Lineage negative (lin-) cell isolation, differentiation and characterization from umbilical cord blood/ Zulinda Ayu Zulkipli

Among the well-established and mostly studied adult stem cells, umbilical cord blood-derived lineage negative (lin") cells were chosen to be studied. The stem cell has been regarded to have many potential applications due to its ability for selfrenewal and differentiation. Studies presented her...
