| Abstract |
Erectile dysfunction (ED) continues to be a significant problem for men following radical prostatectomy. We hypothesize that intracavernous injection of BDNF-hypersecreting human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) can ameliorate ED in a rat model of cavernous nerve electrocautery injury (CNEI). Forty-two male Sprague-Dawley rats were randomly divided into four groups: sham + PBS (n = 6), CNEI + PBS (n = 12), CNEI + hUCB-MSCs (n = 12) and CNEI + BDNF-hUCB-MSCs (n = 12). At day 28 post-surgery, erectile function was examined and specimens were harvested for histology. Immunofluorescence staining, Masson's trichrome staining and transmission electron microscopy were performed to determine the structural changes in corpus cavernosum. Cells that are injected into penis were labeled by BrdU and tracked by immunofluorescence staining. Three days post-surgery, the concentration of BDNF protein in penile tissues was measured by Western blotting. Rats intracavernosally injected with BDNF-hUCB-MSCs showed the most significant improvement in the ratio of maximal ICP to MAP (ICP/MAP). Histological examinations showed moderate recovery of nNOS-positive nerve fibers, ratio of smooth muscle to collagen and smooth muscle content in the CNEI + hUCB-MSCs group and remarkable recovery in the CNEI + BDNF-hUCB-MSCs group compared to the CNEI + PBS group. By TEM examination, atrophy of myelinated and non-myelinated nerve fibers was noted in CNEI + PBS group and significant recovery was observed in two treated groups. There were more BrdU-positive cells in the BDNF-hUCB-MSCs group than in the hUCB-MSCs group both in the penis and in the MPG. Three days post-surgery, the concentration of BDNF protein in penile tissues in BDNF-hUCB-MSCs group was much higher than in other groups. Intracavernous injection of BDNF-hypersecreting hUCB-MSCs can enhance the recovery of erectile function, promote the CNs regeneration and inhibit corpus cavernosum fibrosis after CNEI in a rat model. |

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 07 December 2015.
All research outputs
#20,657,128
of 25,374,917 outputs
Outputs from Geriatric Nephrology and Urology
#1,057
of 1,493 outputs
Outputs of similar age
#288,940
of 392,665 outputs
Outputs of similar age from Geriatric Nephrology and Urology
#11
of 19 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,493 research outputs from this source. They receive a mean Attention Score of 4.8. This one is in the 17th percentile – i.e., 17% 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 392,665 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 19 others from the same source and published within six weeks on either side of this one. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
