Abstract:

BACKGROUND: Recent studies have shown that cancer stem cells play a key role in the development of tumors, therefore, the research about cancer stem cells’ markers can deepen the understanding of the development and clinical diagnosis of the tumor.
OBJECTIVE: To review the research progression of stem cell marker LGR5.
METHODS: The first author retrieved PubMed database and Wanfang database for papers regarding LGR5 and stem cell/cancer stem cell published between January 1998 and December 2014 using the key Words “LGR5, stem cell, cancer stem cell” in English and Chinese, respectively. A total of 178 papers were initially retrieved. After 123 papers with independent objective and out-of-date contents were excluded, 55 papers were suitable for final analysis.
RESULTS AND CONCLUSION: LGR5 is the surface marker of intestinal, stomach, hair follicle stem cells, which has a great relationship with occurrence, development and prognosis of colorectal cancer, stomach cancer, lung cancer, ovarian cancer, liver cancer, basal cell carcinoma. As a candidate marker of cancer stem cells, LGR5 can be the new treatment target. Studies have shown that R-spondins (RSPOs) is a high affinity ligand of LGR5. They participate in the Wnt signaling pathway, regulating cell proliferation and differentiation.
