Precursor cell
In cytology, a precursor cell is a type of partially differentiated, usually unipotent cell that has lost most or all of the stem cell multipotency.
Usually precursor cells are cells capable of differentiating into one or two closely related final forms. Sometimes precursor cell is used as an alternative term for multipotent stem cells.
A blastoma is a type of cancer created by malignancies of precursor cells.
In embryology, precursor cells are group of cells what differentiate later into one organ.
