摘要
By transfecting an Oct-4 expression plasmid Into embryonic stem cells (ES cells), the ES-O cell line was constructed, which sustained the expression of Oct-4 gene when induced by retinoic acid. Forced expression of Oct-4 gene could not sustain the stem property of ES-O cells without the differentiation inhibiting factor LIF, but if LIF exists, forced expression of Oct-4 gene could enhance the ability to sustain the undifferentiation state and Inhibit cell differentiation induced by retinoic acid. It was Indicated that Oct-4 must cooperate with LIF to sustain the undifferentiation state of ES cells. During the cell differentiation, ES-O cells tend to differentiate Into neural cells, suggesting that forced expression of Oct-4 gene may be In relation with the differentiation of neuroderm.
