Purified E17 APCs and P1 astrocytes were cultured for 1 hr and immunostained by antibodies against each of the above markers. + indicates >90% of the cells were positive, and − indicates <10% of the cells were positive. Values in between these were considered ±. Approximately 40% of the APCs and astrocytes were nestin⁺.
