Dear Editor,Embryonic stem cells(ESCs)and trophoblast stem cells(TSCs)are derived from blastocysts(Lu et al.,2001).Blastocyst-like structures(blastoids)are self-assembled structures formed by a combination of ESCs and TSCs(Rivron et al.,2018).To increase the success rate of blastoid formation and its similarity with the features of blastocysts,some reports showed that blastoid could also be derived from a combination of three cell lines,ESCs,TSCs,and extraembryonic endoderm cells(XENs),or novel type of stem cells(Sozen et al.,2018;Weatherbee et al.,2023:Wu et al.,2023;Zhang et al.,2023;Zhang et al.,2019).

作者： jia-Yi Huang Shu-Lan Zuo Qi Zhang Hong-Yang Dai Lei Yang Jing-Hua liu Cheng-bao jiang Key Laboratory of Aerospace Materials and Performance(Ministry of Education) School of Materials Science and EngineeringBeihang UniversityBeijing 100191China

Permanent magnets that can maintain a constant magnetic flux over a wide temperature range are highly desirable in certain applications such as precision instruments.2:17-type SmCo permanent magnets are promising for such instruments owing to their excellent high-temperature magnetic properties that can be further manipulated byadding heavy rare earth elements (HREs).
