A primate as messiah

APES might come to the rescue Oour AfDS-infected planet. After a pro- longed period of deliberations, the us Food and Drug Administration (FDA) has given the green signal to a revolutionary experiment that might lead to the discovery of a cure for this deadly disease.

The process involves injecting baboon bone marrow cells into an AIDS patient to see if they can help rebuild his ravaged immune system. The theory is that baboon stem cells (which are part of the bone marrow cells) might help repopulate a human being's blood with immune cells.

Of course, the experiment involves serious risks. A FDA advisory committee has warned that the recipient candidate might die if diseases that baboons carry spread within his body.
