle day in proestrus or estrus (p-e) and metestrus or diestrus (m-d). Each circle (○) represents one mouse. Illustration is only represented by a mouse and the main purpose is to show the change of estrus cycle. f Total numbers of mice from each group categorized into the various estrous patterns (I–IV). **P < 0.01 indicates the statistically significant difference of the estrous cycle in mice with and without hPMSC transplantation.
