Professor Youngmee Jung's research lab specializes in tissue engineering and regenerative medicine, focusing on the development of advanced biomaterials and scaffolds for cartilage, bone, vascular, and organ regeneration. The lab pioneers innovative strategies such as 3D bioprinting, scaffold-free tissue constructs, and stimuli-responsive drug delivery systems to enhance tissue repair and functional integration. Key research directions include designing bioactive nanofibers, elastic biodegradable polymers, and implantable hyperthermia platforms for on-demand cancer therapy. The lab emphasizes mechanobiological cues and dynamic culture systems to improve the mechanical and biological performance of engineered tissues.

Three-dimensional (3D) printing technology allows fabricating complex and precise structures by stacking materials layer by layer. The fabrication method has a strong potential in the regenerative medicine field to produce customizable and defect-fillable scaffolds for tissue regeneration. Plus, biocompatible materials, bioactive molecules, and cells can be printed together or separately to enhance scaffolds, which can save patients who suffer from shortage of transplantable organs. There are va
Tissue-engineered blood vessels (TEBV) can serve as vascular grafts and may also play an important role in the development of organs-on-a-chip. Most TEBV construction involves scaffolding with biomaterials such as collagen gel or electrospun fibrous mesh. Hypothesizing that a scaffold-free TEBV may be advantageous, we constructed a tubular structure (1 mm i.d.) from aligned human mesenchymal cell sheets (hMSC) as the wall and human endothelial progenitor cell (hEPC) coating as the lumen. The bur
The number of patients requiring flat bone transplantation continues to increase worldwide. Cell transplantation has been successfully applied clinically; however, it causes another defect site and the time requirements to harvest cells and expand them are considerable. In this study, KLD12/KLD12-SP (KLD12+KLD12-substance P [SP]) was designed to mimic endogenous tissue-healing processes. The structures of KLD12, KLD12-SP, and KLD12/KLD12-SP were observed by transmission electron microscopy and c
In cartilage tissue regeneration, it is important that an implant inserted into a defect site can maintain its mechanical integrity and endure stress loads from the body, in addition to being biocompatible and able to induce tissue growth. These factors are crucial in the design of scaffolds for cartilage tissue engineering. We developed an elastic biodegradable scaffold from poly(L-lactideco-epsilon-caprolactone) (PLCL) for application in cartilage treatment. Biodegradable PLCL co-polymer was s
Stimuli-responsive delivery systems for cancer therapy have been increasingly used to promote the on-demand therapeutic efficacy of anticancer drugs and, in some cases, simultaneously generate heat in response to a stimulus, resulting in hyperthermia. However, their application is still limited due to the systemic drawbacks of intravenous delivery, such as rapid clearance from the bloodstream and the repeat injections required for sustained safe dosage, which can cause overdosing. Here, we propo
It is known that complex loading is involved in the development and maintenance of articular cartilage in the body. It means the compressive mechanical stimulation is a very important factor for formation of articular cartilage using a tissue-engineering technique. The objective of this study is to engineer cartilaginous constructs with mechano-active scaffolds and to evaluate the effect of dynamic compression for regeneration of cartilage. The mechano-active scaffolds were prepared from a very
