Here, we present a protocol to efficiently generate human trophoblastic cells from human pluripotent stem cells using bone morphogenic protein 4 and inhibitors of the Activin/Nodal pathways. This method is suitable for the efficient differentiation of human pluripotent stem cells and can generate large quantities of cells for genetic manipulation.

Traditional, two dimensional cell culture techniques often result in altered characteristics with respect to differentiation markers, cytokines and growth factors. Three-dimensional cell culture in the rotating cell culture system (RCCS) reestablishes expression of many of these factors as shown here with an extravillous trophoblast cell line.
FAQs
Changes in gene expression provide the regulatory foundation for trophoblast differentiation, directing early embryonic cells toward specialized placental identities. These expression programs coordinate several outcomes at once, including cell fusion, migration, structural specialization, and endocrine activity. Their combined effects allow developing trophoblast populations to perform distinct roles during implantation, nutrient exchange, and communication between the embryo and mother.
Cell fusion and migration help trophoblast cells establish the physical organization required for placental development. Fusion contributes to the formation of specialized cell populations, while migration supports interactions with the uterine environment during implantation. Because these behaviors occur alongside gene-expression changes, studying them together can reveal how trophoblast cells acquire structural functions and participate in maternal-fetal interactions.
Differentiation produces distinct trophoblast populations rather than a single uniform cell type. These populations vary in their structural and endocrine functions, giving the developing placenta specialized capabilities. Examining those differences helps researchers connect particular cellular characteristics with implantation, nutrient exchange, and communication with the mother, while also clarifying how placental organization supports embryonic development.
Interactions with the uterine environment form an important part of trophoblast differentiation. They help coordinate cellular behaviors with the conditions surrounding implantation and contribute to the development of specialized placental functions. Studying this relationship provides a biological framework for investigating how communication between embryonic cells and maternal tissues supports placental development and may be disrupted in implantation failure.
Stem cell and organoid models provide research systems for examining trophoblast differentiation and human placental function. They can be used to investigate how cells acquire specialized identities, organize placental activities, and communicate with their surroundings. These models extend study beyond observations of development and support focused investigation of processes relevant to implantation and maternal-fetal interactions.
Trophoblast differentiation is relevant to implantation failure, preeclampsia, and other pregnancy complications because placental development depends on coordinated cellular specialization and interaction with the uterine environment. Research in this area can connect altered trophoblast behavior with impaired placental functions. It also helps establish experimental models for studying how developmental disturbances affect communication between the embryo and mother.
