白血病抑制因子（Leukemia inhibitory factor，縮寫 LIF）化學式為：C₁₄₈₄H₂₃₈₁O₆₇₇N₂₉₃S₇^[5]，是一種屬於白介素-6大類的細胞因子。它能通過抑制分化影響細胞生長。LIF水平下降會使細胞開始分化。

功能

白血病抑制因子能夠誘導骨髓性白血病細胞的末端分化，進而阻止其生長，因而得名。白血病抑制因子還有以下功能：能促進多種細胞的生長與分化，影響骨代謝、惡病質體、神經發育（英語：Neural development），胚胎發育以及發炎作用。受p53調控的白血病抑制因子能促進小鼠和人的胚胎著床^[6]。一篇文章提出重組人白血病抑制因子可能可以提高意外懷孕的婦女（體內胚胎）的著床成功率^[7]。

表達

LIF在正常情況下會由囊胚中的滋養層（TE）表達，而其受體LIFR則會由內細胞群（ICM）的細胞表達。胚胎幹細胞取自內細胞群的細胞，在體外培養時就需要額外補充LIF。目前，重組LIF已可以通過基因工程的手段由植物（水稻）產生^[8]。

幹細胞培養

幹細胞培養基中大都含有LIF，可用於替代餵養層（feeder layer）細胞，因爲餵養層細胞的主要作用即產生LIF。不表達LIF基因的餵養層細胞難以支持幹細胞的培養^[9]。LIF通過招募信號誘導分子以及轉錄活化因子3（STAT3）促進細胞的自我更新。活化的LIFR能徵募Stat3。隨後，JAK激酶能將其磷酸化。不過LIF和Stat3是不足以阻止細胞分化的，一旦移去培養基中的血清，幹細胞就會分化。在原生多能性幹細胞分化的可逆階段，加入LIF可以使細胞重回原生多能性階段^[10]^[11]^[12]。
