Background: The heterogeneity within breast cancer and its microenvironment are associated with metastasis. Analyzing distinct tumor subregions using habitat analysis and characterizing the tumor microenvironment through radiomics may be valuable for predicting axillary lymph node metastasis (ALNM) in breast cancer. This study aimed to develop and validate a nomogram for predicting ALNM in breast cancer patients by integrating clinicopathological, intra- or peri-tumoral radiomic, and habitat signatures based on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and determine the optimal peritumoral region size for accurate prediction.

Medicinal plant stem cells are separated from the meristem and vascular cambium of medicinal plants, which can produce active components for preventing and treating diseases and improving body physical functions under certain conditions. Medicinal plant stem cells come from a broad category of medicinal plants, including ethnic medicinal plants, folk medicinal plants, original plants of health products, vegetables, fruits, and other potential medicinal plants. At present, the techniques for the isolation, identification, preservation and culture of medicinal plant stem cells have become increasingly mature, and the mechanism of stem cell differentiation, growth and regulation of secondary metabolites has been studied in depth.
