The Dynamic Roles of Mesenchymal Stem Cells in Colon Cancer

Abstract

Colon cancer is still one of the most common causes of cancer in human and is characterized by lymphocyte infiltrates and originates from the epithelial cells found in the lining of colon or rectum of the gastrointestinal tract. Mesenchymal stem cells (MSCs) are composed of the multipotent stem cell group of stroma and can be differentiated as various cell lineages, such as fibroblasts, osteoblasts, and adipocytes. MSCs provide mechanical and structural support and have potential functions during tumor growth and metastasis. The efficacy of MSC-based therapies is partly dependent on the migration and homing of MSCs to tumors and metastatic sites. However, their migratory and engraftment potential is poorly understood. In this review, the characteristics and mechanisms of MSC's dynamic interaction with colon cancer were summarized, particularly the potential functions of MSCs on colon cancer, including its role in improving tumor growth and as a potential candidate for tumor therapy. Understanding MSC homing provides new insights into the manipulation of MSC and the improvement of their efficacy for colon cancer therapy.

Checking NEKs: Overcoming a Bottleneck in Human Diseases

“…Colorectal cancer (CRC) is one of the most common cancers diagnosed in humans and is an important cause of mortality worldwide. The accumulation of mutations in epithelial and preneoplastic cells, which is thought to be linked to a combination of lifestyle habits and genetic factors such as smoking, aging, diet, and obesity, is probably a major cause of the development of this cancer [82].…”

Premetastatic niches, exosomes and circulating tumor cells: Early mechanisms of tumor dissemination and the relation to surgery

“…BMDC, and importantly the subgroup of myeloid‐derived suppressor cells (MDSC) need to colonize the PMN before the arrival of CTC . To mobilize BMDC, TSF stimulates the bone marrow compartment, switching it from a quiescent state to a highly pro‐angiogenic and pro‐tumorigenic state.…”

The Achievements and Challenges of Mesenchymal Stem Cell-Based Therapy in Inflammatory Bowel Disease and Its Associated Colorectal Cancer

“…MSCs, as none hematopoietic precursor cells, possess several properties including their capability to differentiate to produce different kinds of cells like adipocytes, osteocytes, fibroblasts, and neurocytes [8]. They are resident within bone marrows and found in certain other tissues like umbilical cord blood, adipose, and dental pulp and assist homeostasis in healthy tissues in the process of wound healing and regeneration.…”
