¢º 3D scaffolds' for tissue regeneration


In natural tissues, the three-dimensional (3D) extracellular matrix (ECM) comprises various types of cells, including fibroblasts, stem cells, and endothelial cells, which communicate with each other directly or indirectly to regulate matrix production and cell functionality. To engineer multicellular interactions in vitro, co-culture systems have achieved tremendous success in achieving more realistic microenvironment of in vivo metabolism than monoculture system. For this reason, we fabricate biomimetic cellular scaffolds and develop co-culture system using various types of cells.

We are exploring stem cell therapy for injured tissue regeneration with developed biomimetic scaffold which can control stem cell fate. 3D encapsulation strategy produces microenvironment from which stem cell differentiate into new tissue. This approach is being utilized to promote tissue regeneration, angiogenesis, Drug screening, Artificial tissue. and other applications.

¢ºChronic kidney disease treatment


Polycystic kidney disease(PKD) is a genetic disorder that causes proliferation and enlargement of the renal cyst. Although much has been done in the determining molecular mechanism of the disease, progress on detection and treatment of the PKD have been slow. Our group focuses on research to realize early detection, treatment, and management of PKD. We use the various scientific method from chemical synthesis to molecular biology techniques for our research.

¢º Hydrogel fillers for breast reconstruction


Breast reconstruction surgery has been recently increased since breast cancer patients have frequently used mastectomy more frequently. However, standard PDMS breast implants have problems such as unfavorable immune reaction and additional surgery. Conventionally practiced, incision-based breast reconstruction method is going toward non-surgical breast reconstruction. In this manner, the filler for the local site injection has been partially used as a substitute for the implant.

¢º 3D bioprinting


3D bioprinting technology is a combination of 3D printing technology and biotechnology. With this cutting-edge technology, living cells can be rendered into desired shapes or patterns to engender tissues or organs; nonetheless, appropriate bio-ink is required to realize it. There are four significant characteristics in developing bio-ink which are printability, bio-compatibility, tunable gelation, and biomimetics. With appropriate bio-ink developed, 3D bioprinting is then made suitable for various biomedical applications, such as drug delivery, organoid, and diagnosis.

3D printing is regarded as a versatile technique for tissue engineering due to the ability to print complex 3D structures similar to that of the human tissue. It is a method requiring a precise control that deposits various materials such as polymers, ceramics, and hydrogels. 3D printing has become prominent technique in medical fields for its possible applicability in specific shaping on patient's demand
