Research Overview

From making segments to reconstruct complete human and non-human primate body plan in a dish

During early vertebrate embryo development, transiently epithelialized blocks composed of mesodermal cells termed somites periodically appear with segmental patterns to architect the body plan of the entire conceptus. As disruption of sequential somite formation and segmentation will give rise to vertebral defects, understanding biological and molecular mechanisms underlying periodic development of somites can provide clues to reveal the pathology of congenital diseases. However, due to the lack of appropriate in vitro models, it has been so far very difficult to study human somitogenesis and subsequent developmental events. Recently, an in vitro 3D model (i.e., axioloid) succeeded to perfectly recapitulate human somite segmentation and proper rostrocaudal patterning (Yamanaka and Hamidi et al, Nature, 2022). Thus, axioloids will shed light on understanding human axial development and molecular pathologies underlying congenital diseases of the human spine. Moreover, further investigations using axioloids can potentially mimic additional embryonic structures such as neural tube and notochord and provide insights into the formation of sclerotome and myotome compartments in each segment. Here, I propose to systemically study and investigate (1) molecular pathologies of congenital diseases resulting from defective somitogenesis using axioloids, (2) key metabolic pathways regulating proper segmentation and somite differentiation and (3) establish more advanced synthetic embryo models of axial development in human and non-human primates. I will address and achieve the objectives of my planned research as a postdoctoral researcher at Alev group in ASHBi.


Keun-Tae obtained his Ph.D. in Stem cell biology at Sogang University, Republic of Korea in August, 2020. He continued his Postdoctoral training at College of Pharmacy, Seoul National University in Republic of Korea since 2020 to 2022. After his visiting periods at the Institute of Molecular Biotechnology of Austrian Academy of Sciences (IMBA) in Vienna during 2022, he joined the Alev group from January, 2023.
