This study defines the spatial architecture of human subgingival biofilms using fluorescence in situ hybridization and microscopy, revealing structured microbial consortia associated with periodontitis.

This study shows that transient cartilage-specific cell death in fetal mouse limbs is repaired through a two-step process involving delayed and then accelerated chondroprogenitor differentiation, with mTORC1 activation playing a key role in recovery.
