Yoon laboratory has a long-term research interest in understanding the molecular mechanisms by which tissue homeostasis and regeneration are regulated. We are currently studying two specific tissues, skeletal muscle and lung, by utilizing both in vitro cell culture and in vivo mouse models.
Skeletal Muscle
Skeletal muscle tissue primarily functions for body locomotion and energy metabolism and is a highly dynamic tissue that responds to various physiological changes such as physical damage, exercise, nutrition, aging, and disease conditions. During the regeneration process after muscle injury or exercise, muscle stem cells (also called satellite cells) residing within the skeletal muscle generate nascent myofibers for repairing the damaged muscle or building additional muscle mass. Independent from the stem cell activity, regulation of myofiber mass is another key cellular process for skeletal muscle homeostasis. A balance between catabolic and anabolic metabolism of cellular proteins and subcellular organelles is critical. We are investigating (1) the molecular mechanisms underlying stem cell quiescence, proliferation, and myogenic commitment, and (2) the novel signaling pathways that control skeletal muscle mass.
Lung
Lung tissue has a vital function in gas exchange between the blood and the external atmosphere. It also has a critical role in the immune defense against external pathogens and environmental factors. While the lung is classified as a relatively quiescent organ with little homeostatic turnover, it shows robust regenerative capacity in response to injury, mediated by the resident stem/progenitor cells. During regeneration, regionally distinct epithelial cell populations with specific functions are generated from several different types of stem/progenitor cells localized within four histologically distinguished regions: trachea, bronchi, bronchioles, and alveoli. WNT signaling is critical to its developmental role in the embryonic and fetal lung. We currently explore how WNT signaling regulates different types of stem/progenitor cells in the lung for regeneration.

Jennifer Fransisca Bachelor of Science, Atma Jaya Catholic University, Indonesia Her research interest is to investigate about skeletal muscle niche components, particularly a group of mesenchymal progenitor cells called Fibro Adipogenic Progenitors (FAPs) that exhibit major impact in supporting muscle regeneration while become the main source of adipocyte and fibroblast infiltration in pathological muscle conditions. Bagus Sarmito Bachelor of Science, Atma Jaya Catholic University, Indonesia He is primarily interested in understanding the molecular mechanism by which skeletal muscle mass is regulated. Currently, he is studying a previously unknown role of chemokine CXCL14 in the regulation of skeletal muscle mass.
