개요

SToFM은 다중 스케일 공간 전사체 데이터를 분석하기 위한 새로운 기초 모델입니다. 거대하고 복잡한 공간 전사체 데이터에서 다중 스케일 정보 (거시적 조직 형태, 미시적 세포 미세 환경, 유전자 수준의 유전자 발현 프로파일)를 추출하는 과정의 어려움을 해결하기 위해 제안되었습니다. SToFM은 각 ST 슬라이스에 대해 다중 스케일 정보 추출을 수행하여 거시, 미시 및 유전자 스케일 정보를 집계하는 ST 하위 슬라이스 세트를 구성합니다. 그런 다음 SE(2) Transformer를 사용하여 하위 슬라이스에서 고품질 세포 표현을 얻습니다. 또한, 사전 훈련을 위한 가장 큰 고해상도 공간 전사체 코퍼스인 SToCorpus-88M을 구축했습니다. 조직 영역 의미론적 분할 및 세포 유형 주석과 같은 다양한 하위 작업에서 뛰어난 성능을 달성하여 다중 스케일 정보의 포착 및 통합을 통한 ST 데이터에 대한 포괄적인 이해를 보여줍니다.
