| Abstract |
Currently, azoospermia is one of the most common diseases of male infertility. Stem cell research is the new hope for novel therapy with a higher degree of safety and lower cost. This study aimed to investigate the effect of umbilical cord blood-derived stem cells (" and mesenchymal "UCB-MSCs") and mono-cell layer implanted into the induced azoospermic mice testis. Stem cells were isolated from umbilical cord blood and CD34+ve cells were separated from negative one by Mini MACs column. At 5th week after single injection of busulfan, stained mesenchymal (CD34-ve), hematopoietic stem cells (CD34+ve) and their conjugate (mono-cell layer) were injected locally into testis. At the end of the study, MSCs group showed that mRNA levels of genes related to meiosis (Vasa, SCP3, and PgK2) were increased with significant decrease of FSH and LH levels, compared to control group. Histologically, most of the tubules restored normal architecture. In contrast, HSCs and mono-cell layer groups showed statically insignificant change of FSH, LH, and gene expression, compared to control group. Histologically, distorted seminiferous tubules, with reduction in sperm content, and interstitial mononuclear cellular infiltration were seen. There was significant increase in the optical density of PCNA immune reaction in MSCs group than azoospermia, HSCs, and mono-cell layer, while there was non-significant difference between MSCs and control group. The present study suggested that injection of MSCs into chemotherapeutic-induced azoospermia in mice improved testicular failure; histologically and functionally, by restoration of spermatogenic gene expression while HSC and mono-cell layer showed no effect on spermatogenesis added to that mono-cell layer may induce testicular tissue damage. |

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 08 February 2017.
All research outputs
#18,525,776
of 22,947,506 outputs
Outputs from Molecular and Cellular Biochemistry
#1,570
of 2,313 outputs
Outputs of similar age
#309,738
of 419,091 outputs
Outputs of similar age from Molecular and Cellular Biochemistry
#16
of 28 outputs
Altmetric has tracked 22,947,506 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,313 research outputs from this source. They receive a mean Attention Score of 3.9. This one is in the 21st percentile – i.e., 21% 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 419,091 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 28 others from the same source and published within six weeks on either side of this one. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
