| Abstract |
This study was performed to determine the effects of human placenta mesenchymal stem cell (hPMSC) transplantation on granulosa cell apoptosis and anti-Müllerian hormone (AMH) and follicle-stimulating hormone receptor (FSHR) expression in autoimmune drug-induced premature ovarian failure (POF) mice. The aim of this research is to investigate the mechanisms of hPMSCs on ovarian reserve capacity. The POF mice model was established by injection of zona pellucida 3 peptide (pZP3). hPMSC transplantation was conducted by intravenous injection into mice following pZP3 treatment. The follicle number was examined by histopathology. The serum levels of FSH, LH, E2, AMH and anti-zona pellucida antibody (AzpAb) were measured by enzyme-linked immunosorbent assay. AMH and FSHR expression in the ovary was analyzed by immunohistochemistry and western blot analysis. Granulosa cell apoptosis of the ovaries was examined by In Situ Cell Death Detection Kit. Granulosa cells were isolated and treated with SiAmh interference and hPMSC supernatant to observe the effects of AMH expression on granulosa cell apoptosis in vitro. The results showed that hPMSC transplantation can significantly recover the estrus cycle in the POF group. Morphological staining showed that the basal follicles and sinus follicles after hPMSC transplantation were higher in POF mice than in those without treatment, and the follicle number was significantly decreased with atresia. The serum levels of FSH, LH and AzpAb in the hPMSC transplantation group were reduced considerably, but the E2 and AMH levels were significantly increased. After hPMSC transplantation, the AMH and FSHR expression in ovarian tissue was significantly higher than in the POF group as determined by immunochemistry and western blot analysis. The FSHR expression was shown in granulosa cells only, and FSHR expression increases with AMH expressed in the ovary; granulosa cell apoptosis was decreased following hPMSC transplantation. The same results were observed from the in-vitro study. hPMSC transplantation can significantly improve the serum levels of high gonadotropin and low estrogen of POF mice, promote follicular development, inhibit excessive follicular atresia and granulosa cell apoptosis, and improve the ovarian reserve capacity. The mechanism may be achieved by increasing the expression of AMH and FSHR in ovaries. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 February 2018.
All research outputs
#20,462,806
of 23,020,670 outputs
Outputs from Stem Cell Research & Therapy
#2,060
of 2,429 outputs
Outputs of similar age
#377,700
of 440,210 outputs
Outputs of similar age from Stem Cell Research & Therapy
#51
of 58 outputs
Altmetric has tracked 23,020,670 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,429 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 440,210 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 58 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
