A MPM image of breast cancer microenvironment showing the spatial distributions of TN, tumor cells, myoepithelium and collagen fibers. B Magnified images showing myoepithelium in the microenvironment, which was a bright red layer in the TPEF images. C Magnified images showing the TN in the microenvironment, which was much brighter than tumor cells in TPEF images. D Magnified images showing tumor cells in the microenvironment. E Magnified images showing the collagen fibers in the microenvironment. Blue arrow: myoepithelium; white arrow: TN; yellow arrow: tumor cells; red arrow: collagen fibers. Scale bar: 100 μm
