Monoclonal antibodies to canine differentiation antigens.

A limited panel of mAbs directed at canine cell populations is available. The number of antibodies is growing, permitting us to learn more about functional properties of the respective cell populations both in vitro and in vivo. Studies such as those dealing with facilitation of engraftment or positive selection of stem cells will be of great importance in clinical marrow transplantation. Consequently, further studies in this canine model are desirable.
