| Description |
The CD146 MicroBead Kit was developed for the isolation of CD146+ cells. The kit consists of CD146 MicroBeads and FcR Blocking Reagent. The CD146 MicroBeads recognize the human CD146 antigen, also known as MUC18, MCAM, Mel-CAM, and S-Endo-1. CD146 is a transmembrane glycoprotein belonging to the immunoglobulin superfamily and contains five extracellular immunoglobulin (Ig)-like domains.1,2
CD146 possesses a limited tissue expression distribution, including endothelial cells, smooth muscle cells, pericytes, follicular dendritic cells, melanoma cells, and a subpopulation of activated T lymphocytes.1,3 CD146+ cells isolated from umbilical cord4, lipoaspirate5, dental pulp, or endometrial tissue6, are described to contain cells with clonogenic fibroblastic colony (CFU-F) activity and multilineage differentiation potential, which are often called mesenchymal or marrow stromal cells (MSCs).
CD146 functions as a Ca2+-independent cell adhesion molecule, which is involved in heterophilic cell-cell interactions7, and may be involved in the extravasion and/or homing of activated T cells3. CD146 expression in melanoma is also directly associated with tumor growth and metastasis.7,8

| Applications |
The CD146 MicroBead Kit can be used for:
- isolation of human mesenchymal stromal cells (MSCs) from lipoaspirate and other tissue sources,
- isolation of endothelial cells and pericytes from human tissue,
- isolation of human umbilical vein endothelial cells (HUVECs) and human umbilical cord perivascular cells (HUCPVCs)4 from umbilical cord vein.
