Abstract
The potential of cells derived from human umbilical cord(UC) for orthopaedic cell engineering is evaluated by dissecting the UC into four distinct anatomical structures – cord lining (CL), Wharton's Jelly (WJ), umbilical cord artery (UCA) and umbilical cord vein (UCV). Cells from individual anatomical layers were grown by explant culture technique for 21 days. Tri-lineage differentiation and growth kinetics of cells from each layer were compared. Flowcytometry was done according to ISCT criteria to ascertain their surface antigen expressions. Cells from all four layers differentiated into bone, cartilage and fat. Osteogenic and chondrogenic differentiation was variable for each type of cells. All cells expressed surface antigens characteristic of mesenchymal stem cells (MSC). These cells can form a potential cell source in cell engineering to produce bone and cartilage although individual cell type needs to be characterised from each anatomical layer of UC and identify the best cell type for cell engineering.
