A Sex Difference in White Blood Cells of Rats (WR Strain)

A search was made for a biological marker characteristic of the donor identifiable in the host and the presence of a structural difference between nuclei of male and female neutrophilic leucocytes as described for humans1, rabbits2, and dogs3 was confirmed also for rats.
