| 1 | Tonsil-derived stem cells as a new source of adult stem cells显示文摘Located near the oropharynx, the tonsils are the primary mucosal immune organ. Tonsil tissue is a promising alternative source for the high-yield isolation of adult stem cells, and recent studies have reported the identification and isolation of tonsil-derived stem cells (T-SCs) from waste surgical tissue following tonsillectomies in relatively young donors (i.e., under 10 years old). As such, TSCs offer several advantages, including superior proliferation and a shorter doubling time compared to bone marrow-derived mesenchymal stem cells (MSCs). T-SCs also exhibit multi-lineage differentiation, including mesodermal, endodermal (e.g., hepatocytes and parathyroid-like cells), and even ectodermal cells (e.g., Schwann cells). To this end, numbers of researchers have evaluated the practical use of T-SCs as an alternative source of autologous or allogenic MSCs. In this review, we summarize the details of T-SC isolation and identification and provide an overview of their application in cell therapy and regenerative medicine. | Kyung-Ah Cho Hyun Jung Lee Hansaem Jeong Miri Kim Soo Yeon Jung Hae Sang Park Kyung-Ha Ryu Seung Jin Lee Byeongmoon Jeong Hyukjin Lee Han Su Kim | 2019 | World Journal of Stem Cells2019，11，8： | 2 |

| 3 | Silver nanoislands on cellulose fibers for chromatographic separation and ultrasensitive detection of small molecules显示文摘High-throughput small-molecule assays play essential roles in biomedical diagnosis,drug discovery,environmental analysis,and physiological function research.Nanoplasmonics holds a great potential for the label-free detection of small molecules at extremely low concentrations.Here,we report the development of nanoplasmonic paper(NP-paper)for the rapid separation and ultrasensitive detection of mixed small molecules.NP-paper employs nanogap-rich silver nanoislands on cellulose fibers,which were simply fabricated at the wafer level by using low-temperature solid-state dewetting of a thin silver film.The nanoplasmonic detection allows for the scalable quantification and identification of small molecules over broad concentration ranges.Moreover,the combination of chromatographic separation and nanoplasmonic detection allows both the highly sensitive fluorescence detection of mixed small molecules at the attogram level and the label-free detection at the sub-nanogram level based on surface-enhanced Raman scattering.This novel material provides a new diagnostic platform for the high-throughput,low-cost,and label-free screening of mixed small molecules as an alternative to conventional paper chromatography. | Hyukjin Jung Moonseong Park Minhee Kang Ki-Hun Jeong | 2016 | Light(Science & Applications)2016，5，1： | 0 |
| 4 | Customized 3D-printed occluders enabling the reproduction of consistent and stable heart failure in swine models显示文摘Reproducibility of clinical output is important when investigating therapeutic efficacy in pre-clinical animal studies.Due to its physiological relevance,a swine myocardial infarction(MI)model has been widely used to evaluate the effectiveness of stem cells or tissue-engineered constructs for ischemic heart diseases.Several methods are used to induce MI in the swine model.However,it is difficult,using these approaches,to obtain a similar level of functional outcomes from a group of animals due to interpersonal variation,leading to increased experimental cost.Hence,in order to minimize human intervention,we developed an approach to use a customized occluder that has dimensional similarities with that of the coronary artery of animals in the case of the swine model.We carried out angiography to measure the diameter of the middle left anterior descending artery of each individual animal to fabricate the customized occluder using a 3D-printing system.The fabricated occluder contained a central hole smaller than that of the targeted middle left anterior descending artery to mimic an atherosclerotic coronary artery that has an approximately 20%blocked condition.Interestingly,the 3D-printed occluder can provide continuous blood flow through the central pore,indicating a high survival rate(88%)of up to 28 days post-operation.This method showed the possibility of creating consistent myocardial infarction induction as compared to the conventional representative closed-chest method(50%survival rate),thus highlighting how our method can have a profound effect on accelerating reliable experiments for developing new therapeutic approaches to ischemic heart diseases. | Han B.Kim Seungman Jung Hyukjin Park Doo S.Sim Munki Kim Sanskrita Das Youngkeun Ahn Myung H.Jeong Jinah Jang Young J.Hong | 2021 | Bio-Design and Manufacturing2021，4，4： | 0 |
