ERRATUM

In the article by Ichibara et al, entitled “Oncostatin M and Leukemia Inhibitory Factor Do Not Use the Same Functional Receptor in Mice,” which appeared in the July 1, 1997 issue (Vol 90, No 1, pp 165-173), a correction should be noted. The legend to Figure 2 is incorrect. The open and closed circles are reversed; ie, mOSM should be open circles and mLIF should be closed circles. The correct figure legend is as follows:

Fig. 2. Comparison of biological activities between mOSM and mLIF. (A) Inhibition of [³H]thymidine uptake in mouse M1 myeloid leukemia cells by mOSM (○) and mLIF (•). (B through D) Growth stimulation of mouse myeloid DA1a cells (B), a Ba/F3 transfectant expressing gp130 and LIFRβ (C), and a Ba/F3 expressing gp130 alone (D). As a control in (D), various concentrations of human IL-6 were added in the presence of 100 ng/mL of soluble human IL-6 receptor α subunit (open triangles with broken line). Data are averages of duplicate measurements.
