LncRNA HULC promotes epithelial and smooth-muscle-like differentiation of adipose-derived stem cells by upregulation of BMP9.

Aims: Adipose-derived stem cells (ADSCs), a source of mesenchymal stem cells, are able to differentiate into numerous cell lineages, including epithelial and smooth muscle cells. The use of ADSCs in tissue engineering technology has become the most promising therapeutic approach for urethral reconstruction. This study aimed to explore the effect of lncRNA highly upregulated in liver cancer (HULC) on the induction of ADSCs to differentiate into epithelial and smooth-muscle-like cells.

Cathelicidin LL37 Promotes Epithelial and Smooth-Muscle-Like Differentiation of Adipose-Derived Stem Cells through the Wnt/β-Catenin and NF-κB Pathways.

Ureter reconstruction is a difficult procedure in urology. Adipose-derived stem cells (ADSCs), along with multipotency and self-renewal capacity, are a preferred choice for tissue engineering-based ureteral reconstruction. We explored the synergic role of cathelicidin LL37 (LL37) in epithelial and smooth-muscle-like differentiation.
