Research Overview

Spatial transcriptomics-based analyses of skeletal muscle development and pathologies

Recent technological advances in in situ imaging of RNAs have allowed us to examine gene expression patterns within individual cells and define cell identity in terms of cell type and state in intact tissues. I am investigating the development and homeostasis of the skeletal muscle through in situ sequencing, which is a spatial transcriptomic method invented by the group of Dr. Mats Nilsson. The skeletal muscle is composed of giant multi-nucleated myofibers surrounded by muscle stem cells (MSCs), which sustain the muscle tissue throughout our lives. I am interested in how myofibers and various cells generate the optimal microenvironment to maintain the regenerative potentials of MSCs and how MSCs are impaired during aging or degenerative diseases. I am also interested in where and how transcripts are localized and translated in lower motor neurons as well as myofibers since neuronal innervation of the muscle is vital for the homeostasis of the tissue. Although humans and rodents presumably share the mechanisms that regulate these processes, human-specific features are also expected considering the characteristic gene regulatory machineries, such as alternative splicing, in human cells. Therefore, I generate artificial tissues from human induced pluripotent stem cells and use them for my analyses. Through these studies, I aim to deepen our understanding of human skeletal muscle physiology and pathologies.
