Erratum to: Study of the reparative effects of menstrual-derived stem cells on premature ovarian failure in mice

Erratum

The original article [1] contains errors in Figs. 3i, j and 5e whereby the first column of each sub-panel is incorrectly labelled as having used GFP-staining; instead, the images were generated using TUNEL assays.

MenSC transplantation improves ovarian function after chemotherapy-induced injury. a Schematic of the experimental procedure used to explore the reparative effects of MenSCs in POF mice. b Changes in body weight between three groups (data expressed as mean ± SEM, *P < 0.05). c Changes in ovary weight across the three groups after 7 and 21 days (data expressed as mean ± SEM, *P < 0.05). d Macroscopic ovarian ovarian sizes in the three groups after 21 days. e Representative images showing H & E-stained ovary tissue sections in each group after 7 and 21 days. Scale bars = 100 μm. f Changes in follicle numbers in the three groups at 7 days (a) and 21 days (b) after MenSC transplantation (data expressed as mean ± SEM, *P < 0.05). g Serum E2 levels measured in each of the three groups. h Serum FSH levels measured in each of the three groups (data expressed as mean ± SEM, *P < 0.05). i Representative photograph showing TUNEL staining in ovary tissue sections after 7 days in each of the three groups. j Photograph showing TUNEL staining in ovary tissue sections after 21 days in each of the three groups. TUNEL-positive cells labelled green, and nuclei labelled blue (DAPI). Scale bars = 200 μm. k Quantitative analysis showing the percentage of TUNEL-positive cells in each group at 7 and 21 days after treatment (data expressed as mean ± SEM, *P < 0.05). CDDP cisplatin, DAPI 4′,6-diamidino-2-phenylindole, E2 oestradiol, FSH follicle-stimulating hormone, H&E haematoxylin and eosin, MenSC menstrual-derived stem cell, PBS phosphate-buffered saline, POF premature ovarian failure, TUNEL terminal deoxynucleotidyl transferase mediated dUTP nick end labelling

CM obtained from MenSCs improve ovarian function following chemotherapy-induced injury. a Schematic of the experimental procedure used to explore the reparative effects of CM in POF mice. b Serum E2 levels were measured in each of the three groups after 7 days. c Serum FSH levels were measured in each of the three groups after 7 days (data expressed as mean ± SEM, *P < 0.05). d Representative photomicrograph showing the results of H&E staining in each group at 7 days after injury. Scale bars = 100 μm. e Apoptosis evaluated using TUNEL staining in each group. Scale bars = 200 μm. CM conditioned media, CDDP cisplatin, DAPI 4′,6-diamidino-2-phenylindole, E2 oestradiol, FSH follicle-stimulating hormone, H&E haematoxylin and eosin, POF premature ovarian failure, TUNEL terminal deoxynucleotidyl transferase mediated dUTP nick end labelling
