The delicate balance between the homeostatic maintenance and regenerative capacity of the intestine makes this a fascinating tissue of study. The intestinal epithelium undergoes continuous homeostatic renewal but is also exposed to a diverse array of stresses that can range from physiological processes such as digestion to exposure to infectious agents, drugs, radiation therapy, and inflammatory stimuli. The intestinal epithelium has thus evolved to efficiently maintain and reinstate proper barrier function that is essential for intestinal integrity and function. Factors governing homeostatic epithelial turnover are well described; however, the dynamic regenerative mechanisms that occur following injury are the subject of intense ongoing investigations. The TGF‐β superfamily is a key regulator of both homeostatic renewal and regenerative processes of the intestine. Here, we review the roles of TGF‐β and BMP on the adult intestinal epithelium during self‐renewal and injury to provide a framework for understanding how this major family of morphogens can tip the scale between intestinal health and disease. Key Findings: The TGF‐β superfamily plays critical roles in both the homeostatic and regenerating intestineTGF‐β itself is of particular importance in the regenerating intestine.BMPs on the other hand regulate homeostasis and repair.Pathway perturbation drives pathogenesis in IBD and cancer [ABSTRACT FROM AUTHOR] |
