GROWTH OF FOREIGN CELLS IN FETAL ANIMALS FACILITATED BY CONDITIONAL AND SELECTIVE DESTRUCTION OF NATIVE HOST CELLS

摘要

Foreign cells can be grown in fetal non-mammalian hosts for the production o f transplant organs and tissues, the development of new therapeutic agents, an d the production of biological factors and drugs. Tissue-specific injury to fetal host target cells is carried without substantial injury to the materna l host or foreign cells, providing an environment in which the injured tissue can be regenerated with the foreign cells.
