Abstract
Transgenic nonhuman mammals, such as transgenic mice, which lack erythropoietin expression, in which the erythropoietin receptor is deleted, which carry a heterologous erythropoietin receptor (e.g., a chimeric receptor); constructs useful for producing such transgenic nonhuman mammals, embryonic stem cells containing the constructs, a method of producing the transgenic nonhuman mammals and a method of identifying erythropoietin mimics or mimetics.
