The penultimate effectors of the Hippo signaling pathways YAP and TAZ, are transcriptional co-activator proteins that play key roles in many diverse biological processes, ranging from cell proliferation, tumorigenesis, mechanosensing and cell lineage fate determination, to wound healing and regeneration. In this review, we discuss the regulatory mechanisms by which YAP/TAZ control stem/progenitor cell differentiation into the various major lineages that are of interest to tissue engineering and regenerative medicine applications. Of particular interest is the key role of YAP/TAZ in maintaining the delicate balance between quiescence, self-renewal, proliferation and differentiation of endogenous adult stem cells within various tissues/organs during early development, normal homeostasis and regeneration/healing. Finally, we will consider how increasing knowledge of YAP/TAZ signaling might influence the trajectory of future progress in regenerative medicine.

Increased blood amino acid levels (hyperaminoacidemia) stimulate pancreas expansion by unclear mechanisms. Here, by genetic and pharmacological disruption of glucagon receptor (GCGR) in mice and zebrafish, we found that the ensuing hyperaminoacidemia promotes pancreatic acinar cell proliferation and cell hypertrophy, which can be mitigated by a low protein diet in mice. In addition to mammalian target of rapamycin complex 1 (mTORC1) signaling, acinar cell proliferation required , the most highly expressed amino acid transporter gene in both species.

Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) are key downstream effectors of the Hippo pathway that regulate organ size, tissue homeostasis, and cancer development. YAP/TAZ play crucial regulatory roles in organ growth, cell proliferation, cell renewal, and regeneration. Mechanistically, YAP/TAZ influence the occurrence and progression of liver regeneration (LR) through various signaling pathways, including Notch, Wnt/β-catenin, TGF-β/Smad.

Article Synopsis
  • Progressive fibrosis is caused by the buildup of a collagen-rich extracellular matrix, leading to tissue malfunction and organ failure.
  • The study investigates the role of the PIEZO1 ion channel and mechanosensitive transcription factors YAP/TAZ in adipose-derived stem cells (hASCs), focusing on how substrate architecture affects collagen formation.
  • Findings reveal that PIEZO1 influences collagen synthesis by altering cell morphology and reducing collagen accumulation, highlighting mechanisms that could inform therapeutic strategies for fibrosis and tissue repair.

Myofibers cultured in viscoelastic hydrogels reveal the effects of integrin-binding and mechanosensing on muscle satellite cells.

Quiescent skeletal muscle satellite cells (SCs) located on myofibers activate in response to muscle injury to regenerate muscle; however, identifying the role of specific matrix signals on SC behavior in vivo is difficult. Therefore, we developed a viscoelastic hydrogel with tunable properties to encapsulate myofibers while maintaining stem cell niche polarity and SC-myofiber interactions to investigate how matrix signals, including viscoelasticity and the integrin-binding ligand arginyl-glycyl-aspartic acid (RGD), influence SC behavior during muscle regeneration. Viscoelastic hydrogels support myofiber culture while preserving SC stemness for up to 72 hours post-encapsulation, minimizing myofiber hypercontraction and SC hyperproliferation compared to Matrigel.
