Modeling Human Organ Development and Diseases With Fetal Tissue–Derived Organoids

Abstract

Recent advances in human organoid technology have greatly facilitated the study of organ development and pathology. In most cases, these organoids are derived from either pluripotent stem cells or adult stem cells for the modeling of developmental events and tissue homeostasis. However, due to the lack of human fetal tissue references and research model, it is still challenging to capture early developmental changes and underlying mechanisms in human embryonic development. The establishment of fetal tissue–derived organoids in rigorous time points is necessary. Here we provide an overview of the strategies and applications of fetal tissue–derived organoids, mainly focusing on fetal organ development research, developmental defect disease modeling, and organ–organ interaction study. Discussion of the importance of fetal tissue research also highlights the prospects and challenges in this field.
