liver/biliary system
decreased hepatocyte proliferation ( J:144766 )
• following partial hepatectomy, proliferation of pIpC-treated hepatocyte is decreased compared to in wild-type mice due to accumulation of DNA damage
• however, a subset of hepatocytes resolve their DNA damage and divide
abnormal hepatocyte morphology ( J:144766 )
• while liver regeneration following partial hepatectomy is normal, pIpC-treated hepatocytes exhibit an increase in DNA damage compared to wild-type cells
• however, a subset of hepatocytes resolve their DNA damage and divide
liver hypoplasia ( J:144766 )
• following partial hepatectomy, pIpC-treated livers exhibit reduced cellularity and endoreduplication compared to in similarly-treated wild-type mice

hematopoietic system
decreased bone marrow cell number ( J:144766 )
• the only viable bone marrow left after treatment with pIpC fails to exhibit recombination
