光唇鱼(Acrossocheilus fasciatus)卵原干细胞提取、冻存及移植研究

open access: yesHaiyang yu huzhao
为更好地保护和开发光唇鱼(Acrossocheilus fasciatus)资源,进行了光唇鱼卵原干细胞提取、冻存和移植研究。结果显示,光唇鱼卵原干细胞呈椭圆形,长径和短径分别为(16.52±0.87) µm、(10.66±0.87) µm。低温冻存光唇鱼卵巢时以10%的DMSO作为保护剂效果最好,从冻存卵巢中提取卵原干细胞的效率可达新鲜卵巢的42.22%±1.02%。以孵化出膜3日龄斑马鱼仔鱼为受体,将提取的光唇鱼卵原干细胞用PKH26荧光染料标记后移植入受体鱼腹腔。荧光显微镜观察显示,移植后1~5 ...

Lipoxin A4 Regulates M2 Macrophage‐Derived Exosomal miR‐25‐5p to Protect Cell Pyroptosis in Bronchopulmonary Dysplasia

open access: yesThe FASEB Journal, Volume 39, Issue 22, 30 November 2025.
In premature infants with BPD treated with LXA4, circulating monocytes are reprogrammed and polarized into M2‐Mφs and then migrate into the lungs. The M2‐exo released by M2‐Mφs, which is rich in miR‐25‐5p, downregulates the PI3K/AKT signaling pathway by acting on the target gene NRBP2, thereby inhibiting the pyroptosis of AT2.
