Human peptide hormones, such as insulin, growth hormone, prolactin, adrenocorticotropic hormone, placental lactogen, calcitonin, parathyroid hormone and thyroid stimulating hormone, are produced by implanting a humanxhuman hybridoma lymphoblastoid cell line capable of producing the human peptide hormone in a non-human warm-blooded animal. After a period of time, the resultant tumor is extracted and disaggregated and then cultured in vitro under conditions appropriate to accumulate the human peptide hormone. The humanxhuman hybridoma lymphoblastoid cell line is preferably formed by fusing parent human cells inherently capable of producing the human peptide hormone with a human lymphoblastoid line, preferably of leukemic origin. This process permits a substantial increase in the amount of human peptide hormone which can be produced.
