科研新突破！这项技术有望探明胚胎移植失败原因

记者从中国科学院动物研究所获悉，该所于乐谦、王红梅研究员联合国内外科研团队，成功研发出基于微流控芯片的3D胚胎植入模型（3D子宫模拟芯片），首次在实验室完整复刻人类胚胎着床过程。相关成果12月23日在国际学术期刊《细胞》发表。

研究表明，中国接受辅助生殖技术治疗的患者中，约有10%的个体在经历3次或更多次胚胎移植后仍无法实现临床妊娠，从而陷入反复种植失败的困境，这是目前辅助生殖领域面临的重大挑战。而该技术的开发，则更加明确反复种植失败发生的核心病因、筛选个性化有效药物、简化检测流程。

科研团队发现：反复种植失败患者的子宫内膜细胞存在显著异常——凋亡细胞增多、增殖能力下降、DNA损伤累积，就像“孕育种子的土壤”变得贫瘠，即便移植优质胚胎也难以着床。

这项研究中，患者只需提供少量子宫内膜样本，就能通过模型明确自身是否存在子宫内膜功能异常，告别“病因不明”的困扰。

此外，科研团队借助3D人工子宫与人工胚胎技术，实现了对着床全过程的动态再现与系统解析。3D子宫模拟芯片还搭建了高效药物筛选平台。

总体来看，这项研究实现了基础研究与临床应用的衔接，为科研人员解析胚胎着床机制提供了标准化“体外实验室”，为早期发育异常、妊娠并发症等疾病研究提供了支撑。

Argentina selects Kansas City as World Cup base camp

Argentina will base in Kansas City for the 2026 FIFA World Cup as U.S. cities prepare for an influx of international teams and fans.

NEWYou can now listen to Fox News articles!

Kansas City, Kan. – With the 2026 FIFA World Cup just three months away, cities across the United States are racing to finalize training facilities that national teams will call home during the global tournament.

Among them is Kansas City, which will serve as the base camp for defending champion Argentina national football team, a major win for the region as it prepares to welcome both players and tens of thousands of international fans.

Base camps are critical to World Cup operations. They serve as home headquarters where teams live, train and recover while traveling between match sites throughout the competition.

"From private practice fields to player recovery rooms, these facilities are designed to support some of the biggest names in soccer," said Alan Dietrich, who has worked closely with organizers.

Local leaders have spent more than a year pitching their cities to international teams, hoping to showcase not just athletic facilities but the broader community.

"We started actually over a year ago with countries beginning to visit," Dietrich said.

Tourism officials say the opportunity extends far beyond the sport itself. Hosting a base camp allows cities to introduce themselves to global audiences and build long-term international relationships.

"We knew that the World Cup was going to be kind of our first chance and probably our biggest chance to be engaging these international markets," said Devin Aaron with Visit KC.

Early expectations had Argentina basing in Miami, but Kansas City ultimately stood out during the selection process.

"When Argentina visited, they really loved it here," Dietrich said. "They loved our facilities, they loved our people."

The team will train at Sporting Kansas City’s Compass Minerals National Performance Center, a state-of-the-art facility in Kansas City, Kansas that will serve as Argentina’s training home base during the tournament.

The complex features multiple professional grade fields and elite level training amenities designed for international competition.

Inside, players will have access to private dining areas, meeting rooms and dedicated recovery spaces designed to help them rest between matches.

"If they’ve traveled a lot and they’re tired, they can come in here, turn the lights out and get a nice nap," Dietrich added.

Up to 100,000 Argentine fans are expected to travel to Kansas City during the tournament, a preview of the global crowds set to flood World Cup host cities across the U.S.

Across the U.S., cities selected as host sites and base camps are preparing for similar surges, as teams finalize training locations and fans follow their national squads.
