A cloned horse born to its dam twin

Article Abstract:

Somantic cell cloning technology is used to clone an adult horse in order to show that it is possible to establish a viable, full-term pregnancy in which the surrogate mother is also the nuclear donor. The findings indicate that the cloned offspring is identical to the mare that carried it, challenging the idea that maternal immunological recognition of fetal antigens influences the well-being of the fetus and the outcome of the pregnancy.
