  • UGT1A1 enzyme defects are responsible of both Gilbert syndrome (GS) and Crigler-Najjar syndrome (CNS). GS depends on a variant TATAA element (which contains two extra TA nucleotides as compared to the wild type genotype) in the UGT1A1 gene promoter resulting in a reduced gene expression. On the cont

  • Increased Reprogramming of Human Fetal Hepatocytes Compared With Adult Hepatocytes in Feeder-Free Conditions.
  • Hansel MC, Gramignoli R, Blake W, Davila J, Skvorak K, Dorko K, Tahan V, Lee BR, Tafaleng E, Guzman-Lepe J, Soto-Gutierrez A, Fox IJ, Strom SC.AbstractHepatocyte transplantation has been used to treat liver disease. The availability of cells for these procedures is quite limited. Human embryonic stem cells (hESCs) and inducedpluripotent stem cells (hiPSCs) may be a useful source of hepatocytes for basic research and transplantation if efficient and effective differentiation protocols were developed and problems with tumorigenicity could be overcome. Recent evidence suggests that the cell of origin may affect hiPSC differentiation. Thus, hiPSCs generated from hepatocytes may differentiate back to hepatocytes more efficiently than hiPSCs from other cell types. We examined the efficiency of reprogramming adult and fetal human hepatocytes. The present studies report the generation of 40 hiPSC lines from primary human hepatocytes under feeder-free conditions. Of these, 37 hiPSC lines were generated from fetal hepatocytes, 2 hiPSC lines from normal hepatocytes and 1 hiPSC line from hepatocytes of a patient with Crigler-Najjar Syndrome, Type-1. All lines were confirmed reprogrammed and expressed markers of pluripotency by gene expression, flow cytometry, immunocytochemistry, and teratoma formation. Fetal hepatocytes were reprogrammed at a frequency over 50-fold higher than adult hepatocytes. Adult hepatocytes were only reprogrammed with 6 factors, while fetal hepatocytes could be reprogrammed with 3 (OCT4, SOX2, NANOG) or 4 factors (OCT4, SOX2, NANOG, LIN28 or OCT4, SOX2, KLF4, C-MYC). The increased reprogramming efficiency of fetal cells was not due to increased transduction efficiency or vector toxicity. These studies confirm that hiPSCs can be generated from adult and fetal hepatocytes including those with genetic diseases. Fetal hepatocytes reprogram much more efficiently than adult, although both could serve as useful sources of hiPSC-derived hepatocytes for basic research or transplantation.

Crigler-Najjar syndrome


  • グルクロニルトランスフェラーゼの機能欠損。
  • 原因遺伝子は2q37.1に座乗するUGT1A1遺伝子である。この遺伝子がコードするUDP-グルクロノシルトランスフェラーゼ(UDP-glucuronosyltransferase ,UDPGT)は間接ビリルビンにグルクロン酸抱合を行い直接ビリルビンに変換する。
  • I型ではUDP-グルクロノシルトランスフェラーゼが完全に機能欠損し、II型は活性が低下したものである。



  • フェノバルビタール投与によりビリルビン濃度の変化により分類される。  ←  フェノバルビタールによりUDP-グルクロノシルトランスフェラーゼの発現が誘導される、らしい。
  • I型:フェノバルビタール投与で変化なし。
  • I型:フェノバルビタール投与でビリルビン低下。


  • 間接ビリルビンが上昇。
  • I型
  • 生後まもなく間接ビリルビン上昇により核黄疸に至る。
  • 予後不良
  • II型
  • UDP-グルクロノシルトランスフェラーゼの活性は正常人の1/10以下であるが、予後良好。


  • I型:光線療法、肝移植
  • II型:光線療法、フェノバルビタール、肝移植?
