Pattern diagram showing various types of HDDPCs with respect to the expression of the stemness factors. Among OCT3/4-positive HDDPCS, some cells express SOX2, but other cells do not. ALP-positive cells express both ALP and OCT3/4 or OCT3/4 alone, but ALP-negative cells fail to express both. OCT3/4-positive cells express ALP or SOX2. However, there are no cells expressing the three factors simultaneously. Furthermore, some HDDPCs expressed SOX2 even in the absence of ALP expression
