Which type of cell exhibits a high rate of mitosis and closely resembles undifferentiated mesenchymal cells from its original tissue?

Explanation

Anaplastic cells are characterized by an increased rate of cell division and a lack of differentiation, making them similar to primitive mesenchymal cells of the same lineage. Dysplastic cells show abnormal growth but not to the extent of anaplasia. Metaplastic cells undergo a change from one differentiated type to another. Hyperplastic cells have an increased number but maintain normal differentiation.
