干细胞诱导分化为毛囊及再生的研究进展

BACKGROUND:Stem cells have the potential to differentiate into various organs and tissues. In recent years, stem cells have been proved to differentiate into hair follicles under certain conditions. OBJECTIVE:To review the research progress and prospect of stem cells differentiating to hair follicles, thereby providing a reliable basis for clinical treatment of serious hair follicle injury. METHODS:A computer-based search of PubMed, EMBASE, WanFang, CNKI databases was performed for related articles published between 2013 and 2015, using the keywords of “cell hair, follicle stem, medicine regenerative, differentiation” in English and Chinese. A total of 207 articles were retrieved, and finally 34 articles were included in result analysis. RESULTS AND CONCLUSION:Stem cells from different sources all have the ability to differentiate into hair follicles under certain inductions. However, it is important to seek more scientific and rational methods for the differentiation of stem cells into hair follicles based on overcoming their own shortcomings. A great progress has been made in animal experiments and subclinical trials, and even a great breakthrough in some aspects. Further studies on combining the advantages and overcoming the shortcomings of various stem cells during differentiation are required for the clinical treatment of serious hair follicle injury.     

整合素连接激酶(ILK)通过调控自噬影响深度烧伤创面愈合北大核心CSCD

目的:探讨整合素连接激酶(ILK)在大鼠深度烧伤创面的表达变化及其对创面愈合的影响和机制。方法:10只Wistar大鼠随机分为正常组和实验组,每组5只,实验组大鼠建立背部皮肤深Ⅱ度烧伤模型,正常组大鼠不做任何处理,免疫组化染色和Western blot检测烧伤创面ILK表达;另取45只大鼠建立背部皮肤深Ⅱ度烧伤模型后随机分为对照组、阴性对照组和ILK组,每组15只,阴性对照组和ILK组大鼠创面分别注射pEGFP-C1慢病毒和pEGFP-C1-ILK慢病毒,对照组注射等量生理盐水;于1 d、7 d、10 d、14 d、21 d观察创面愈合情况,10 d时取创面组织,ELISA测定创面组织TNF-α、IL-1β、IL-6、IL-10表达;21 d时取创面组织,HE染色观察创面组织形态变化,免疫组化染色检测创面组织自噬标志蛋白轻链蛋白3(LC3)表达,Western blot检测自噬相关蛋白表达。结果:烧伤大鼠创面组织ILK表达较正常大鼠皮肤组织显著升高(P<0.05);ILK组大鼠创面愈合率在第7、14、21天时均显著高于对照组和阴性对照组(P<0.05);与对照组和阴性对照组比较,ILK组大鼠创面组织病变坏死程度明显降低,炎症细胞浸润减少,TNF-α、IL-1β及IL-6含量均显著降低(P<0.05),IL-10含量显著升高(P<0.05),LC3阳性表达平均光密度值显著降低(P<0.05),LC3-Ⅱ/Ⅰ显著降低(P<0.05),Beclin-1蛋白表达显著下调(P<0.05),p62蛋白表达显著上调(P<0.05)。结论:ILK在深度烧伤大鼠创面组织表达增加,过表达ILK可减轻创面炎症反应,抑制自噬,促进烧伤创面愈合。
