1Stem cell-based therapy for human diseases显示文摘Recent advancements in stem cell technology open a new door for patients suffering from diseases and disorders that have yet to be treated.Stem cell-based therapy,including human pluripotent stem cells(hPsCs)and multipotent mesenchymal stem cells(MSCs),has recently emerged as a key player in regenerative medicine.hPSCs are defined as self-renewable cell types conferring the ability to differentiate into various cellular phenotypes of the human body,including three germ layers.MsCs are multipotent progenitor cells possessing self-renewal ability(limited in vitro)and differentiation potential into mesenchymal lineages,according to the International Society for Cell and Gene Therapy(ISCT).This review provides an update on recent clinical applications using either hPSCs or MSCs derived from bone marrow(BM),adipose tissue(AT),or the umbilical cord(UC)for the treatment of human diseases,including neurological disorders,pulmonary dysfunctions,metabolic/endocrine-related diseases,reproductive disorders,skin burns,and cardiovascular conditions.Moreover,we discuss our own clinical trial experiences on targeted therapies using MsCs in a clinical setting,and we propose and discuss the MSC tissue origin concept and how MSC origin may contribute to the role of MSCs in downstream applications,with the ultimate objective of facilitating translational research in regenerative medicine into clinical applications.The mechanisms discussed here support the proposed hypothesis that BM-MSCs are potentially good candidates for brain and spinal cord injury treatment,AT-MSCs are potentially good candidates for reproductive disorder treatment and skin regeneration,and UC-MsCs are potentially good candidates for pulmonary disease and acute respiratory distress svndrometreatment.Duc M.Hoang Phuong T.Pham Trung Q.Bach Anh T.L.Ngo Quyen T.Nguyen Trang T.K.Phan Giang H.Nguyen Phuong T.T.Le Van T.Hoang Nicholas R.Forsyth Michael Heke Liem Thanh Nguyen 2022Signal Transduction and Targeted Therapy2022,7,9:7
2MicroRNA-22 inhibits proliferation and promotes differentiation of satellite cells in porcine skeletal muscle显示文摘Pig is an important economic animal in China. Improving meat quality and meat productivity is a long time issue in animal genetic breeding. Micro RNAs(mi RNAs) are short non-coding RNAs that participate in various biological processes, such as muscle development and embryogenesis. mi R-22 differentially expresses in embryonic and adult skeletal muscle. However, the underlying mechanism is unclear. In this study, we investigated mi R-22 function in proliferation and differentiation of porcine satellite cells(PSCs) in skeletal muscle. Our data show that mi R-22 expressed in both proliferation and differentiated PSCs and is significantly upregulated(P<0.05) during differentiation. After treated with the mi R-22 inhibitor, PSCs proliferation was significantly increased(P<0.05), as indicated by the up-regulation(P<0.01) of cyclin D1(CCND1), cyclin B1(CCNB1) and down-regulation(P<0.05) of P21. Conversely, over-expression of mi R-22 resulted in opposite results. Differentiation of PSCs was significantly suppressed(P<0.05), evidenced by two major myogenic markers: myogenin(Myo G) and myosin heavy chain(My HC), after transfecting the PSCs with mi R-22 inhibitor. Opposite results were demonstrated in the other way around by transfection with mi R-22 mimics. In conclusion, the data from this study indicated that mi R-22 inhibited the PSCs proliferation but promoted their differentiation.Hong Quyen Dang XU Gu-li HOU Lian-jie XU Jian HONG Guang-liang Chingyuan Hu WANG Chong 2020Journal of Integrative Agriculture2020,19,1:5
3Relationship between skin fold thickness and insulin resistance in the essential hypertensive patients in Vietnam显示文摘Previous studies reported a close relationship between obesity and insulin resistance in the essential hypertensive patients. Objective In this study, we examined the relationship between the skin fold thickness and insulin resistance then developed a formula to estimate the insulin resistance index according to the skin fold thickness in the essential hypertensive patients. Subjects and Methods Medical records of 80 patients (37 males, 43 females) were reviewed and the data were tabulated. Anthropometric indexes (including height, weight, waist circumference, hip circumference, and skins fold thickness at 5 fatty difference points on the Erdheim diagram), fasting plasma glucose and insulin concentration were recorded. The mean age was 57.0±9.2 years. The insulin resistance index was calculated following the Homeostasis Model Assessment (HOMA) formula. Results Compared with the group with BMI<23kg/m2, the group with BMI≥23 kg/m2 had higher fasting insulin concentration (8.85 ± 4.97 pmol/L vs 15.60 ± 8.70 pmol/L, P<0.001 ) and higher insulin resistance index in (2.15±1,24 vs 3.76±2.22, P<0.001). No significant difference in fasting plasma insulin concentration,insulin resistance index between male and female was observed (P>0.05). There was a positive correlation between skin fold thickness and the fasting insulin concentration and insulin resistance index. The skin fold thickness at point A8 had the best coefficient correlated with fasting plasma insulin(r=0.79, P<0.001) and insulin resistance index (r= 0.79, P < 0.001). A formula to estimate the insulin resistance index by skin fold thickness at point A8 as: Insulin resistance index = 0.12 × [skin fold thickness at A8 point (mm)] - 1.Conclusion: In the essential hypertensive patients, the formula to estimate insulin resistance index as 0.12 × [skin fold thickness at A8 point (mm)]-1 may predict accurately the level of insulin resistance.Toan C Nguyen Khoa TA Pham Quyen TL Do Cuong T Nguyen Diep D Nguyen Vinh G Le Cong D Nguyen 2005Journal of Geriatric Cardiology2005,2,4:4
