Unveils fibroblast diversity in the Achilles tendon, highlighting implications for tissue health and disease.

The study aims to investigate the cellular biology and fibroblast diversity within the human Achilles tendon microanatomy.
Generated a spatially-resolved transcriptomic atlas of the adult Achilles tendon.
Sampled distinct regions including the tendon-bone junction, midbody, myotendinous junction, and adjoining muscle.
Identified and characterized six fibroblast subtypes based on transcriptional profiles and spatial distributions.
Identified six distinct fibroblast subtypes with specialized functions.
Two primary fibroblast types were concentrated in specific regions of the tendon.
Generated data provides insight into cellular diversity, suggesting roles across microanatomically-defined zones.

Cohen et al. (2026) studied this question.
