🇰🇷 한글 요약 🌐 Abstract
【연구 목적】
모낭(hair follicle) 줄기세포가 어떻게 미분화 상태로 특정되고 유지되는지를 규명하기 위해, 배아기 모낭 전구세포(progenitor)의 분리 및 전사체 프로파일링 전략을 통해 핵심 전사인자를 탐색하고자 함.
【방법】
마우스 배아의 모낭 전구세포를 분리하여 전사체 분석을 시행하고, 핵심 후보로 도출된 전사인자 Lhx2에 대해 기능획득(gain-of-function) 및 기능상실(loss-of-function) 실험을 수행하여 모낭 줄기세포 유지에 미치는 역할을 검증함.
【주요 결과】
Lhx2는 모낭 줄기세포를 특정하는 신호의 하위(downstream), 그리고 활성화된 줄기세포의 최종 분화를 유도하는 신호의 상위(upstream)에 위치하며, 모낭 전구세포의 성장 유지와 미분화 상태 보존에 필수적인 역할을 함.
【임상적 시사점 (성형외과 의사 관점)】
탈모 치료 및 모발이식(hair transplantation) 분야에서 Lhx2를 표적으로 한 모낭 줄기세포 활성 조절은 모낭 재생 및 미분화 줄기세포 풀(pool) 유지를 통한 치료 전략 개발의 분자생물학적 근거를 제공함. 또한 화상·외상 후 두피 재건이나 흉터성 탈모(cicatricial alopecia) 치료에서 모낭 재생 유도 기술의 잠재적 표적으로 활용 가능성이 있음.
During embryogenesis, stem cells are set aside to fuel the postnatal hair cycle and repair the epidermis after injury. To define how hair follicle stem cells are specified and maintained in an undifferentiated state, we developed a strategy to isolate and transcriptionally profile embryonic hair progenitors in mice. We identified Lhx2 as a transcription factor positioned downstream of signals necessary to specify hair follicle stem cells, but upstream from signals required to drive activated stem cells to terminally differentiate. Using gain- and loss-of-function studies, we uncovered a role for Lhx2 in maintaining the growth and undifferentiated properties of hair follicle progenitors.
