- Abstract
- Leukemia-inhibitory factor (LIF) elicits effects on a broad range of cell types, including cells of the monocytic and megakaryocytic series, embryonal stem cells, hepatocytes, adipocytes, and osteoblasts. Native and recombinant LIF, injected intravenously into adult mice, had an initial half-life of 6-8 min and a more prolonged second clearance phase. Clearance of I-125-LIF from the circulation was paralleled by a rapid accumulation in the kidneys, liver, lungs, and spleen and a more gradual accumulation in the thyroid gland. Labeling of the renal glomerular tufts, parenchymal hepatocytes, splenic red pulp, alveolar pneumocytes, and thyroid follicular cells as well as of megakaryocytes and osteoblasts in the bone cavities, placental trophoblasts, and cells of the choroid plexus was demonstrable autoradiographically. The appearance of a large amount of nonprecipitable I-125 in the urine suggested that the kidneys were the major route of LIF clearance from the body.
