The prostate glands of wild ground squirrels display enlarged volume during the breeding season and shrunk size during the nonbreeding season, which enables the wild ground squirrel to be an ideal animal model for studying the mechanisms of prostate growth and involution. To clarify the possible mechanism underlying seasonal morphological changes of the prostate in wild ground squirrels, epithelial-mesenchymal transitions (EMT) were focused, and the expression of EMT-related genes was investigated in the current study. Histological results showed that the epithelial lumen enlarged in the breeding season, and the stromal cells expanded during the non-breeding season.

Acoustic bioassembly is recently regarded as a highly efficient biofabrication tool to generate functional tissue mimics. Despite their capacity of directly patterning live cells with close intercellular proximity, most acoustic bioassembly techniques are currently limited to generate some specific simple types of periodic and symmetric patterns, which represents an urgent challenge to emulate geometrically complex cytoarchitecture in human tissue. To address this challenge, we herein demonstrate a soft-lithographically defined acoustic bioassembly (SLAB) technique that enables to assemble live cells into geometrically defined arbitrary multicellular structures.
