Introduction

Somatic cell nuclear transfer (SCNT), also known as “cloning”, rapidly reprograms the somatic transcriptome; it is an efficient, and the first working means to reprogram a differentiated cell to the totipotent state. The best-known example of cloning is Dolly the sheep. This concept later led to the development of two significant types of stem cells. The first one is the induced pluripotent stem cells (iPSCs), initially developed by the 2012 Nobel Prize winner Shinya Yamanaka. The other one is the ntESCs, embryonic stem cells derived from a cloned blastocyst. When combined with gene and cell therapy technologies, ntESCs offer opportunities to treat genetic disorders, hence called by many as “therapeutic cloning.” Both ntESCs and iPSCs can be patient-specific; therefore, they represent a great promise in regenerative medicine and serve as valuable model systems to study many human diseases with a precision medicine approach. 

Professor Sung is an expert in SCNT and among the first to report cloned mice using terminally differentiated postmitotic granulocytes, followed by the efficient derivation of mouse ntESCs. Her team also cloned cattle and rabbits before. She excels in embryonic technologies, such as SCNT, pronuclear microinjection, intracytoplasmic sperm injection, blastocyst injection, cryopreservation of oocyte and embryo, and PSC technology. Her research interests are embryology, developmental biology, stem cell biology, and developing novel animal models to study human diseases, including infertility and xenotransplantation. She is also applying these modern tools to save endangered animals.

The primary research interest of Professor Sung's lab is to understand the process of nuclear reprogramming by somatic cell nuclear transfer (SCNT, also called animal cloning). We also study the biology of oogenesis, embryogenesis, and the stemness of embryonic stem cells.


Research Topics
