Leukemia inhibitory factor increases the proliferation of human endometrial stromal cells and expression of genes related to pluripotency
Background: Concerning the low population of human endometrial mesenchymal
cells within the tissue and their potential application in the clinic and tissue
engineering, some researches have been focused on their in vitro expansion.
Objective: The aim of this study was to evaluate the effect of leukemia inhibitory
factor (LIF) as a proliferative factor on the expansion and proliferation of human
endometrial stromal cells.
Materials and Methods: In this experimental study, the isolated and cultured
human endometrial stromal cells from women at ovulatory phase aged 20-35 years,
after fourth passage were divided into control and LIF-treated groups. In the
experimental group, the endometrial cells were treated by 10 ng/ml LIF in culture
media and the cultured cells without adding LIF considered as control group. Both
groups were evaluated and compared for proliferation rate using MTT assay, for
CD90 marker by flow cytometric analysis and for the expression of Oct4, Nanog,
PCNA and LIFr genes using real-time RT-PCR.
Results: The proliferation rate of control and LIF-treated groups were 1.17±0.17
and 1.61±0.06 respectively and there was a significant increase in endometrial
stromal cell proliferation following in vitro treatment by LIF compared to control
group (p=0.049). The rate of CD90 positive cells was significantly increased in LIFtreated
group (98.96±0.37%) compared to control group (94.26±0.08%) (p=0.0498).
Also, the expression ratio of all studied genes was significantly increased in the LIFtreated
group compared to control group (p=0.0479).
Conclusion: The present study showed that LIF has a great impact on proliferation,
survival, and maintenance of pluripotency of human endometrial stromal cells and it
could be applicable in cell therapies
Investigating the Epidemiological Prevalence of Diabetes in Afghanistan from 2015 to 2019
Introduction: Diabetes is one of the most common metabolic disorders and is one of the top 10 leading causes of death in adults. Therefore, this study was conducted to investigate the epidemiological prevalence of diabetes in Afghanistan between 2015 and 2019. Methods: This descriptive cross-sectional study was performed using the information of diabetics registered in the system related to the Ministry of Health of Afghanistan from 2015 to 2019. Eventually, people's information, including age, gender, and place of residence, was entered into STATA software version 12 and analyzed using descriptive statistics tests. Results: The study, which was performed on 49,332 people with diabetes in 34 provinces and 8 regions of Afghanistan, found that most of the female studied were 55.2% (27,231) female and had the highest and lowest prevalence in the region. The order is related to South East and South. The average prevalence of diabetes per 10,000 people is about 62.13. Conclusions: The prevalence of diabetes in Afghanistan over a five-year period in men and women is on the rise, requiring more attention from relevant authorities to improve public health and prevent, control and treat chronic diseases such as diabetes
