Fig. 4: Cross-sectional images of mouse blastocyst-stage embryos.

a Airy LSM image (LR) is deconvolved with Richardson–Lucy (RL) and deep-learning (DL) deconvolution, and compared with a Gaussian LSM (G). b Intensity profiles marked by the red arrows in (a). c Cross-sections of blastocyst-stage embryos imaged with a Gaussian LSM (G) and compared to an Airy LSM with deep-learning deconvolution (DL). Profiles marked by the red triangles are displayed as insets. Scale bar is 50 μm
