Figure 2From: Insulin Decreases Inflammatory Signal Transcription Factor Expression in Primary Human Liver Cells after LPS ChallengePCR characterization of primary human hepatocytes. (A) PHHs obtained by standard isolation protocol showed a low percentage of nonparenchymal cells. (B) Additional purification of PHHs by density gradient centrifugation resulted in highly purified PHHs with no detectable Kupffer cells (CD68).Back to article page
