- 1Lab model shows how embryo and uterus talk at implantation●A three-dimensional human co-culture system reveals reciprocal embryo–endometrial adaptation at implantation onset
Researchers have developed a three-dimensional human co-culture system that captures the earliest stage of implantation, revealing that the embryo and the endometrium actively adapt to each other rather than one simply responding to the other. The work, published in Nature, offers a new tool for studying human early pregnancy outside the body and could inform fertility research and treatment.
