Traditional concept has been that hematopoietic stem cells (HSC) are tissue-specific stem cells, which are restricted to generate the cell types of the blood and immune system. However, recent studies have shown that there is a higher plasticity of the HSC than previous expected, it can be induced to transdifferentiated into mature cells of other nonhematopoietic organs after transplantation in vivo. In this article, the recent advances in the plasticity of HSC and its potential clinical application are reviewed.

Objective Our retrospective study was aimed to analyze the clinical value of serum CEA and CA19-9 in patients with chole-lithiasis.Methods The clinical data of 98 patients with cholelithiasis and 44 patients with inguinal hernia received treatment in our hospital from February 2011 to February 2015 were retrospectively analyzed.The expressive levels of CEA and CA19-9 of the patients were detected and compared.The important roles of CEA and CA19-9 in the patients with cholelithiasis were analyzed.Results The levels of CEA,CA19-9 and inflammatory factors in normal group and control group had no statistical differences (P>0.05).The levels of CEA,CA19-9 and inflam-matory factors in rising group were higher than those in control group (P<0.05).The levels of CEA,CA19-9,inflammatory factors before and after the treatment had no statistical differences (P>0.05),but the levels of CEA,CA19-9,inflammatory factors in rising group were obvi-ously decreased( P<0.05) .Conclusion The levels of CEA and CA19-9 in patients with cholelithiasis had correlation with inflammation of biliary tract,which will increased by severe choleithiasis.
