Definition of Cell fusion
Cell fusion: The melding of two or more cells into one cell called a heterokaryon. A heterokaryon may reproduce itself for at least several generations. Cell fusion provides a method for assigning specific genes to specific chromosomes.
When an undifferentiated stem cell fuses with a mature differentiated cell, the resultant cell can retain the mature cell phenotype.Source: MedTerms™ Medical Dictionary
