LGR5 (GPR49) (loop1) Antibody

Background

LGR5 is another member of the LGR family, closely associated with stem cell maintenance and tissue regeneration. It is highly expressed in adult stem cells of various tissues, including the intestines, hair follicles, and the mammary gland. LGR5 is a key player in regulating Wnt signaling, a pathway that controls stem cell proliferation, self-renewal, and differentiation. In the intestines, LGR5+ stem cells are essential for maintaining the intestinal epithelium and enabling tissue regeneration after injury. LGR5 is also involved in the formation and progression of tumors, particularly in colorectal cancer, where LGR5+ cells contribute to tumor initiation and metastasis. Research into LGR5 is actively exploring its role as a biomarker for cancer and its potential as a target for cancer therapies that aim to disrupt the Wnt signaling pathway and inhibit tumor growth. Additionally, LGR5 is being studied for its role in tissue repair and stem cell therapies.
